Making one big String with the same char

Question

I need to generate a String which represents only one char n-times.
Something like:
String str = new String(char Source, int iRepeat)
String str = new String('x', 5);
str = 'xxxxx';
Thanks in advance!

Answer 1

public String createString(char c, int n) {
  StringBuffer sb = new StringBuffer();
  for ( int y=0; y <= n; y++ ) {
     sb.append(c);
  return sb.toString();
}that should work.
always use string buffers when youre appending text. when you change the value of a STRING object, the jvm actually creates a new string in memory, and just changes the reference to the new string (since each variable you declare as STRING is actually just a reference). this isnt a problem with small strings, but if you create a string thats fairly large, youll notice a huge performance difference. so, just use Strings for storing values, and StringBuffers for string values you plan on changing often.
