How can trailing whitespace be removed from a byte array in Java?

edit

One way to remove trailing whitespace from a byte array in Java is to use the trim() method of the String class. This can be done as follows:

byte[] originalBytes = ...; // the original byte array
String str = new String(originalBytes).trim();
byte[] trimmedBytes = str.getBytes();

Explanation:

1. Convert the byte array to a string using the String(byte[]) constructor.
2. Use the trim() method to remove the trailing whitespace from the string.
3. Convert the resulting string back to a byte array using the getBytes() method. The resulting byte array will not contain trailing whitespace.
