Question

If I want to randomly select a letter between a and z, I assume I have to use the Random class:

Random rand = new Random();

Answer 1

why assume to use Random instead of Math.random? You can even make the code shorter...

public static char genChar(){
    return (char)(Math.random()*26 + 'a');
}
