Get Super Class Name using Reflection

March 16, 2014 by Krishna Srinivasan Leave a Comment

With this example, we shall show you how to get the super class of an object and use it using the reflection technique. Lets look at the following example and the steps provided below to understand the program.

  • I have created Employee super class and its sub class Manager
  • Created instance of Manager and assigned to the super class reference Employee
  • Call getSuperclass() method of Class which returns the super class name.

Lets look at the example.

[code lang=”java”]
package javabeat.net.reflection;

public abstract class Employee {
public abstract String getName(String name);
}
package javabeat.net.reflection;

public class Manager extends Employee{
public String getName(String name){
return name;
}
}

package javabeat.net.reflection;

import java.lang.reflect.Method;

/**

*/
public class JavaBeatReflectionExample {
public static void main(String[] args) throws Exception {
// Create new object of Manager
Employee employee = new Manager();

// Get super class and display it
Class<?> classVar = employee.getClass().getSuperclass();
System.out.println("Superclass = " + classVar);
Method method = employee.getClass().getMethod("getName", String.class);
System.out.println(method.invoke(employee, "Employee Name"));
}

}

[/code]

Output

[code]
Superclass = class javabeat.net.reflection.Employee
Employee Name

[/code]
