Try the following:
String randText = Integer.toString((int)(Math.random() * Integer.MAX_VALUE), 36);

Here is a web page which describes a decent function also:

This one will make a random string of upper case letters of your choice

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		 int achar;
		 char i;
		 String randomKey = "";
		 for(int y = 0; y < 10; y++)
		 achar = 65 + (int)((Math.random() * Integer.MAX_VALUE)%26);
		 i = (char)achar;
		 randomKey = randomKey + i;
