Working on a plugin in Java. everything works. I come to this one if statement and it just fails. I've tried changing the values from int to string and vice versa, it simply won't budge. I logged the coordinates. I try to compare them as strings. Code:  String locationx = plugin.getConfig().getString("locationx"); String eventlocationx = Integer.toString(event.getClickedBlock().getX());  String locationy = plugin.getConfig().getString("locationy"); String eventlocationy = Integer.toString(event.getClickedBlock().getY());  String locationz = plugin.getConfig().getString("locationz"); String eventlocationz = Integer.toString(event.getClickedBlock().getZ());  if (locationx == eventlocationx &amp;&amp; locationy == eventlocationy &amp;&amp; locationz == eventlocationz) {     System.out.println("SUCCESS: Passed coordinate check on the right click.");     return true; } else {     System.out.println(locationx);     System.out.println(eventlocationx);      System.out.println(locationy);     System.out.println(eventlocationy);      System.out.println(locationz);     System.out.println(eventlocationz);      System.out.println("ERROR: Failed on the right click coordinate check.");     return false; }    config:  locationx: '-226'  locationy: '64'  locationz: '266'   console log:  -226 [11:31:47 INFO]: -226 [11:31:47 INFO]: 64 [11:31:47 INFO]: 64 [11:31:47 INFO]: 266 [11:31:47 INFO]: 266 [11:31:47 INFO]: ERROR: Failed on the right click coordinate check.   I hope anyone can help me out.
I've been using the == operator in my program to compare all my strings so far. However, I ran into a bug, changed one of them into .equals() instead, and it fixed the bug.  Is == bad? When should it and should it not be used? What's the difference?
is it possible to combine two fields in one and use that field to group by in reports? for example, i would like to combine ee id and ee name fields in 1 and show as 1 field in the "group by" section on reports. How to choose a lens for my first DSLR? I am considering buying my first DSLR.  How do I know whether I need a 18-200 lens, 17-85, or 18-55? Or something else? Integration of $e^{ax}\cos bx$ and $e^{ax}\sin bx$ Types of photon qubit encoding How many types of qubit encoding on photons exist nowadays?

If column matches another file, print every line with match (awk/grep) I’m taking two input files, one with certain ID numbers, and another with a large list of ID numbers and additional columns. The latter file contains multiple lines for each ID number and I need to extract all lines that match an ID from the first file. Those lines then must be printed in a new file.

I have two LED lamps in my corridor, and when I switch them off, they keep emitting light (not very strong, but it's annoying at night).  What can it be? How can I fix it? How to prove $\lim \limits_{n\to\infty}(n+1)\int_{0}^{1}x^nf(x)dx=f(1)$ I need help to prove this in real analysis. I think it uses IMVT, but not sure how to do it.     Let $f(x)$ be a real valued continuous function on $[0,1]$. Show that   $$ \lim \limits_{n\to\infty}(n+1)\int_{0}^{1}x^nf(x)dx=f(1) $$ Line of Bones to Travel and Conform to Curve (Train or snake following path) I've searched google extensively on this. Can't seem to find an answer.   I know about spline IK, which is wonderful for conforming a row of bones to a path. But combining the armature object with a follow path modifier causes the point of origin to move, but the bones themselves stick to the beginning of curve.   Ultimately my goal is to make a creature like a snake or centipede follow a curve path, thus animating it fairly realistically ... Can I run Ubuntu OS on a Android 4.0 tablet? Windows 10 puts my first and last name to lock screen. How to avoid this? After upgrading to Windows 10, I see my LastName and FirstName on the lock screen. Is there a way to change this? On Windows 8.1 there was just my nickname and email address (maybe there were my first name and last name, but not displayed so large as they are now).  I mean the name and surname parameters specified in my Microsoft account.  Another question: I prefer the format FirstName LastName, not vice versa.  Is there any way to change this as well?   Apart from Lock Screen I see it on the Start Menu. Break a long command to multiple lines I got a shell script and inside I got the command as below #!/bin/sh sh ../jboss/bin/standalone.sh --server-config=standalone-full.xml -Djboss.node.name=node1 -b 0.0.0.0 -bmanagement 0.0.0.0  How can I break the line to multiple lines for better understanding and management #!/bin/sh sh ../jboss/bin/standalone.sh    --server-config=standalone-full.xml   -Djboss.node.name=node1   -b 0.0.0.0   -bmanagement 0.0.0.0  Tried with backslash at the end of each line and it doesnt work. if/then/else man page I would like to know if there is any man page documenting the construction of the most basic script commands like if/then/else, while, for each, and all the relative switches, like -eq, -e, -ge, and so on. Why does the question's closed status disappear when clicking to load a new edit? Why is it that when you add normally distributed random variables the variance gets larger but in the Central Limit Theorem it gets smaller? When you add two independent normal distributions the resulting distributions' variance is the sum of the variances i.e. it gets larger.  However, the Central Limit Theorem states that  when independent random variables are added, their properly normalized sum tends toward a normal distribution (informally a bell curve) even if the original variables themselves are not normally distributed.   and also says that as you add more variables the variance gets smaller. Why does the variance increase in one case but decrease in the other? Is it because in the CLT case the random variables come from the same underlying distribution? Sum of First $n$ Squares Equals $\frac{n(n+1)(2n+1)}{6}$ How do I add a non-deformed end cap to a tube? I want to create some parts that I can reuse for models. I was trying to make a steam punkish exhaust pipe. I want to be able to make the pipe of any length, and as curvy as I like but I want to keep the end cap always undeformed. I approximated my results by hand placing the "crown" at the end of this bezier curve.  I tried to make an array modifier that included the crown as the end cap, but that results in the end cap deforming.
