How Can I Get a 0-Padded Binary String Representation of an Integer in Java?

Obtaining 0-Padded Binary Representations of Integers in Java

In Java, the task of obtaining a 0-padded binary representation of an integer may require specific formatting techniques. One common approach is to rely on the Integer.toBinaryString method, which converts an integer into a binary representation. However, simply using this method will result in spaces being added for left-padding.

To obtain the desired 0-padding, an alternative method is required. One approach is to use the String.format method with a custom format specifier. The following code demonstrates this approach:

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

In this example, the s format specifier ensures that the result will be a string consisting of 16 characters. The Integer.toBinaryString(1) part converts the integer 1 into its binary representation, which will be a shorter string than 16 characters. By replacing the spaces with '0' characters using the replace method, we obtain the desired 0-padded binary representation.
