Primitive data types and Wrapper Classes

Primitive data types

• byte
• short
• int
• long
• float
• double
• boolean
• char

Wrapper Classes

• Byte
• Short
• Integer
• Long
• Float
• Double
• Boolean
• Character

Autoboxing and Unboxing

• Autoboxing is the automatic conversion that the Java compiler makes between the primitive types and their corresponding
• object wrapper classes. For example, converting an int to an Integer, a double to a Double, and so on. If the conversion
• goes the other way, this is called unboxing.
• The following table lists the primitive types and their corresponding wrapper classes, which are used by the Java compiler
• for autoboxing and unboxing:

Primitive Type	Wrapper Class
boolean	Boolean
char	Character
byte	Byte
short	Short
int	Integer
long	Long
float	Float
double	Double
