Question

Write a program in java processing.

Write a program that does the following: · Assume the canvas size of 500X500. · The program asks the user to enter a 3 digit number. · The program then checks the value of the first and last digit of the number. · If the first and last digits are even, it makes the background green and displays the three digit number at the mouse pointer. · If the two digits are odd, it makes the background red and displays the three digit number at the mouse pointer. · If the first digit is odd and the third is even, it makes the background blue and display the three digit number at the mouse pointer. · The number entered by the user is displayed at the mouse pointer at all times irrespective of the location of the mouse pointer.

Answer 1

import javax.swing.JOptionPane;

int number;

color c;

void setup(){

size(500,500);

//asking, reading number

number=Integer.parseInt(JOptionPane.showInputDialog("Enter a three digit number: "));

//assuming user will always enter a valid three digit number

//fetching first digit by integer division of number by 100

int first=number/100;

//fetching last digit by modulo division by 10

int last=number%10;

//if first and last digits are even, assigning green color to c

if(first%2==0 && last%2==0){

c=color(0,255,0);

}

//if first and last digits are odd, assigning red color to c

else if(first%2!=0 && last%2!=0){

c=color(255,0,0);

}

//if first digit is odd and last digits is even, assigning blue color to c

else if(first%2!=0 && last%2==0){

c=color(0,0,255);

}

//there is still one more case which is not mentioned in the question, that is

//if first digit is even and second is odd, since not specified any other, I'm

//using a default gray color

else{

c=color(200,200,200);

}

}

void draw(){

//using c as background color

background(c);

//using black fill color

fill(0);

//drawing number at mouse position

text(""+number,mouseX,mouseY);

}
