Digital Typically, when we work with numbers, we use the original data type, such as byte,int,long,double. Example int i = 5000; float GPA = 13.65; byte mask = 0xaf; However, in development, we encounter situations where objects need to be used rather than the original data type. To implement this, Java provides a wrapper class for each raw data type. All wrapper classes (Integer, Long, Byte, Double, Float, short) are subclasses of th
