// Print the random letter to the console.// Liang Java 10th edition. Pg 87, Listing 3.3 // This is an example of how to make a random number. // int number1 = (int)(Math.random()*10);
// Liang Java 10th edition. Pg 125, Table 4.4 // We can map from integers to Capital letters // Characters ‘A’ to ‘Z’ have a Value in Decimal of 65 to 90.
// Liang Java 10th edition. Pg 122, 4.2.5 the random method. // a + Math.random() * b // returns a random number between a and a+b, excluding a+b.
