Real example of toString() method in java.

class ToStringEx1
{
int rollno;
String name;
String city;
 
ToStringEx1(int rollno, String name, String city)
{
this.rollno=rollno;
this.name=name;
this.city=city;
}

public String toString()
{
return rollno+" "+name+" "+city;
}
 
public static void main(String surat[])
{
ToStringEx1 s1=new ToStringEx1(1,"Mahi","Surat");
ToStringEx1 s2=new ToStringEx1(2,"Kinjal","Ahmedabad");
   
System.out.println(s1);//compiler writes here s1.toString()
System.out.println(s2);//compiler writes here s2.toString()
}
}

Output:
