Stack ... ..., objectref

Description The unsigned indexbyte1 and indexbyte2 are used to construct an index into the constant pool of the current class (§3.6), where the value of the index is (indexbyte1 << 8) | indexbyte2. The item at that index in the constant pool must be a CONSTANT_Class (§4.4.1). The symbolic reference is resolved (§5.1) and must result in a class type (it must not result in an array or interface type). Memory for a new instance of that class is allocated from the garbage-collected heap, and the instance variables of the new object are initialized to their default initial values (§2.5.1). The objectref, a reference to the instance, is pushed onto the operand stack.

Linking Exceptions During resolution of the CONSTANT_Class constant pool item, any of the exceptions documented in §5.1 can be thrown.

Otherwise, if the CONSTANT_Class constant pool item re-solves to an interface or is an abstract class, new throws an InstantiationError.

Otherwise, if the current class does not have permission to access the resolved class (§2.7.8), new throws an IllegalAccessError.

Note 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.
