使用流将字节数组转换为整型数组

byte[] byteArray = {0, 0, 0, 1, 0, 0, 0, 2, 0, 0, 0, 3};
int[] intArray = new int[byteArray.length / 4];

try {
    ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArray);
    DataInputStream dataInputStream = new DataInputStream(byteArrayInputStream);

    for (int i = 0; i < intArray.length; i++) {
        intArray[i] = dataInputStream.readInt();
    }

    dataInputStream.close();
    byteArrayInputStream.close();
} catch (IOException e) {
    e.printStackTrace();
}

// 输出整型数组的值
for (int i : intArray) {
    System.out.println(i);
}
