ifgt : jump if greater than zero : index : visitJumpInsn()

Description

ifgt pops the top int off the operand stack. If the int is greater than zero, execution branches to the address (pc + branchoffset), where pc is the address of the ifgt opcode in the bytecode and branchoffset is a 16-bit signed integer parameter following the ifgt opcode in the bytecode. If the int on the stack does is less than or equal to zero, execution continues at the next instruction.

If you are using Jasmin, branchoffset is computed for you from the address of <label>.

Example

    iload_1         ; push the int value in local variable 1 onto the stack
    ifgt Label      ; if the value on the stack is greater than zero, jump to Label
    return          ; return if local variable 1 is less than or equal to zero
Label:
    ; execution continues here if local variable 1 is greater than zero...

Notes

Addresses are measured in bytes from the start of the bytecode (i.e. address 0 is the first byte in the bytecode of the currently executing method).
