Long variables are stored as signed 64-bit (8-byte) integers ranging in value from -9,223,372,036,854,775,808 through 9,223,372,036,854,775,807.

sizeof(datatype)
Not without casting. A char is a 16 bit type, whereas a byte is an 8 bit type. Therefore the compiler cannot guarantee that the 16 bit value will fit into the 8 bit value without overflowing. If you attempt to stick a char into a byte, you will get a compiler error. To override this, you can cast the char value to a byte during assignment. However, you might get some unexpected results. A few examples below: char a = 'A'; byte b = a; //compiler error char a = 'A'; byte b = (byte)a; //valid, no error. b=65 char a = 172; byte b = (byte)a; //valid, no error, but b=-84 because of overflow.
While there are obvious data types like primitives (boolean, char, byte, short, int, long, float, double) and arrays, really any class which stores some form of information can be considered a data type. Objects like String, BigInteger, and the whole Collections framework also belong in this category.
It is used to convert the value of one datatype into a value of another datatype. Example- Integer.parseInt(in.readLine); It converts given value to Integer datatype.

Any datatype which the user creates in code, that isn't native to the language. A linked list can be an example of this
