thnks hardwired. a small question how can i fixe the output if the names enter some are biger than other so it can print the scores in aliment some like this
peter............60
marco paulo...80

Run through the names and get the length of the longest name. When you print each name add the number of
spaces = longestNameLength - thisNameLength + whateverExtra;
after the name and before printing the score. You can make up a method to return the spaces

Code:

private int space(int n) {
    for(int j = 0; j < n; j++)
        s += " ";
    return s;
}
