Is there an existing class in Java wherein I can use just say create 50 spaces and start displaying a string in the text Area?

I don't like to create a method that just loop and create a space with append the string I want.

You probably need this to set the initial size of the TextArea, instead of just filling in spaces, you can also use the methods: setColumns(int), be sure to read the API doc of the setColumns(int) and getColumnWidth() as setting the number of columns is not the same as allowing for n characters.

If you still want to use spaces, there is no ready made class, I would do the loop, though make sure you don't loop on a String (way too slow and creates a ton of temporary string objects), use StringBuffer:

StringBuffer s = new StringBuffer();
for (int i = 0; i < 50; i++) {
  s.append(" ");
}
String finalString = s.toString();


of course you can make this more efficient by adding 2 or more spaces at a time, its just supposed to be an example

This should be a bit faster:

char[] spaces = new char[50];
Arrays.fill(spaces, ' ');
String s = new String(spaces);

Hi,

I think this would be the fastest ;-)

String Str = new String("                                                 ");

Uday.
