This Java program prompts the user to input their scores for three tests, calculates the average by adding the scores and dividing by three, and displays the average score to the user. It uses Scanner to get user input for each test score, calculates the average by summing the scores and dividing by three, and prints out the average.

1. import java.util.Scanner;
public class TestAverage
{
public static void main(String a[])
{
double testScore1;
double testScore2;
double testScore3;
double average;
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter your first test score: ");
testScore1 = keyboard.nextDouble();
System.out.println("Enter your second test score: ");
testScore2 = keyboard.nextDouble();
System.out.println("Enter your third test score: ");
testScore3 = keyboard.nextDouble();
average = (testScore1 + testScore2 + testScore3) / 3.0;
System.out.println("Your average score is: " + average);
System.exit(0);
}
