Description

Retrieves the long integer stored in local variables <n> and <n> + 1 and pushes it onto the operand stack. Both <n> and <n> + 1 must be valid local variable numbers in the current frame, and together they must be holding a long.

See the description of lstore for more information on how doubles are retrieved from local variables.

'lstore_<n>' is functionally equivalent to 'lstore <n>', although it is typically more efficient and also takes fewer bytes in the bytecode.

Example

 lstore_0        ;store long in local variable 0 and 1 lstore_1        ;store long in local variable 1 and 2 lstore_2        ;store long in local variable 2 and 3 lstore_3        ;store long in local variable 3 and 4 

Bytecode

Type	Description
u1	lstore_0 opcode = 0x3F (63)
u1	lstore_1 opcode = 0x40 (64)
u1	lstore_2 opcode = 0x41 (65)
u1	lstore_3 opcode = 0x42 (66)
