Java provides aByteBufferclass to do the same.to convert any byte array, first we need to wrap up using ByteBuffer’s static method wrap and then by calling getInt() method we can get integer value of that byte array. private int convertByteArrayToInt(byte[] intBytes){ ByteBuffer byteBuff...

强类型语言和弱类型语言要求变量的使用要严格符合规定,所有变量都必须先定义后才能使用 Java的数据类型分为两大类基本类型(primitive type) 引用类型(reference type)...类型转换由于Java是强类型语言,所以要进行有些运算的时候的,需要用到类型转换。...强制类型转换
