whats the difference between == and .equal ?
Answer Posted / manoj kumar sahu(secon pvt.ltd
In java if u use the .equal method it will compare the two
value if the values are match with each other the result
will give true otherwise false.
But if u use == it will compare the reference(address
of)two values.
s1 = new String("abc");
s2 = new String("abc");
Now, if you use the "equals()" method to check for their
equivalence as
if(s1.equals(s2))
System.out.println("s1.equals(s2) is TRUE");
else
System.out.println("s1.equals(s2) is FALSE");
it will give the output TRUE
let's try using '=='
if(s1==s2)
System.out.printlln("s1==s2 is TRUE");
else
System.out.println("s1==s2 is FALSE");
Now you will get the FALSE as output because both s1 and s2
are pointing to two different objects even though both of
them share the same string content. It is because of 'new
String()' everytime a new object is created.
if u try with out using new keyword the output will TRUE.
