How to use toString() method

toString() Method in object class:

•Object class contains toString method that may be overridden by other classes.

•If you pass an object to print*method, toString method is called implicitly.

•When you override toString method, it must return a string, that usually contain fields name with their values.

•Its good practice to override this method

Syntax and with Example:

//Student class

/**

 *

 * @author usman

 */

public class Student {

      int id;

     String name;

    @Override

    public String toString() {

        return "Student{" + "id=" + id + ", name=" + name + '}';

    }

    

    

}

//TestClass

/**

 *

 * @author usman

 */

public class TestClass {

    /**

     * @param args the command line arguments

     */

    public static void main(String[] args) {

        Student student = new Student();

        student.id = 10;

        student.name = "Hashmi";

        System.out.println(student);

        System.out.println(student.toString());

    }

    

}
