In Java, I am doing this to trim a string:
String input = " some Thing ";
System.out.println("before->>"+input+"<<-");
input = input.trim();
System.out.println("after->>"+input+"<<-");
Output is:
before->> some Thing <<-
after->>some Thing<<-
Works. But I wonder if by assigning a variable to itself, I am doing the right thing. I don't want to waste resources by creating another variable and assigning the trimmed value to it. I would like to perform the trim in-place.
So am I doing this right?
