When you say String is immutable, what do you mean by that?
Say I have String s = "Ness"
s= s+"Technologies";
What will happen? If the value gets appended, then what is
the meaning of immutable here?

Answer Posted / anjani kumar jha
Now u add s= s+"Technologies";
so it will NessTechnologies because you append. and assign
new varible,means that new addition is assigned to s
take one example for more clarity
String x = "Java";
x.concat(" Rules!");
System.out.println(x);
output is x=java
because string is immutable.............think hard on it
Consider the following another example---------and think
about that
public class NewClass {
public static void main(String as[])
{
String s="abc";
String s1=s+"cde";
System.out.println(s);
System.out.println(s1);
String x = "Java";
x.concat(" Rules!");
System.out.println(x);
}
}
output is
s=abc;
s1=abcde
x=java
since u have added cde in s but still from the output it is
abc...............means string is immutable,
