Calculate the Sum, Product, Difference & Quotient in Java

By -
In this Java program, we will calculate the user inputs by Addition, multiplication, subtraction & division. The output will be displayed in Graphical User interface (GUI). 

This is the solution of Deitel & Deitel exercises 2.16:
  • Write an application that asks the user to enter two numbers from the users and prints the sum, product, difference and quotient (division) of the numbers. 
import javax.swing.*;

/**
* Exersice No.04 Display the number is larger or equal
* Created by Airgildgreat on 3/27/2017.
*/
public class DisplayLargerEqualNumbers {

public static void main(String args[]){

//Declaring the variables
String fNumber, sNumber;
int num1, num2, sum, product, diff, quo;

//Read the inputs of the user
fNumber = JOptionPane.showInputDialog("Enter the first number: ");
sNumber = JOptionPane.showInputDialog("Enter the second number: ");

//Convert the input string into integers
num1 = Integer.parseInt(fNumber);
num2 = Integer.parseInt(sNumber);

//Initialize the inputs
sum = num1 + num2;
product = num1 * num2;
diff = num1 - num2;
quo = num1 / num2;

 //Prints the result in Graphical User Interface
JOptionPane.showMessageDialog(null, "The sum is: " + sum + "\nThe product is: " + product
+ "\nThe Difference is: " + diff + "\nThe Quotient is: " + quo,"Largest and Smallest Program in GUI", JOptionPane.INFORMATION_MESSAGE);
  }
}
Here is the output. In this case assumes user input the first number "2" & second number "3"

Calculates the Squares and Cubes in Java

In this Java program, the application will display in a table the value of the squares and cubes from 1 to 10. This is the same solution of  Deitel & Deitel  exercises 2.33 in Chapter 2.  Write an application that calculates the squares and cubes of the numbers from 1 to 10 and prints the resulting values in table. public class SquareCube{ public static void main (String args[]){ //Declare the variables int square, cube, number= 1; //Dispay the header f the table System.out.printf("Number\tSquare\tCube\n"); //Loop value ntil reached no.10; while (number <= 10){ square = number * number; cube = square * number; number ++; System.out.printf(" %d\t \t%d\t \t%d\n", number, square, cube); } System.exit(0); } } Here is the output.

In this Java program, the application will determine two input numbers which is the largest, or both the numbers input are equal. This is the same solution of  Deitel & Deitel   exercise  2.17 in Chapter 2. Write an application that ask the user to enter two integers, obtains the two numbers of the user and display the larger number followed by the words "is larger" in an information message dialog. If the number are equal, print the message "These numbers are equal". public class LargerOrEqual { public static void main(String args[]){ //Declare varables String fNumber, sNumber, result; int numb1, numb2; //Read the user inputs fNumber = JOptionPane.showInputDialog("Enter first number: "); sNumber = JOptionPane.showInputDialog("Enter second number: "); //Conver input string to integer values numb1 = Integer.parseInt(fNumber); numb2 = Integer.parseInt(sNumber); result = ""; if (numb1 > numb2) result = numb...
