Question

Please answer all the questions and I don't want work for another person. do it in jaf project.

5.6 (Conversion from m to kilometers) Write a program that displays the following two tables side by side: Miles Miles Kilometers Kilometers 1.609 20 12.430 15.538 3.218 25 37.290 14.481 60 I 65 40.398 10 16.090 5.8 (Find the highest score) Write a program that prompts the user to enter the number of students and each student's name and score, and finally displays the name of the student with the highest score. Use the next method in the Scanner class to read a name rather using the nextLine method

Answer 1

public class MilesToKilometers
{
   public static void main(String[] args)
   {
       System.out.printf("%-12s%-12s %s   %-12s%-12s\n",
               "Miles", "Kilometers", "|", "Kilometers", "Miles");
       int miles = 1;
       int kilometers = 20;
       while (miles <= 10)
       {
           System.out.printf("%-12s%-12.3f %s   %-12d%-12.3f\n",
                   miles, (double)miles * 1.609, "|",
                   kilometers, (double)kilometers / 1.609);
           miles++;
           kilometers = kilometers + 5;
