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 classclass 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
