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" );     } } |
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" );     } } |
Class Object Contains Method whose name is method1
