Question

Write a program that simulates a simple calculator. It reads two integers and a character. If the character is a +, the sum is printed; if it is a -, the difference is printed; if it is a *, the product is printed; if it is a /, the quotient is printed; and if it is a %, the remainder is printed.

In the 2- dimensional plane, a point is described by its two coordinates x and y. It supports these operations :

A constructor allowing initialization of both coordinates

Accessors and mutators to its coordinates

Translation of a point

Write a java class, called MyPoint, that corresponds to such an abstraction of points in the dimensional plane.

Provide a tester class that creates one point, then translates and displays its new coordinates.

Explanation / Answer

SIMPLE CALCULATOR

import java.util.Scanner;

public class cal {
    /**
     * @param args
     */
    public static void main(String[] args) {
        double press;
        double n1, n2;
        String operation;
        Scanner scannerObject = new Scanner(System.in);

        do{
        System.out.println("Enter first number");
        n1 = scannerObject. nextDouble();

        System.out.println("Enter second number");
        n2 = scannerObject. nextDouble();

        Scanner op = new Scanner(System.in);
        System.out.println("Enter your operation");
        operation = op.next();

        switch (operation) {
        case "+":
            System.out.println("Your answer is " + (n1 + n2));
            break;

        case "-":
            System.out.println("Your answer is " + (n1 - n2));
            break;

        case "/":
            System.out.println("Your answer is " + (n1 / n2));
            break;

        case "*":
            System.out.println("Your asnwer is " + (n1 * n2));
            break;

        default:
            System.out.println("Invalid Operation");

        }
        System.out.println("Plz press 1 for continue Otherwise press 0");
        press=scannerObject. nextDouble();
    }while(press==1);
    }
}

2- dimensional plane, a point

import java.util.Scanner;

    public class Point {

    private double x;
    private double y;

    public Point(double x, double y) {
        this.x = x;
        this.y = y;
    }

    public double getX() {
        return x;
    }

    public double getY() {
        return y;
    }

    @Override
    public String toString() {
        return "(" + this.x + "," + this.y + ")";
    }
   
}

public class Test

{

public static void main(String[] args){
    Point point= new Point(3,2);
            System.out.println(point.toString());
    }

}
