Answer:
Step-by-step explanation:
Here's a Java program that asks for the names of three runners and the time, in minutes, it took each of them to finish a race, and then displays the names of the runners in the order they finished:
import java.util.Scanner;
public class RunnerRace {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
// ask for the names of the runners and their race times
System.out.print("Enter the name of runner 1: ");
String runner1 = input.nextLine();
System.out.print("Enter the time it took runner 1 to finish (in minutes): ");
int time1 = input.nextInt();
input.nextLine();
System.out.print("Enter the name of runner 2: ");
String runner2 = input.nextLine();
System.out.print("Enter the time it took runner 2 to finish (in minutes): ");
int time2 = input.nextInt();
input.nextLine();
System.out.print("Enter the name of runner 3: ");
String runner3 = input.nextLine();
System.out.print("Enter the time it took runner 3 to finish (in minutes): ");
int time3 = input.nextInt();
input.nextLine();
// determine the order of the runners based on their race times
String firstPlace, secondPlace, thirdPlace;
int firstTime, secondTime, thirdTime;
if (time1 < time2 && time1 < time3) {
firstPlace = runner1;
firstTime = time1;
if (time2 < time3) {
secondPlace = runner2;
secondTime = time2;
thirdPlace = runner3;
thirdTime = time3;
} else {
secondPlace = runner3;
secondTime = time3;
thirdPlace = runner2;
thirdTime = time2;
}
} else if (time2 < time1 && time2 < time3) {
firstPlace = runner2;
firstTime = time2;
if (time1 < time3) {
secondPlace = runner1;
secondTime = time1;
thirdPlace = runner3;
thirdTime = time3;
} else {
secondPlace = runner3;
secondTime = time3;
thirdPlace = runner1;
thirdTime = time1;
}
} else {
firstPlace = runner3;
firstTime = time3;
if (time1 < time2) {
secondPlace = runner1;
secondTime = time1;
thirdPlace = runner2;
thirdTime = time2;
} else {
secondPlace = runner2;
secondTime = time2;
thirdPlace = runner1;
thirdTime = time1;
}
}
// display the names of the runners in the order they finished
System.out.println("First place: " + firstPlace + " (" + firstTime + " minutes)");
System.out.println("Second place: " + secondPlace + " (" + secondTime + " minutes)");
System.out.println("Third place: " + thirdPlace + " (" + thirdTime + " minutes)");
}
}
The program first asks for the names of the runners and their race times. It then determines the order of the runners based on their race times, using nested if statements to compare the race times. Finally, the program displays the names of the runners in the order they finished, along with their race times.
