Course: Java Programming (Oracle) (10055) > Section: Distinguishing Key Elements of Java

Use of simple data types should involve the creation of a program that declares a variable of type int, byte, short, char, long, double, float, or Boolean. Description of each variable follows:

Keyword | Description | Size/Format
 | (integers) |
byte | Byte-length integer | 8-bit two's complement
short | Short integer | 16-bit two's complement
int | Integer | 32-bit two's complement
long | Long integer | 64-bit two's complement
 | (real numbers) |
float | Single-precision floating point | 32-bit IEEE 754
double | Double-precision floating point | 64-bit IEEE 754
 | (other types) |
char | A single character | 16-bit Unicode character
Boolean | A Boolean value (true or false) | true or false
