How Can I Customize Binary String Padding in Java?

Customizing Binary String Padding in Java

In Java, the Integer.toBinaryString() method converts an integer into its binary representation as a string. However, by default, the leading spaces are added for padding. This can be undesirable when you need zero-padded binary strings.

One way to achieve zero-padding is to use a custom Formatter pattern:

This pattern ensures that the binary string is exactly 16 characters long, with leading zeros added as necessary.

Alternatively, you can use the following approach:

This method takes the default binary string, removes any spaces, and replaces them with zeros. While less elegant than the Formatter pattern, it is a viable option if you prefer a more straightforward approach.
