java - equals method not returning expected o/p -

please solve doubt equals(). think equlas() checks content in following example should print true because content same of both t1 , t2, prints false. why?

public class test {         public static void main(string args[]) {                 test1 t1 = new test1(10);                 test1 t2 = new test1(10);                 system.out.println(t1.equals(t2));         } }  class test1 {         int ;         test1( int x){                 = x ;         } } 

thanks in advance

you need override equals in test1 class desired behavior. otherwise, class inherit equals object, determines if 2 references refer same object. here, have different instances, false result.

quoting linked javadocs:

the equals method class object implements discriminating possible equivalence relation on objects; is, non-null reference values x , y, method returns true if , if x , y refer same object (x == y has value true).

typically test if other object of same class, compare individual field(s) equality.
