Class getSuperclass() method in Java with Examples
The getSuperclass() method of java.lang.Class class is used to get the super class of this entity. This entity can be a class, an array, an interface, etc. The method returns the super class of this entity.
Syntax:
public Class<T> getSuperclass()
Parameter: This method does not accept any parameter.
Return Value: This method returns the super class of this entity.
Below programs demonstrate the getSuperclass() method.
Example 1:
Java
// Java program to demonstrate getSuperclass() methodpublic class Test { public static void main(String[] args) throws ClassNotFoundException { // returns the Class object for this class Class myClass = Class.forName("Test"); System.out.println("Class represented by myClass: " + myClass.toString()); // Get the super class of myClass // using getSuperclass() method System.out.println("Superclass of myClass: " + myClass.getSuperclass()); }} |
Example 2:
Java
// Java program to demonstrate getSuperclass() methodpublic class Test { class Arr { } public static void main(String[] args) throws ClassNotFoundException { // returns the Class object for Arr Class arrClass = Arr.class; // Get the super class of arrClass // using getSuperclass() method System.out.println("Superclass of arrClass: " + arrClass.getSuperclass()); }} |
Example 3:
Java
// Demonstrate Run-Time type Information.class X{ int a; float b;}class Y extends X{double c;}class GFG{ public static void main(String args[]){ X x=new X(); Y y= new Y(); Class<?> clObj; // get class reference clObj=x.getClass(); System.out.println("a is object of type: "+ clObj.getName()); // get class reference clObj=y.getClass(); System.out.println("y is object of type: "+ clObj.getName()); clObj=clObj.getSuperclass(); System.out.println("y's superclass is: "+ clObj.getName()); }} |
Output
a is object of type: X y is object of type: Y y's superclass is: X
