Java: How does the == operator work when comparing int?

Question

Given this Java code:

int fst = 5;
int snd = 6;

if(fst == snd)
    do something;

I want to know how Java will compare equality for this case. Will it use an XOR operation to check equality?

Answer 1

Are you asking "what native machine code does this turn into?"? If so, the answer is "implementation-depdendent".

However, if you want to know what JVM bytecode is used, just take a look at the resulting .class file (use e.g. javap to disassemble it).
