Answer / anilkumar
"==" is used to evaluate whether tht two objects are of same type or not.
Eg: A a1=new A();
A a2=new A();
A a3=a1;
a1==a2 returns false, because a1 reference and a2 reference are not same.
a3==a1 returns true because a3 reference is pointing to a1.
"equals()" compares the contents of objects.
Eg:A a1=new A(10);
A a2=new A(10);
A a4=new A(20);
a1.equals(a2) returns true because both contents are same.
a1.equals(a4) returns false because their contents are different.

Answer / chanchal verma
== compares the reference values whether they are pointing to the same object or not. equals() method compares the contents of two objects.
Ex.
String s1=new String("chanchal");
String s2=new String("chanchal");
System.out.println(s1==s2);// prints false
System.out.println(s1.equals(s2));

Answer / ramanareddy333
equal method compare the the content of the strings,where
as == compares the referance variables .
for example
string s1 = 'ramana'
string s2= ' ramana'
if(s1==s2)
s.o.p("s1, s2 are same");
else
s.o.p(" s1, s2 are not same");
ans = s1,s2 are not same because == compares the referance
variables.
