more specific replace method

[A5k]

Hi all,
I'm looking for a method like str.replace(char,char) but instead replaces only one instance of the value.

ie: String str = "java";
str = str.replace('a','x');
output > jxvx

What i'm looking for:
String str = "java";
str = str.SomeMethod('a','x');
output > jxva

Does anyone know if this exists without using StringBuffer???

an off the top of my head solution. access the String as a char array. find the first index of the character you're looking for, and set the character at that position in the char array to the string you want. I'm not completely sure, but I think that works. Liam Morley

Try this little method:

public static String replace( String str, String oldStr, String newStr )
{
int index = str.indexOf( oldStr );
String result = str.substring( 0, index ) + newStr + str.substring( index + 1, str.length() );

return( result );
}

That should do what you are looking for.

I'm pretty sure that would create new strings in memory, which is why A5k mentioned StringBuffer. Liam Morley

thanks all,
imotic, I tried that idea before posting with this type of code:

  for(int i=0;i<str.length();i++)
    charArray[i] = str.charAt(i);

But javac didn't like that idea at all. It didn't allow me to have a char within a string to be a single char?!?! Any ideas of why?

godcomplex, thanks for the code, I figured I probably had to write my own method

thanks again,
