The invoke() method is used to call public method in java using reflection API.
Example
TestClass.java
package com.w3spoint; public class TestClass { public void display(String message){ System.out.println(message); } } |
ReflectionTest.java
package com.w3spoint; import java.lang.reflect.Method; public class ReflectionTest { public static void main(String args[]){ try { TestClass testClass = new TestClass(); Class c=Class.forName("com.w3spoint.TestClass"); Method method = c.getMethod("display", String.class); method.invoke(testClass, "Hello w3spoint"); } catch (Exception e) { e.printStackTrace(); } } } |
Output
Hello w3spoint |
