java usees wrapper classes...Byte,Integer..they are in java.lang package..\n\nin each such class there is one memeber \nstatic int SIZE\n\nusing that u can find out..\n\neg.System.out.println(Byte.SIZE);\n//The number of bits used to represent a byte value in two's complement binary form\n\nSIMILARITY FOR OTHER DATA TYPES..\n\ncheck out documentation site..or if u have already downloaded doc..then use that..

In some programs yes in some no.\n\nWhat program are you asking about?\n\n///

It is a return code from the program.  The shell that ran the program can check to see if the program exited with an error or normally.  I believe return 0 is for normal exit, and return anyother number is for an error.

it means that there is a method or function that includes a parameter (or argument) called Start.  the number you pass into that method or function must be greater than zero.\n\nmyMethod(int Start) {\n...\n}\n\n//now to call method do this\nmyMethod(1);\n\n//but don't do this\nmyMethod(0);

When variables are passed to a procedure or function they can be IN, OUT or INOUT.  An IN variable is passed into the procedure or function and is used, but can not be changed.  An OUT variable is passed to the procedure but it can be changed and left in the changed state when the procedure ends. \n\nAn INOUT variable is passed to a procedure or function, and it can be used by the block, changed by the block, and left in a “changed” state when the block ends.  A function can only be passed an IN variable and must return a variable.  If this is confusing, don’t worry.  When we get to name blocks and provide some examples it will be much cleare

Hai pankaj,\nI think the problem must be in the compilation unit(i.e, the source code).\nPlease check that your main function is syntactically correct.\nor\nCheck it with the code below.\n\nclass Hello{\npublic static void main(String []arg){\nSystem.out.println("hello");\n}\n}\n\ngood luck.

Usually means that data was delivered to the program (could be via i/o device, received via network, etc) that wasn't of an expected data type.  The program may have been expecting a number, but characters showed up.  Or maybe an integer was expected, but a date time value was received. \n\nIt's usually the result of a logic error when this occurs.

first, yahoooooo answers does not handle long lines of code, I had to view source, then extract \nSystem.out.println( testtring.replaceAll( \n     "href&#92;&#92;s*?=&#92;&#92;s*?&#92;";(.*?)&#92;",\n     "$1"));\n\nbefore I realized you shouldn't be using replaceall at all! you want to match not replace.

It's designed from the start to be platform-independent. Everything .NET (except implementation) is a public standard that can be used to recreate the runtime environment on any platform.

Hi, as of everyprogramming languge. You can input commandline arguments. In java's main method. So this is how you would do your thing:\n\n\n/**\n* This is the main method in your class\n* In this example we will get all parametres \n* and input them in the array list\n*/\npublic static void main(String[] args) {\n\n// Lets initialize the arraylist\nList mylist = new ArrayList();\n\n// Lets input the commandline arguments in the array list\nfor (int i = 0; i < args.length ; i++) {\n\n// Add to ArrayList\nmylist.add(args[i]);\n\n}\n\n// Now we finished loading all\n// the arguments in the arraylist\n// Now lets  Print the list...\n\n// Lets make a Iterator for mylist\nIterator i = mylist.iterator();\n\n// Lets traverse the List\nwhile (i.hasNext()) {\nSystem.out.println(i.next());\n}\n\n// We are done!!\nSystem.out.println("Hope I helped!!! Enjoy :D");\n}

A runtime environment provides an additional layer of abstraction between the program and the operating system. A runtime environment often runs programs using an ABI (application binary interface). As a result, they can potentially be run on any OS for which there is a runtime environment.\n\nFor example, Java programs are usually compiled to Java byte code which can then be interpreted by a Java runtime environment (JRE) on most platforms. Technically speaking, a Java program compiled to Java byte code does not run, but it is run (interpreted) by the JRE.

all types in java are signed.  that's how it was designed.  i have found it to be a problem only very rarely.

You can execute the system call of dir and pipe output to a file/string/strings and then do a search or pattern match on that.\n\nRemember u need not make system call, but this following code compiles to sufficient commands in Java class file, and JVM runtime machine will execute that instructions and makes system calls depending on OS and Environment, on behalf of user and returs the results to the hash/buffer/stack area of JVM used by that class-file/code under running. And other important thing is that there is no eazy and free way for pattern match. You might want to write your own patten matching if it were simple patterns.\n\n\nhttp://javaalmanac.com/egs/java.io/GetFiles.html?l=rel\n\n\nFor using Java's Pattern matching, u might want to do this. But for your case of searching executables, just compare last 4 characters and if it matches ".exe" then u r good to go.\n\nhttp://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
