Correct way to trim a string in Java

Question

In Java, I am doing this to trim a string:

String input = \" some Thing \";
System.out.println(\"before->>\"+input+\"<<-\");
input = input.trim(         


        

Answer 1

Yes, but there will still be two objects until the garbage collector removes the original value that input was pointing to. Strings in Java are immutable. Here is a good explanation: Immutability of Strings in Java.
