Question

In Java Write a program the takes in a number and converts it to binary. Use an OOP class approach using class and objects

Answer 1

Program:

import java.io.*;
import java.util.Scanner;
public class Test { // Here we are taking class name as Test
public static int DecimaltoBinary(int n) { // Definition of the method DecimaltoBinary
int[] Arr=new int[10]; // Here declaring the one dimensional array called Arr
int i; // Here declaring integer varaible called i
for(i=0; n>0; i++)// Loop Iteration
{
Arr[i]=n%2; // Here dividing n value with 2 and stored in Arr[]
n=n/2; // Here dividing n value with 2 and stored in n
}
for(i=i-1 ;i>=0 ;i--)// Loop Iteration
{
System.out.print(Arr[i]); // Here priting the array values
}
return Arr[i]; //Here Returning array values to the main()
} // End of method DecimaltoBinary
public static void main(String args[])throws IOException // Start of main()
{
Test ob = new Test(); // Here creating the object for class TestLeapYear
Scanner in = new Scanner(System.in);
System.out.println("Enter any Decimal Number: "); // Here taking Input from the User
int x = in.nextInt(); // Here scanning the input
System.out.print("The Binary value of "+x+ " is : ");
ob.DecimaltoBinary(x); // Here calling the DecimaltoBinary() method using object called ob
}// End of main()
} // End of class Test

Output:
