Java - public class constructor I need explain on class. What is constructor and how write it and what is public namecllase(){ Here all the variable  } How this is call?   Thank you
Java Constructors I am trying to learn how to specify class constructors in Java. I am starting to understand that they specify the types of instance variables of objects made from that class. They also can be used to set the instance variable initial values. The follow example is from the Java tutorial on Sun's website:  public Bicycle(int startCadence, int startSpeed, int startGear) {     gear = startGear;     cadence = startCadence;     speed = startSpeed; }   Where in your classes source code should you put the constructor(s)?  Are these arguments the names of the variables?: (int startCadence, int startSpeed, int startGear) or are gear, cadence and speed the names of the variables?  What is the difference between (int startCadence, int startSpeed, int startGear) and gear, cadence and speed?  In the unlikely event that my instructor or any administrator from Salt Lake Community College ever comes across this question, let me make my intentions clear. This question is posted in the greatest spirit of academic honesty. I ask this question to seek general advice and help in understanding the proper way to use the Java programming language. I in no way use the work of others and represent it as my own work. I use the answers provided here as a general aid in my understanding. I do all my own work and do not copy work provided by people answering my question.
What is the biggest display of power through the Force in Star Wars? When and where does Attack on Titan take place? Is the setting of "Attack on Titan" (Shingeki no kyojin) supposed to be Earth in the distant future and Titans suddenly appeared out of nowhere and devolved society to medieval level of technology? Or is this just a completely fictional setting? How do you pull first 100 characters of a string in PHP I am looking for a way to pull the first 100 characters from a string variable to put in another variable for printing.    Is there a function that can do this easily?  For example:  $string1 = "I am looking for a way to pull the first 100 characters from a string variable to put in another variable for printing."; $string2 = 100charfunction($string1); print $string2   To get:  I am looking for a way to pull the first 100 characters from a string vari What is the probability that a person is the second person to roll a 6 for the first time? Suppose $A$, $B$, and $C$ roll a die in turns. What is the probability that $A$ is the second person to roll a $6$ for the first time? Is it possible to experimentally show that observable universe is much larger than ~93B ly? NOTE: this question is sorta like a follow-on question to  I asked. In that question, the main suggestion was that I was trying to show two polys. Now, I'm asking about a SINGLE poly.  I have the following GEOGRPAHY of Los Angeles in my Sql Server 2008 :-     (or in )  It's bascially ..  -- Shape of Los Angeles.  DECLARE @WKT VARCHAR(MAX) = 'POLYGON ((-118.66815700000011 34.181235000000029, ... )) SELECT GEOGRAPHY::STGeomFromText(@WKT, 4326)   Now when I just try and render this out, It now looks like this (NOTE: this is different, but still not correct .. compared to my previous GIS Question).    Now, in the previous question people were suggesting that the previous data was a MULTIPOLYGON so there was some bad stuff I must have been doing, trying to render out holes in polys.  This time, this is a single polygon. So i'm assuming the hole theory still doesn't work. Now, I understand that by looking at this image, there's a number of holes ... but the Well Known Text data which Sql Server gives me is a POLYGON which to me means .. one single shape. So i'm not sure how I can fix this :(  This is why i'm asking the a similar question to my previous one.  Can anyone help? Can they see the data I've posted and see what happens in other systems? (I don't have any other software besides Sql Server 2008).  Maybe I need to extract all my data from Sql Server 2008 .. and clean it up (whatever that means) through another system. For example. If Sql Server is saying that the shape of Los Angeles is a single Polygon .. but when cleaned up .. it's actually 7 Polygons .. and then those shapes then get rendered correctly .. then we have a solution!   Any suggestions?  Can -anyone- render this shape onto a Google map? How many characters have appeared in both Marvel and DC comics? The  (the character from Guardians of the Galaxy) says that she has appeared in both Marvel comics as Mantis and DC comics as Willow because her creator "took her with him".     After leaving Marvel Comics, writer Steve Englehart carried Mantis' tale through two other companies before returning to Marvel. In DC Comics' Justice League of America #142, she appears as Willow. Asked where she came from, Willow replies, "This one has come from a place she must not name, to reach a place no man must know." (Mantis refers to herself as "this one").   Are there any other examples of a character appearing in both Marvel and DC comics?  Especially if it's because the original creator has switched companies but still wants to utilize the same character, even under a different name?

Helvetica font has jagged edges I use 'Helvetica' as my font and build my document using Texmaker. But the PDF generated has jagged edges while using this font and when I use a different font (say Times or even Helvetica sans-serif) it builds just fine.     Please suggest if there is anyway I can get over this. The problem with these jagged edges is that it appears very dull and unreadable at 100% resolution.

Whereas in the past, divorce was a relatively rare occurrence, in recent times it has become quite commonplace. This change is borne out clearly in census figures. For example thirty years ago in Australia, only one marriage in ten ended in divorce; nowadays the figure is more than one in three (Australian Bureau of Statistics, 1996: p.45). A consequence of this change has been a substantial increase in the number of single parent families and the attendant problems that this brings (Kilmartin, 1997).   \end{document} Control Cycles/Eevee material nodes and material properties using python? $X$ is homeomorphic to $X\times X$ (TIFR GS $2014$) Question is :  Suppose $X$ is a topological space of infinite cardinality which is homeomorphic to $X\times X$. Then which of the following is true:   $X$ is not connected. $X$ is not compact $X$ is not homeomorphic to a subset of $\mathbb{R}$ None of the above.   I guess first two options are false.  We do have possibility that product of two connected spaces is connected.  So, $X\times X$ is connected if $X$ is connected. So I guess there is no problem.  We do have possibility that product of two compact spaces is compact.  So, $X\times X$ is compact if $X$ is compact. So I guess there is no problem.  I understand that this is not the proof to exclude first two options but I guess the chance is more for them to be false.  So, only thing I have problem with is third option.  I could do nothing for that third option..  I would be thankful if some one can help me out to clear this.  Thank you :) How can I include a YAML file inside another? So I have two YAML files, "A" and "B" and I want the contents of A to be inserted inside B, either spliced into the existing data structure, like an array, or as a child of an element, like the value for a certain hash key.  Is this possible at all? How? If not, any pointers to a normative reference? How do I install applications in Ubuntu? How can I install applications like Google Chrome on Ubuntu?  Are there any commands to install an application?    Index of answers: Why not use the Lagrangian, instead of the Hamiltonian, in nonrelativistic QM? Undergraduate classical mechanics introduces both Lagrangians and Hamiltonians, while undergrad quantum mechanics seems to only use the Hamiltonian. But particle physics, and more generally quantum field theory seem to only use the Lagrangian, e.g. you hear about the Klein-Gordon Lagrangian, Dirac Lagrangian, Standard Model Lagrangian and so on. Why is there a mismatch here? Why does it seem like only Hamiltonians are used in undergraduate quantum mechanics, but only Lagrangians are used in quantum field theory? garamondx ligatures no longer work How to declare a structure in a header that is to be used by multiple files in c? If I have a source.c file with a struct:  struct a {      int i;     struct b {         int j;     } };   How can this struct be used in another file (i.e. func.c)?  Should I create a new header file, declare the struct there and include that header in func.c?  Or should I define the whole struct in a header file and include that in both source.c and func.c?  How can the struct be declared extern in both files?  Should I typedef it? If so, how? I have seen many programs consisting of structures like the one below  typedef struct  {     int i;     char k; } elem;  elem user;   Why is it needed so often? Any specific reason or applicable area? My recollection is very sketchy but this is what I remember....   Film was possibly black and white I saw it as a child in the late '80s early '90s but it's older It was subtitled and in Russian or similar language It involved some astronauts  travelling in space with possibly time travel The astronauts (mostly men) encounter a planet/civilization of only women The women no longer need men to breed and are so become superior and possibly want to eliminate all men    That's all I have to go on, sorry. What is the difference between DX format and FX format lenses, and which to choose for what purpose?  What are the pros and cons of both?
