Doubt with String method "replace"

[Gitesh Ramchandani]

What is the output (Assuming written inside main)
String s1 = new String("amit");
System.out.println(s1.replace('m','r'));
System.out.println(s1);
String s3="arit";
String s4="arit";
String s2 = s1.replace('m','r'); //WHY false?
System.out.println(s2==s3);
System.out.println(s3==s4);

Ans:
arit
amit
false
true

My doubt: Why is this false String s2 = s1.replace('m','r');
s1.replace('m','r') will create a new string "arit" which already exists in the string pool (which is s2), so why are we getting a false.

pls help,
regards,
gitesh

public class IO
{
public static void main(String args[])
{
String s1 = new String("amit");
System.out.println(s1.replace('m','r'));
System.out.println(s1);
String s3="arit";
String s4="arit";
String s2 = s1.replace('m','r'); //WHY false?
System.out.println(s2);
System.out.println(s2.equals(s3));
System.out.println(s3==s4);

}
}
output:
arit
amit
arit
true
true

Just analyze the above example then you can understand the concept

[raghu nagabandi]

here s1 is runtime object not compile time object.
so it is giving false.

i came to understand two things:

1. s1.replace() is a run-time object.
2. If i have String s="gitesh";

and String s1="gitess";
String s2=s.replace('h','s');

then s2 will not point to the s1 string in the string pool, instead will create a new string "gitess", because "gitess" is not present at compile-time.

Is my understanding correct?
