3 java questions: debugging, templating and Swing app for Texts cleansing

// __ how do you debug debug:
~
Exception in thread "main" java.lang.OutOfMemoryError: Java heap
space
~
kinds of errors?
~
// __ How can you make this method taking in an array on ints and
enlarging it, make the same thing for long[]('s), byte[]('s) in fact
any possible array.
~
// __ (((iAr != null) && ((iArL = iAr.length) > 0)) || (iNwL > 0))
public int[] _enlargeIntArr(int[] iAr, int iNwL) throws
InputContextException{
boolean Is = false;
int[] iNwAr = null;
int iArL;
// __
if((iAr != null) && ((iArL = iAr.length) > 0)){
if(iNwL > iArL){
iNwAr = new int[iNwL];
System.arraycopy(iAr, 0 , iNwAr, 0, iNwL);
iAr = null;
System.gc();
}// (iNwL > iArL)
else{
String aX = "// __ New Length must be greater than previous one.
iNwL: |" + iNwL + "|, iArL: |" + iArL + "|";
throw new InputContextException(aX);
}
}// ((iAr != null) && ((iArL = iAr.length) > 0))
else if(iNwL > 0){ iNwAr = new int[iNwL]; }
else{
String aX = "// __ New Length must be greater than 0. iNwL: |" +
iNwL + "|";
throw new InputContextException(aX);
}
// __
return(iNwAr);
}

// __ Do you know of any swing application to compare two text files,
partially programatically, partially by eyeballing them?
The j app. should syncronize teh scrolling of both texts to that the
same section would be visible even if you scroll one of them

There are heap profilers out there which will tell you what objects
are allocated.

You can't really... Java Generics are not like C++ Templates. They may
have a similar appearance, but their functionality is quite different
except in the most basic cases. If you need to support multiple types
of arrays of primitives, you have to manually support it.

I don't know about a swing application specifically, but there are
plenty of graphical diff programs available. google is your friend.
