Question

I come to know that the maximum size of a method in java is 64k. And if it exceeds, we’ll get a compiler warning like “Code too large to compile”. So can we call this a drawback of java with this small amount of memory.

Can we increase this size limit or is it really possible to increase ?

Any more idea regarding this method size ?

Answer 1

In my experience the 64KB limit is only a problem for generated code. esp. when intiialising large arrays (which is done in code)

In well structured code, each method is a manageable length and is much smaller than this limit. Large pieces of data, to be loaded into arrays, can be read from a non Java files like a text or binary file.

EDIT:

It is worth nothing that the JIT won’t compile methods larger than 8 K. This means the code runs slower and can impact the GC times (as it is less efficient to search the call stack of a thread with methods which are not compiled esp big ones)

If possible you want to limit your methods to 8 K rather than 64 K.
