I. Types of Java data type 1. Java Shared 4 classes 8 data types

2. Value range of data types

Byte:8 bits, the maximum amount of storage data is 255, the stored data range is between -128~127.

Short:16 bits, the maximum data storage is 65536, the data range is -32768~32767.

Int:32 bits, the maximum data storage capacity is 2 of the 32-bit minus 1, the data range is negative 2 of 31 times to positive 2 square minus 31.

Long:64 bits, the maximum data storage capacity is 2 of the 64-bit minus 1, the data range is negative 2 63 times to positive 2 square minus 63.

Float:32 bit, the data range in the 3.4e-45~1.4e38, the direct assignment must be in the number after the addition of F or F.

double:64 bit, data range in 4.9e-324~1.8e308, the assignment can be added D or D can also not add.

Boolean: Only True and false two values are taken.

Char:16 bits, storing Unicode codes, and assigning values in single quotes.
