 {
 BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
 Decimal2binary call = new Decimal2binary();
 System.out.print("Enter a decimal number : ");
 int n = Integer.parseInt(br.readLine());
 System.out.print("Binary Equivalent : ");
 call.dectobin(n);
 System.out.print("\n");
 }
 void dectobin(int n)
 {
 int c;
 if(n!=0)
 {
  c=n%2;
  dectobin(n/2);
  System.out.print(c);
 }
 }
}
