Method Class | getName() Method in Java

Last Updated : 05 Dec, 2018

The getName() method of java.lang.reflect.Method class is helpful to get the name of methods, as a String. To get name of all methods of a class, get all the methods of that class object. Then call getName() on those method objects.

Syntax:

public String getName()

Return Value: It returns the name of the method, as String.

Example:

  Method:public void getValue(){}  getName() returns: getValue  Explanation: The getName() function on object of above method returns name of method  which is getValue.    Method:public void paint(){}  getName() returns: paint

Below programs illustrates getName() method of Method class:

Example 1: Print name of all methods of Method Object.

   /* 
* Program Demonstrate how to apply getName() method 
* of Method Class. 
*/
import java.lang.reflect.Method; 
  
public class GFG { 
  
    // Main method 
    public static void main(String[] args) 
    { 
  
        try { 
            // create class object 
            Class classobj = GFG.class; 
  
            // get list of methods 
            Method[] methods = classobj.getMethods(); 
  
            // get the name of every method present in the list 
            for (Method method : methods) { 
  
                String MethodName = method.getName(); 
                System.out.println("Name of the method: "
                                   + MethodName); 
            } 
        } 
        catch (Exception e) { 
            e.printStackTrace(); 
        } 
    } 
  
    // method name setValue 
    public static int setValue() 
    { 
        System.out.println("setValue"); 
        return 24; 
    } 
  
    // method name getValue 
    public String getValue() 
    { 
        System.out.println("getValue"); 
        return "getValue"; 
    } 
  
    // method name setManyValues 
    public void setManyValues() 
    { 
        System.out.println("setManyValues"); 
    } 
} 
 
  

Output:

  Name of the method: main  Name of the method: getValue  Name of the method: setValue  Name of the method: setManyValues  Name of the method: wait  Name of the method: wait  Name of the method: wait  Name of the method: equals  Name of the method: toString  Name of the method: hashCode  Name of the method: getClass  Name of the method: notify  Name of the method: notifyAll

Example 2: Program to check whether class contains a certain specific method.

   /* 
* Program Demonstrate how to apply getName() method 
* of Method Class within a class 
*/
import java.lang.reflect.Method; 
  
public class GFG { 
  
    // Main method 
    public static void main(String[] args) 
    { 
  
        String checkMethod = "method1"; 
  
        try { 
            // create class object 
            Class classobj = democlass.class; 
  
            // get list of methods 
            Method[] methods = classobj.getMethods(); 
  
            // get the name of every method present in the list 
            for (Method method : methods) { 
  
                String MethodName = method.getName(); 
                if (MethodName.equals(checkMethod)) { 
                    System.out.println("Class Object Contains"
                                       + " Method whose name is "
                                       + MethodName); 
                } 
            } 
        } 
        catch (Exception e) { 
            e.printStackTrace(); 
        } 
    } 
} 
// a simple class 
class democlass { 
  
    public int method1() 
    { 
        return 24; 
    } 
  
    public String method2() 
    { 
        return "Happy hours"; 
    } 
  
    public void method3() 
    { 
        System.out.println("Happy hours"); 
    } 
} 
 
  

Output:

  Class Object Contains Method whose name is method1
