Create new object

Stack 

... -> ..., objectref 

Description 

The unsigned indexbyte1 and indexbyte2 are used to construct an index into the constant pool of the current package ([[3.5_Frames| Section 3.5, Frames]]), where the value of the index is (indexbyte1 << 8) | indexbyte2. The item at that index in the constant pool must be of type CONSTANT_Classref ([[6.7.1_CONSTANT_Classref| Section 6.7.1, CONSTANT_Classref]]), a reference to a class or interface type. The reference is resolved and must result in a class type (it must not result in an interface type). Memory for a new instance of that class is allocated from the heap, and the instance variables of the new object are initialized to their default initial values. The objectref, a reference to the instance, is pushed onto the operand stack. 

Notes 

The new instruction does not completely create a new instance; instance creation is not completed until an instance initialization method has been invoked on the uninitialized instance.
