{
public static void main(String[] args)
{
int num;
String str = "";
Scanner sc = new Scanner(System.in);
System.out.println("Please enter the a number : ");
num = sc.nextInt();
// convert int to binary java
while(num > 0)
{
int y = num % 2;
str = y + str;
num = num / 2;

Integer.toString(100,8) // prints 144 --octal representation
Integer.toString(100,2) // prints 1100100 --binary representation
Integer.toString(100,16) //prints 64 --Hex representation
Thank you!
