Write a program to display a random choice from a set of six choices for breakfast
(you could use any set—for example, scrambled eggs, waffles, fruit, cereal, toast, or yogurt).
Output of Above Java Program
Breakfast choice is yogurt
(you could use any set—for example, scrambled eggs, waffles, fruit, cereal, toast, or yogurt).
public class Choice {
public static void main(String args[]) {
// Use an integer to determine the choice:
int myChoice = 0;
// Select a random value for myChoice between 0 and 5:
myChoice = (int)(6.0*Math.random());
// The above line ensures each integer from 0 to 5 is equiprobable.
// Multiplying the value produced by random() by 6.0 results in a value
// from 0.0 to 5.99999
// Values from 0 to 0.99999 becomes 0, from 1.00 to 1.99999 becomes 1,
// and so on, with values from 5.0 to 5.99999 becoming 5.
// Print the appropriate Breakfast Choice depending on value myChoice:
switch(myChoice) {
case 0:
System.out.println("Breakfast choice is scrambled eggs");
break;
case 1:
System.out.println("Breakfast choice is waffles");
break;
case 2:
System.out.println("Breakfast choice is fruit");
break;
case 3:
System.out.println("Breakfast choice is cereal");
break;
case 4:
System.out.println("Breakfast choice is toast");
break;
case 5:
System.out.println("Breakfast choice is yogurt");
break;
}
}
}
Output of Above Java Program
Breakfast choice is yogurt
