How Can I Convert Strings to and from Hexadecimal in Java?

Converting Strings to Hexadecimal in Java

Working with hexadecimal values is often encountered when dealing with low-level programming operations. This includes scenarios like creating checksums, manipulating binary data, and interfacing with hardware devices. Java provides a straightforward way to convert strings into their hexadecimal representations.

To convert a string like "testing123" into hexadecimal, you can leverage Java's BigInteger class. The following code snippet illustrates how this is achieved:

public String toHex(String arg) {
    return String.format("%040x", new BigInteger(1, arg.getBytes(/*YOUR_CHARSET?*/)));
}

The toHex method takes a string as an argument and returns its hexadecimal representation. The String.format method is employed to ensure that the resulting hexadecimal string has a fixed length of 40 characters (in this example).

Regarding converting the hexadecimal value back to a string, the process is similar but in reverse. You can use the BigInteger class's toString method to convert the hexadecimal representation back into a string.

public String fromHex(String arg) {
    return new String(new BigInteger(arg, 16).toByteArray());
}

The fromHex method assumes that the input string represents a valid hexadecimal value. It converts the hexadecimal string back into an array of bytes using the toByteArray method and then constructs a string from these bytes.

This provides a convenient way to work with hexadecimal values in Java, ensuring smooth handling of data in its raw form.
