Load reference from local variable
Format
aload
index
Forms
aload = 21 (0x15)
Stack
… → …, objectref
Description
The index is an unsigned byte that must be a valid index into the local variables of the current frame ( Section 3.5, Frames). The local variable at index must contain a reference. The objectref in the local variable at index is pushed onto the operand stack.
Notes
The aload instruction cannot be used to load a value of type returnAddress from a local variable onto the operand stack. This asymmetry with the astore instruction is intentional.
