title: Declaring a binary integer constant
body: <p>So, I am implementing a DES (Data Encryption Standard) in Java and need to declare the key as a binary value of 64 bits and do not know how to do this. Could anyone help me?</p>
  
  <p>I would like to say something like this: int = K 000100110011010001010111011110011001101110111100110111111110001;</p>
  
  <p>However, the IDE always beeps error saying that it is a very large integer.</p>
