The toString() method is one of the feature of java. It is the method of class String which is imported default on JVM from java.lang.Object;

ToString() method is one of the display method.

When ever we tries to print the text from System.out.println("Hello"); then it directly inherit from the toString() method. We can override the toString() method and make the println to print what we desire.

For eg.

[sourcecode=’java’]public class Student{
private String name;
private String ssn;
public Student(String dName, String dSsn){
//set value to accessor method of private attributes
//accessor method…..
public String toString(){
return “Student Name : ” +this.getName()+”nSsn : ”
+ this.getSsn();

//main method
public static void main(String[] args){
//let create a object
Student s1 = new Student(“Narayan”, “12345”);
/*this is the line where we can print without
defining any method but on jvm it is really
inheriting with toString() method to display
