- `byte`: The `byte` data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The `byte` data type can be useful for saving memory in large arrays, where the memory savings actually matters. They can also be used in place of `int` where their limits help to clarify your code; the fact that a variable's range is limited can serve as a form of documentation.
- `short`: The `short` data type is a 16-bit signed two's complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive). As with `byte`, the same guidelines apply: you can use a short to save memory in large arrays, in situations where the memory savings actually matters.
- `int`: By default, the `int` data type is a 32-bit signed two's complement integer, which has a minimum value of -231 and a maximum value of 231-1. In Java SE 8 and later, you can use the `int` data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 232-1. Use the [`Integer`](javadoc:Integer) class to use `int` data type as an unsigned integer. See the section [The Number Classes](id:lang.numbers_strings.numbers) for more information. Static methods like [`compareUnsigned()`](javadoc:Integer.compareUnsigned(int,int)) have been added to the [`Integer`](javadoc:Integer) class to support the arithmetic operations for unsigned integers.
-- `long`: The `long` data type is a 64-bit two's complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the `long` data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1. Use this data type when you need a range of values wider than those provided by `int`. The [`Long`](javadoc:Long) class also contains methods like [`compareUnsigned()`](javadoc:Long.compareUnsigned(int,int)), [`divideUnsigned()`](javadoc:Long.divideUnsigned(int,int)) etc to support arithmetic operations for unsigned long.

- `float`: The `float` data type is a single-precision 32-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in the [Floating-Point Types, Formats, and Values](doc:floating-point-types) section of the [Java Language Specification](doc:java-language-specification). As with the recommendations for `byte` and `short`, use a `float` (instead of `double`) if you need to save memory in large arrays of floating point numbers. This data type should never be used for precise values, such as currency. For that, you will need to use the [`java.math.BigDecimal`](javadoc:BigDecimal) class instead. [Numbers and Strings](id:lang.numbers_strings) covers [`BigDecimal`](javadoc:BigDecimal) and other useful classes provided by the Java platform.
- `double`: The `double` data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in the [Floating-Point Types, Formats, and Values](doc:floating-point-types) section of the [Java Language Specification](doc:java-language-specification). For decimal values, this data type is generally the default choice. As mentioned above, this data type should never be used for precise values, such as currency.
