Question

Java Programming

Compound Logic and nested if statement

For a student to be accepted in XYZ College, the student must meet the following requirements:

1. GPA must be 3.75 or higher.
2. Family income must be more than $60,000
3. Applicant must be a New Jersey resident.

XYZ college asked you to write a program to implement the above requirements.

1. Write the program using compound logic (AND, OR) whichever is applicable.
2. Modify the program using nested if statement.
3. This means there will be two programs written. First using compound logic(And,Or). Second, write the same program using nested if statement.
4. This means that there will be two different pseudcode for the two programs written.

Submit:

1. Source code for both version of the program
2. Output for both versions.

• Design for both versions

Answer 1

Using compound logic :

//import package
import java.util.*;

//Java class
public class CompoundLogic {
   // main() method
   public static void main(String[] args) {
       // Object of Scanner class
       Scanner sc = new Scanner(System.in);
       // asking user GPA
       System.out.print("Enter GPA : ");
       // reading GPA
       double GPA = sc.nextDouble();
       // asking user Family income
       System.out.print("Enter Family income : ");
       // reading Family income
       double familyIncome = sc.nextDouble();
       sc.nextLine();
       // asking user resident
       System.out.print("Enter resident : ");
       // reading resident
       String resident = sc.nextLine();
       //This line is using ternary operator in java
       System.out.println(GPA>=3.75 && familyIncome>60000 && resident.toUpperCase().contentEquals("NEW JERSEY")?"Student accepted to XYZ college":"Student not accepted to XYZ college");
   }

}

Output :

Screen when meets the requirements :

Screen when requirements does not meet :

using nested if statement :

//import package
import java.util.*;

//Java class
public class nestedifstatement {
   // main() method
   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);
       // asking user GPA
       System.out.print("Enter GPA : ");
       // reading GPA
       double GPA = sc.nextDouble();
       // asking user Family income
       System.out.print("Enter Family income : ");
       // reading Family income
       double familyIncome = sc.nextDouble();
       sc.nextLine();
       // asking user resident
       System.out.print("Enter resident : ");
       // reading resident
       String resident = sc.nextLine();
       // using nested of checking
       if (GPA >= 3.75) {
           // when GPS is greater then 3.75
           // checking family income
           if (familyIncome > 60000) {
               // when family income greater than 60000 then
               // checking resident
               if (resident.toUpperCase().contentEquals("NEW JERSEY")) {
                   // when resident is of New Jersey then
                   System.out.println("Student accepted to XYZ college");
               }
           }
       }

   }
