Explanation:

import java.util.*;

class Dec_to_bin

{

public static void main(string args[])

Scanner sc=new Scanner(System.in());

System.out.println("enter a number");

int n=sc.nextInt();

String s=""

while (n>0)

{

if(n%2==0)

s="0"+s;

else

s="1"+s;

n/=2;

}

System.out.println("the binary form is"+s);

}
