How Can I Generate a 16-Digit, Zero-Padded Binary String from an Integer in Java?

Zero-Padding Binary Representations in Java

To obtain a 16-digit, zero-padded binary representation of an integer in Java, consider the following approach:

Using String Manipulation:

While you've attempted using String.format, it introduces spaces for left-padding. To address this, you can replace these spaces with zeros manually:

String paddedBinary = String.format("%16s", Integer.toBinaryString(value)).replace(' ', '0');

Example:

int value = 1;
String paddedBinary = String.format("%16s", Integer.toBinaryString(value)).replace(' ', '0');

Result:

0000000000000001

Although this method is relatively straightforward, it introduces an additional step for string manipulation.
