Question

• Using the Scanner class to obtain input from the user. • Using printf to output information to the user. • Using arithmetic operators to perform calculations. • Using if statements to make decisions based on the truth or falsity of a condition. • Using relational operators to compare variable values. Project 1: Write an application that asks the user to enter two integers, obtains them from the user and prints their sum, product, difference and quotient (division). Sample Output: CSC 110 Lab 4 Page 1 of 3 Project 2. Write an application that asks the user to enter two integers, obtains them from the user and displays the larger number followed by the words “is larger”. If the numbers are equal, print the message “These numbers are equal”

Answer 1

import java.util.Scanner;

public class Larger {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter 2 numbers: ");
       // reading 2 numbers
       int n1 = sc.nextInt();
       int n2 = sc.nextInt();
       // printing sum and difference and product and division
       System.out.println("Sum : " + (n1 + n2));
       System.out.println("Difference: " + (n1 - n2));
       System.out.println("Product : " + (n1 * n2));
       System.out.println("Div : " + (n1 / n2));
       // checking which one is larger and printing its details
       if (n1 > n2) {
           System.out.println(n1 + " is larger");
       } else if (n2 > n1) {
           System.out.println(n2 + " is larger");
       } else {
           System.out.println("Both are equal");
       }
   }
}
