Java Method equals() Method

The equals () method of Method class compares this method against the specified object and returns true if both are same.

Syntax

Parameter

obj - the reference object with which to compare.

Returns

true if these objects are same; false otherwise.

Throw

No exception is thrown.

Example 1

//import statements

 import java.lang.annotation.Retention;
 import java.lang.annotation.RetentionPolicy;
import java.lang.reflect.Method;

public class ReflectMethodequalsExample1  {

   public static void main(String[] args) {

      Method[] mthd = equalsDemoClass1.class.getMethods();
      boolean isequal = mthd[0].equals(mthd[1]);
      System.out.println("Methods are " + (isequal?"equal.":"not equal."));
   }
}

class equalsDemoClass1 {
   private String data1 ;
   private String data2 ;

   public equalsDemoClass1(){
   }

   public equalsDemoClass1(String data1){
      this.data1 = data1;
   }

   public String getData() {
      return data1;
   }

   public void setdata(String  data1) {
      this.data1 = data1;
   }

   public String getData2() {
      return data2;
   }

   public void setdata2(String data2) {
      this.data2 = data2;
   } 
}

Output:

Methods are not equal.

Example 2

import java.lang.reflect.Method; 
  
public class ReflectMethodequalsExample2 { 
  
    public static void main(String[] args) 
        throws NoSuchMethodException, 
               SecurityException, 
               ClassNotFoundException 
    { 
  
       
        Method[] mthd = DemoClassNo1.class.getMethods(); 
  
        Method mthd2 = DemoClassNo1.class.getMethod("adddata", String.class); 
  
        System.out.println("First Method object from array :::::" +mthd[0]); 
        System.out.println("Method object created by :::::"  + mthd2); 
  
        if (mthd[0].equals(mthd2)) { 
            System.out.println("Both Method objects  are equal"); 
        } 
        else { 
            System.out.println("Both Method objects  are not equal"); 
        } 
    } 
} 
  

class DemoClassNo1 { 
  
    private String data1; 
  
    public DemoClassNo1 () 
    { 
    } 
  
    public String adddata(String data2) 
    { 
        return this.data1 + data2; 
    } 
}

Test it Now

Output:

First Method object from array :::::public java.lang.String DemoClassNo1.adddata(java.lang.String)
Method object created by :::::public java.lang.String DemoClassNo1.adddata(java.lang.String)
Both Method objects  are equal
