I need to be able to resize a block of memory. Is
there a function in java simmilar to realloc in C ?Java memory management is completely different from C...
no untyped memory allocation is possible, so there's nothing
quite like malloc or realloc.
The closest thing there is, is to use byte arrays... and when
you need to 'resize' such an array, to allocate a new (bigger)
byte array, and then copy contents from existing one, usually using
System.arraycopy(). So, something like:
static byte[] realloc(byte[] orig, int newSize)
if (newSize <= orig.length) {
return orig;
byte [] newArray = new byte[newSize];
System.arraycopy(orig, 0, newArray, 0, orig.length);
return newArray;
