Java Reflection Part I

Java Reflection Example

Reference: http://tutorials.jenkov.com/java-reflection/index.html

Here is a quick Java Reflection example to show you what using reflection looks like:

Test.java

public class Test {

private String a;

private Integer b;

public Test(String a, Integer b) {

super();

this.a = a;

this.b = b;

}

public String getA() {

return a;

}

public void setA(String a) {

this.a = a;

}

public Integer getB() {

return b;

}

public void setB(Integer b) {

this.b = b;

}

}

     This example obtains the Class object from the class called Test. Using the class object the example gets a list of the methods in that class, iterates the methods and print out their names.
Exactly how all this works is explained in further detail throughout the rest of this tutorial (in other texts). 

Mainmethod2.java

public class Mainmethod2 {

public static void main(String[] args) {

// TODO Auto-generated method stub

Method[] methods = Test.class.getMethods();

for(Method method : methods){

   System.out.println("method = " + method.getName());

}

}

} 

o/p:

method = getA

method = setA

method = getB

method = setB

method = wait

method = wait

method = wait

method = equals

method = toString

method = hashCode

method = getClass

method = notify

method = notifyAll
