What is toString() method?
Returns a string representation of an(y) object. The toString() method returns a string that textually represents this object.
The toString method for any Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
package org.javatutorials.StringBased; public class Employee { private String firstName; private String lastName; private int age; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public static void main(String[] args) { Employee emp = new Employee(); emp.setFirstName("Kelly"); emp.setLastName("Scott"); emp.setAge(40); System.out.println(emp); } }
Output
org.javatutorials.StringBased.Employee@6ae6235dOverriding toString() method yields desired and more readable output of the object.
