Class Void in Java

Class Void in Java

The Void class may not be instantiated, and serves merely as a placeholder for its static TYPE field, which is a Class object constant that represents the void type.

The Void class is an uninstantiable wrapper for the primitive type void. The class contains simply a reference to the Class object that represents the primitive type void.

The structure of the class Void is given by

public final class java.lang.Void extends java.lang.Object {
// No Constructor
// Constants
public static final Class TYPE;
}

The details of the Void class is given as:

public static final Class TYPE;

public static final Class TYPE represents the Class object that represents the primitive type void. It is always true that Void.TYPE == void.class.

Apart from these Void class also has inherited methods from class- Object. They are as follows:

• clone()
• finalize()
• hashCode()
• notifyAll()
• wait()
• wait(long, int)
• equals(Object)
• getClass()
• notify()
• toString()
• wait(long)
