    Anyone know what's the difference between BIPUSH and SIPUSH when it comes to Opcodes?

    From Opcodes Class:
    Code:
        public static final int BIPUSH = 16;
        public static final int SIPUSH = 17;
    Don't tell me 16 and 17, I see that. I want to know what each is used for.
    Thanks

    BIPUSH pushes a signed byte onto the stack. SIPUSH pushes a signed short onto the stack.

    A simple search through the JVM specification would've told you that.

    For future reference, try Java bytecode instruction listings - Wikipedia, the free encyclopedia

    It doesn't take long to get a general idea of what each instruction does.
