JAVA PROGRAMMING

A bank charges a base fee of $10 per month, plus the following check fees for a commercial checking account:

$.10 each for less than 20 checks

$.08 each for 20-39 checks

$.06 each for 40-59 checks

$.04 each for 60 or more checks.

Write a JAVA program that asks for the number of checks written for the month. The program should then calculate and display the bank's service fees for the month.

B)

Write a JAVA program that asks the user to enter three names, and then displays the names sorted in ascending order. For example, if the user entered in "Charlie", "Leslie", and "Andy", the program would display:

Andy

Charlie

Leslie

import java.util.Scanner; // Needed for the Scanner class

public class Chpt3Number7 {
   public static void main(String [] args)    {
       String name1, name2, name3, temp;

       // Create a Scanner object to read input.
       Scanner keyboard = new Scanner(System.in);

       System.out.print("What is the first name? ");
       name1 = keyboard.nextLine();

       System.out.print("What is the second name? ");
       name2 = keyboard.nextLine();

       System.out.print("What is the third name? ");
       name3 = keyboard.nextLine();

       if (name1.charAt(0) > name2.charAt(0)) {
           temp = name1;
           name1 = name2;
           name2 = temp;
       }

       if (name1.charAt(0) > name3.charAt(0)) {
           temp = name1;
           name1 = name3;

       System.out.println(name1);
       System.out.println(name2);
       System.out.println(name3);

   }
}
