Last Updated : 17 Mar 2025

The getGenericSuperClass() method of java Class class returns a method object representing the specified public member method of the class or interface represented by this Class object. The name parameter is passed as a string.

Syntax

public Method getMethod(String name, Class<?>... parameterTypes)
 throws NoSuchMethodException, SecurityException

Parameter

name - the name of the method

parameterTypes - list of parameters

Returns

The Method object.

Throws

NoSuchMethodException , NullPointerException , SecurityException

Example 1

import java.lang.reflect.*;

public class ClassgetMethodExample1 {

   public static void main(String[] args) {
    
      ClassgetMethodExample1 class1 = new ClassgetMethodExample1();
      Class cls = class1.getClass();

      try {                
         Method mthd = cls.getMethod("showMethod", null);
         System.out.println("method = " + mthd.toString());        
      } catch(NoSuchMethodException e) {
         System.out.println(e.toString()); //print exception object
      }
 
      try {
         Class[] aarg = new Class[1];
         aarg[0] = Long.class;
         Method lmthd = cls.getMethod("showLongMethod", aarg);
         System.out.println("method = " + lmthd.toString());
      } catch(NoSuchMethodException e) {
         System.out.println(e.toString()); //print exception object
      }
   }

   public Integer showMethod() {
      return 1;
   }
    
   public void showLongMethod(Long lng) {
      this.lng = lng;
   }
   long lng = 788995;
}

Output:

method = public java.lang.Integer ClassgetMethodExample1.showMethod()
method = public void ClassgetMethodExample1.showLongMethod(java.lang.Long)

Example 2

//import statements?
import java.lang.reflect.Method;

public class ClassgetMethodExample2 {

    public static void main(String... args) throws NoSuchMethodException {
        Class<ClassgetMethodExample2> class1 = ClassgetMethodExample2.class;

        Method mthd = class1.getMethod("IntCalc", int.class);
        System.out.println(mthd);

        mthd = class1.getMethod("Work");
        System.out.println(mthd);

        mthd = class1.getMethod("StaticMethod", String.class);
        System.out.println(mthd);

        mthd = class1.getMethod("Work");
        System.out.println(mthd);       
    }

    public int IntCalc(int i) {return 0;}

    public void Work() {}

    public static void StaticMethod(String s) {}
}

Output:

public int ClassgetMethodExample2.IntCalc(int)
public void ClassgetMethodExample2.Work()
public static void ClassgetMethodExample2.StaticMethod(java.lang.String)
public void ClassgetMethodExample2.Work()
