Write a program that prompts the user to enter two characters and display the corresponding major and year status. The first cha

nydimaria [60]

Answer:

import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter two characters: ");
String inputStr = input.nextLine();
if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
System.out.println("Biology");
}
else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
System.out.println("Computer Science");
}
else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
{
System.out.println("Information Technology and Systems");
}
else{
System.out.println("Invalid major");
}
int num = Character.getNumericValue(inputStr.charAt(1));
if(num >= 1 && num <= 4){
switch (num){
case 1:
System.out.println("freshman");
break;
case 2:
System.out.println("sophomore");
break;
case 3:
System.out.println("junior");
break;
case 4:
System.out.println("senior");
break;
}
}
else{
System.out.println("Invalid year status");
}
}
}

Explanation:

The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.

The part 2 is to validate the year status to make sure it only fall within the range of 1-4 (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.

Blank Are input instructions you give to a computer

kotegsom [21]

Explanation:

A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse. The processing of input to output is directed by the software but performed by the hardware.
