Hi,

 == operator is the equality operator

equals() is for content comparison

 == operator checks if both object references refer to the same memory location eg: if (a==b) it means it verifies whether both a and b refer to the same location in memory.

equals() if for content comparison.

eg:String a ="chandra"; String b="chandra"; String c ="radha";

if ( a.equals(b)) returns true bcoz both contains the same content.

if (a.equals(c)) returns false bcoz a and c contents are different.

 I hope this would have solved your doubt.

Thanks,

Chandra

== checks wheather two strings are pointing to same location or not.

equals method checks wheather the strings are same or not

The == operator  checks identity of
objects (that is, in a check a == b, it checks whether the two variables a
and b refer to the same object).

Wheres as .equals() compares the values...

eg-->

a="suvendu";b=a; then a==b will be true;

a="suvendu",b=new string(a); Then a==b will be false...

equals is a function in java which is used to compare strings.i.e when we want to compare names etc then we should use this.When we want to compare integer values then we can do it by ==.

( == ) is used to compare two numbers (integers, float, double) but,
.equals() is used to compare two strings.

public class Test1

{

public static void main(String args[])

{

String s1="ashu";

String s2="ashu";

if(s1==s2)                            // same Object refrence

System.out.println("H!!  first time");  


String s3 = new String("ashu");

String s4 = new String("ashu");

if(s3==s4)                              // different Objects

System.out.println("H!! Second time");
 
if(s3.equals(s4))             // this will return true as it wil check object contents

System.out.println("H!! Third Time");
}

}

the operator == compares the content of two strings
equals method compares the references of two variables

generally we use == operator for comparing numbers
