Here is a Java Program to Convert an integer into binary, hexadecimal, and octal.

class StringConversions {
  public static void main(String args[]) {
    int num = 19648;

    System.out.println(num + " in binary: " +
                       Integer.toBinaryString(num));

    System.out.println(num + " in octal: " +
                       Integer.toOctalString(num));

    System.out.println(num + " in hexadecimal: " +
                       Integer.toHexString(num));
  }
}

Output of Above Java Program
19648 in binary: 100110011000000
19648 in octal: 46300
