Description

sipush takes a single parameter, <n> (a 16-bit signed integer), sign extends it to a 32-bit int, and pushes the resulting int onto the operand stack.

sipush is typically more efficient than ldc. It also occupies fewer bytes in the class file.

Example

 sipush    0x10    ; push the value 0x10 (16)                   ; onto the operand stack 

Bytecode

The sipush opcode is followed in the bytecode by a 16-bit signed short specifying the integer value to push.
