How do you test code that uses ByteBuffer and CharBuffer?

Testing code that uses ByteBuffer and CharBuffer effectively can help ensure that data is correctly read and written in byte and character formats. Here’s a simple example illustrating how to use these buffers in Java:

// Importing necessary classes import java.nio.ByteBuffer; import java.nio.CharBuffer; public class BufferExample { public static void main(String[] args) { // Create a ByteBuffer ByteBuffer byteBuffer = ByteBuffer.allocate(10); byteBuffer.put((byte) 'H'); byteBuffer.put((byte) 'i'); // Prepare ByteBuffer for reading byteBuffer.flip(); // Convert ByteBuffer to CharBuffer CharBuffer charBuffer = CharBuffer.allocate(10); while (byteBuffer.hasRemaining()) { charBuffer.put((char) byteBuffer.get()); } // Prepare CharBuffer for reading charBuffer.flip(); // Print characters from CharBuffer while (charBuffer.hasRemaining()) { System.out.print(charBuffer.get()); } } }
