Changing a char in array.

Question

Hello!
I'm writing a program using Properties to read values from a file. But some of the keys have spaces in them, and then it will return null.
So instead I converted the string it converts it to a char array, in which i want it to change all the blank spaces to underscores, and then reassemble the array as a string. Do anyone know how to do this, or know a simpler way than mine?
Thanks in advance, TheJuice.

Do you inspect the original string object, or the one returned from the replaceAll method?
Remember that String is immutable.
Consider this:
public class TestReplace {
     public static void main(String[] args) {     
          String originalStringObject = "Text with\tWhiteSpaces";
          String replacedString = originalStringObject.replaceAll("\\s", "_");
          System.out.println(originalStringObject);
          System.out.println(replacedString);
