Java Basic Types

The Java language provides eight basic types. Six types of numbers (four integers, two floating-point types), one character type, and one Boolean type.
1, integers: including int,short,byte,long
2. Float Type: float,double
3, Character: Char
4, Boolean: Boolean

Basic type	Size	Minimum value	Maximum Value
Boolean	1-bit	-----	------
Char	16-bit	Unicode 0	Unicode 2^16-1
Byte	8-bit	-128	+127
Short	16-bit	-2^15	+2^15-1
Int	32-bit	-2^31	+2^31-1
Long	64-bit	-2^63	+2^63-1
Float	32-bit	IEEE754	IEEE754
Double	64-bit	IEEE754	IEEE754
void

(1) bit (bit): A bit is the smallest unit of data stored in a computer, which refers to a number of bits in a binary number with a value of "0" or "1". (2) Bytes: bytes are the basic unit of computer storage capacity, and one byte consists of a 8-bit binary number. Inside a computer, a byte can represent a data, or it can represent an English letter, and two bytes can represent a single character. 1024 bytes are called 1K bytes (1KB), 1024K bytes are called 1 megabytes (1MB), and 1024M bytes are called 1 gigabytes (1GB).
