 * @author javawithease
 */
class TestString{
	String str1 = "www.javawithease.com";
	String str2;
 
	/**
	 * This method is used to show the use of intern() method.
	 * @author javawithease
	 */
	public void internTest(){
		str2 = str1.intern();
		System.out.println(str2);
	}
}
 
public class StringInternExample {
	public static void main(String args[]){
		//creating TestString object
		TestString obj = new TestString();
 
		//method call
		obj.internTest();
