String Replace??

Is there a function in the Java API to replace strings ? There are methods in the String and StringBuffer objects to replace a single character, but is there any such method for replacing an entire string?

.

Look into method like getString() or StringBuffer() will give u some clue on that...

myString.Replace('a',b');

I searched the Java Language API for JDK 1.2.2 and have found nothing in the String or the StringBuffer class that can give me a clue.

Daok, excuse me, but I have said already that I need a function to replace strings, and not individual characters.

.

Here y'go honeybee, add this puppy to your class:

Code:

---

  /**
  * General purpose utility for searching and replacing strings
  */
  public String replace(String source, String find, String replace) {
    // bail if nothing to look for or replace
    String retval = "";
    if((find.length() == 0) ||
      ((replace.length() == 0))) return source;               
      StringTokenizer st = new StringTokenizer(source, find, true);
      try {
        while(st.hasMoreTokens()) {       
        String token = st.nextToken();
        retval += token.equals(find) ? replace : token;
      }
    } catch(Exception e) { // shouldn't happen }       
  }
    return retval;
  }

:o sigh.... here is some code that works...

Code:

---

Public class Test {
        Public static void main(String[] args) {
                System.out.println(Test.replaceStr("ThisABCisABCaABCtest", "ABC", " "));
        }

        Public static String replaceStr(String replace, String oldStr, String newStr) {
                While (replace.indexOf(oldStr) != -1) {
                        replace = replace.substring(0, replace.indexOf(oldStr)) +
                                newStr + replace.substring(replace.indexOf(oldStr) + oldStr.length());
                }
                return replace;
        }       
}
