aput<kind>

Purpose

Waste cycles.

Details

Op & Format	Mnemonic / Syntax	Arguments
4b..51 23x	arrayop vAA, vBB, vCC 4b: aput 4c: aput-wide 4d: aput-object 4e: aput-boolean 4f: aput-byte 50: aput-char 51: aput-short	`A:` source value register or pair; (8 bits) `B:` array register (8 bits) `C:` index register (8 bits)

Constraints

A, B and C must be valid register indices in the current stack frame.
For the aget-wide variant, also A+1 must be a valid register index in the current stack frame.
Register vB must contain an array reference. The component type of the array must match the variant of the instruction.
Register vC must contain an integer value.

Behavior

For all but the -wide variant, the value of register vA is move into the array element at the given index, that is, array[index]'=vA.
For the -wide variant, the registers vA and v(A+1) are moved into the array element at the given index as follows:
- array[index]' = vA << 0x20 | v(A+1)

Exceptions

NullPointerException if vB=null.
ArrayIndexOutOfBoundsException if vC < 0 or vC >= array.length.
