Java's ByteBuffer class provides a straightforward way to convert a byte array to an integer. Here’s how to do it: public class BytesToIntWithByteBuffer { public static void main(String[] args) { byte [] byteArray = { 0x01, 0x02, 0x03, 0x04 }; // Example byte array . ByteBuffer buffer = ByteBuffer. wrap (byteArray);
2 lut 2024 · To convert a byte array to an integer, we can use the wrap method to create a ByteBuffer instance and then call the getInt method to interpret the bytes as an integer. Let’s see how we can convert a byte array to an integer using ByteBuffer: System.out.println("Converted Integer Value: " + intValue); } }
