Hi,

Here is your solution.

String str = "subodh2000";
StringBuffer strNum = new StringBuffer("");
StringBuffer strChar = new StringBuffer("");
for ( int i = 0; i < str.length(); i++ )
{
char c = str.charAt(i);
int j = (int) c;
String aChar = new Character(c).toString();
if(j>=48 && j<=57)
{
strNum.append(aChar);
}
else
{
strChar.append(aChar);
}
}

Explanation: -
---------------
You just have to go one step extra and split the string. If the current character is a number, append it to a StringBuffer (strNum). otherwise, append that character to another StringBuffer (strChar).

Hope you have understood this.

If all you need is a String with the numbers removed, you can use this...

Do you need to do something else with it?

Try this:
  • Create 3 new instances of StringBuffer. One for letters, one for numbers, and one for "other."
  • Loop through your original String one char at a time.
  • Use Character methods isLetter(char c) and isDigit(char c) to categorize each char.
  • Append the char to the appropriate StringBuffer.
  • When finished looping, convert the StringBuffers to Strings.

    Mark webber's first suggestion would be the best if you want to remove numbers from the string. i.e. you just want the non-numeric part from the given string.
