通常情况下,使用大端(Big-endian)或小端(Little-endian)表示法来存储这些字节。Java的默认字节顺序是大端。 示例代码 下面是将int转换为byte[]的示例代码。在这个例子中,我们将采用大端顺序进行存储。 publicclassIntToByteArray{publicstaticbyte[]intToByteArray(intvalue){returnnewbyte[]{(byte)(value>>24),(by...
static byte[] intArrToByteArrBigEndian() { byte[] byteArr = new byte[INT_ARRY.length * 4]; int offset = 0; for (int i = 0; i < INT_ARRY.length; i++) { int value = INT_ARRY[i]; byteArr[offset++] = (byte) (value >> 24 & 0xFF); byteArr[offset++] = (byte) (valu...
byte[] intToByteArrayLittleEndian(int x) { byte[] bytes = new byte[4]; bytes[0] = (byte) x; bytes[1] = (byte) (x >> 8); bytes[2] = (byte) (x >> 16); bytes[3] = (byte) (x >> 24); return bytes; } /** * 字节数组转int 大端模式 */ public static int byte...
记录一个int[] 转 byte[]的工具方法: publicstaticbyte[] IntArrayToByteArray(int[] intArray) {if(intArray ==null|| intArray.length == 0) {returnnull; } ByteBuffer byteBuffer= ByteBuffer.allocate(intArray.length * 4);byteBuffer.order(ByteOrder.LITTLE_ENDIAN);IntBuffer intBuffer=byteBuffer.asI...

### 基础概念 字节数组(byte array)是由字节(byte)组成的数组,通常用于存储二进制数据。整数(int)是一种基本的数据类型,用于表示数值。将字节数组转换为整数涉及到字节序(byte...
public static byte[] toLe(int i) { byte[] b = new byte[4]; b[0] = (byte) (i & 0xff); b[1] = (byte) (i >> 8 & 0xff); b[2] = (byte) (i >> 16 & 0xff); b[3] = (byte) (i >> 24 & 0xff); return b; ...
Java provides the flexibility to read data in Little Endian order through the ByteBuffer class. Let’s modify the sample code to use the native Endianness of the host machine: int value = 123456789; byte [] bytes = ByteBuffer.allocate(4).order(ByteOrder.nativeOrder()).putInt(value).array(...
public static byte[] intToByteArray(int a) { byte[] ret = new byte[4]; ret[0] = (byte) (a & 0xFF); ret[1] = (byte) ((a >> 8) & 0xFF); ret[2] = (byte) ((a >> 16) & 0xFF); ret[3] = (byte) ((a >> 24) & 0xFF); ...
