Removing whitespace from strings in Java

Question

I have a string like this:

mysz = \"name=john age=13 year=2001\";

I want to remove the whitespaces in the string. I tried trim()

Answer 1

public static void main(String[] args) {        
    String s = "name=john age=13 year=2001";
    String t = s.replaceAll(" ", "");
    System.out.println("s: " + s + ", t: " + t);
}

Output:
s: name=john age=13 year=2001, t: name=johnage=13year=2001
