onto stack
Bytecode
Type | Description |
u1 | aconst_null opcode = 0x01 (1) |
Push the special null
object reference
onto the operand
stack. null is a reference to no object, and has no type (null
can be
cast to any reference type). null
conventionally represents an invalid or
uncreated object. Fields, variables and the elements of object reference arrays have null
as their initial value.
The Java Virtual Machine does not mandate a concrete value for null
.
