Java reflection get method modifier value


The java.lang.Class provides the methods to examine the runtime properties of the object including its members and type information. For every type of object, the JVM instantiates an immutable instance of java.lang.Class. Using reflection, we can get the metadata of a class at run time.

The getMethod() is used to get public method in java. It takes method name and parameter types of the method.

The getModifiers() method is used to get method modifier value in java.

Example

TestClass.java

package com.codesjava;
 
public class TestClass {
	public void display(String message){
		System.out.println(message);
	}
}

ReflectionTest.java

package com.codesjava;
 
import java.lang.reflect.Method;
import java.lang.reflect.Modifier;
 
public class ReflectionTest {
	public static void main(String args[]){
		try {
			Class c=Class.forName("com.codesjava.TestClass");  
			Method method = c.getMethod("display", String.class);
			System.out.println("Modifier Type: " + Modifier.toString(method.getModifiers()));
		} catch (Exception e) {
			e.printStackTrace();
		}  
	}
}

Output

Modifier Type: public
