lconst_<l>

push the long integer 0 or 1

Jasmin Syntax

     lconst_0 or     lconst_1 

Stack

Before	After
...	<l>-word1
	<l>-word2
	...

Description

lconst_<l> represents the two opcodes lconst_0, lconst_1 that are used to push the constant long integers 0 and 1 onto the stack. For example, to push the long integer zero onto the stack, use:

     lconst_0 ; push long integer 0 onto the stack 

Note that you could also use:

     ldc2_w 0    ; push the long integer 0 onto the stack 

although this instruction takes more space in the class file and is also slower.

Example

 lconst_0    ; push the long int 0 onto the stack lconst_1    ; push the long int 1 onto the stack 

Bytecode

Type	Description
u1	lconst_0 opcode = 0x09 (9)
u1	lconst_1 opcode = 0x0A (10)
