Let us see these eight primitive data types in detail.
byte
Byte data type is an 8-bit
Minimum range is -128 (-2^7)
Maximum range is 127 (inclusive)(2^7 -1)
Default value is 0
Example: byte age = 35
short
Short data type is a 16-bit
Minimum range is -32,768 (-2^15)
Maximum range is 32,767 (inclusive) (2^15 -1)
Default value is 0.
Example: short empId = 10000
int
int data type is a 32-bit
Minimum range is – 2,147,483,648 (-2^31)
Maximum range is 2,147,483,647(inclusive) (2^31 -1)
The default value is 0
Example: int customerId = 100000
long
Long data type is a 64-bit
Minimum range is -9,223,372,036,854,775,808(-2^63)
Maximum range is 9,223,372,036,854,775,807 (inclusive)(2^63 -1)
Default value is 0L
Example: long productId = 100000L
float
Float data type is a single-precision 32-bit
Default value is 0.0f
Example: float price = 234.5f
double
double data type is a double-precision 64-bit
Default value is 0.0d
Example: double currencyRate = 123.4
boolean
boolean data type represents one bit of information
boolean will hold only two possible values that are: true and false
Default value is false
Example: boolean status = true
char
char data type is a single 16-bit Unicode character
Minimum range is ‘\u0000’ (or 0)
Maximum range is ‘\uffff’ (or 65,535 inclusive)
Example: char letter = ‘A’
