String Replace??

[honeybee]

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...

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:

  /**
   * 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;
  }

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

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;
	}	
}
