Subtract String from String

Question

I have a string 1.2 sec or say 0.4 sec What I am trying to do is simple, just remove sec from the end of the string. I want to do it in just one line. I know the other ways, convert to char array search for space and delete and all after that but I was wondering if this could be done like "1.2 sec" - " sec" or like time - " sec" or something like that but just in a line or two. If there isn't then I know how to do it. But if there is how?

Update:

If I execute this code:

String time = stopwatch1.getjLabel4text();
String replace = time.replace(" sec","");
System.out.println(replace+"");
System.out.println(time+"");

I get output:

2.0 Sec
2.0 Sec

Answer 1

Say the string is stored in s, you could use s.replaceAll(" Sec","") to remove it.

Answer 2

You can do

    String str = "1.2 sec";
    String requiredString = str.substring(0,str.indexOf('s')).trim();
