x /= 2;
}

Console.WriteLine(num);
}
}
}

good work , perfect my friends

Answer 3

import java.util.Scanner;

public class DemicalToBinary2 {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner s = new Scanner(System.in);
System.out.println("Enter the Number = ");
int n = s.nextInt();
test2 t2 = new test2();
t2.DTB(n);
//System.out.println(Integer.toBinaryString(n));
}
}
class test2 {

void DTB(int Number) {
int[] binary = new int[25];
int index = 0;
while (Number > 0) {
binary[index++] = Number % 2;
Number = Number / 2;
}
for (int i = index - 1; i >= 0; i--) {
System.out.print(binary[i]);
}
}
}
