Answer:
Here the code is given as follows,
Explanation:
Code:
import java.util.Scanner;
//created class named largeintegers
class largeintegers{
//class can hold a long number
long number;
//constructor to set number
largeintegers(long number){
this.number=number;
}
//getNumber method to get number
long getNumber(){
return number;
}
//below are some basic operations
long addition(long num1,long num2){
return num1+num2;
}
long subtract(long num1,long num2){
return num1-num2;
}
long multiply(long num1,long num2){
return num1*num2;
}
boolean compare(long num1,long num2)
{
return num1>num2;
}
public static void main(String[] args) {
//declared to long numbers
long number1,number2;
//scanner class to take user input
Scanner sc= new Scanner(System.in);
//taking input numbers
System.out.println("Enter a Number ");
number1=sc.nextLong();
System.out.println("Enter 2nd Number :");
number2=sc.nextLong();
//created two objects
largeintegers object=new largeintegers(number1);
largeintegers object2=new largeintegers(number2);
//displaying two numbers
System.out.println("Entered Numbers ");
System.out.println(object.getNumber());
System.out.println(object2.getNumber());
//calling basic methods using created objects
System.out.println("Some Operations on Given two Numbers ");
System.out.println("Addition:"+object.addition(object.getNumber(), object2.getNumber()));
System.out.println("Subtraction:"+object.subtract(object.getNumber(), object2.getNumber()));
System.out.println("Multiplication:"+object.multiply(object.getNumber(), object2.getNumber()));
System.out.println("Comparison:");
if(object.compare(object.getNumber(), object2.getNumber())==true)
{
System.out.println("First Number is Greater than Second Number ");
}
else
{
System.out.println("Second Number is Greater than First Number ");
}
sc.close();
}
}
Output:-
Answer:
a) Planning chart:
Create the form, and add two buttons, calculate and exit, and add two labels and two textboxes, as shown in the second image. Now code the buttons as shown in the image file, and debug. The required program is ready.
b) The design is as shown in the second image,
c) And the code for the windows form is also ready. Steps in brief. Open visual studio, Go to file menu and hit on New. Now choose Windows form from project type, and give the project name VB2017/chap02. Now code as explained in A, and as explained in images.
D) We just need to follow the plan to build the interface.
E) The code of exit button. Double click exit button to enter code-behind, and add this.Close(); And that's it, we have the project ready.
Explanation:
Please check the answer section.
And If you want Rounded off value, then you need to all below code in calc_click method. Double click on calc, and code behind will appear. Add the below code over there:
double tax = Convert.ToDouble((textBox1.Text)) * 5/100;
double Roundedtax = Math.Round(tax, 2);
textBox2.Text = Convert.ToString(Roundedtax);
textBox2.Show();
textBox3.Text = Convert.ToString(Convert.ToDouble(textBox1.Text) + Convert.ToDouble(textBox2.Text));
textBox3.Show();
For dollar sign, add a label after each textbox, and change its text to $s.
