replaceall - Java Remove Dash In String Array

Currently I am trying to remove dash in my string array. The code that I tried below didn't work.

splitTimeStamp[0].replaceAll("[\\s\\-()]", "");
System.out.println(splitTimeStamp[0]);

Got the replaceAll code from another stackoverflow page.

Thanks in advance!

Answer

The method returns a new String. The original one isn't changed.
You need to save the result like this

splitTimeStamp[0] = splitTimeStamp[0].replaceAll("[\\s\\-()]", "");
System.out.println(splitTimeStamp[0]);
