What is java primitive data types?

Answer 1

Any data that is not stored as an object - like the integral data types (int, long, etc.), or boolean variables.

Answer 2

Basically any datatype that doesn't involve an object.

For example, int, float, double, etc., are primitive datatypes -- they are declared using the format Variable_type n = Value;, and, in general, they do not have any class functions which can be called - one cannot call n.function(), because it doesn't exist (there may be some exceptions to this, however). However, as a result, an access function is not necessary to access the variable's value -- println(n); returns value of n.

On the other hand, types such as Integer. String, etc. are not primitive datatypes, since they involve the creation and manipulation of objects. They are declared using the format Variable_type n = new Variable_type(Value);, and they tend to have some associated class functions. They do require access functions to access the variable's value -- println(n); in this case actually causes the execution of println(n.toString());, which by default returns the memory address of the object, unless otherwise overridden by the object's class definition. This access function depends from type to type.

• 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: The int data type is a 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive). For integral values, this data type is generally the default choice unless there is a reason (like the above) to choose something else. This data type will most likely be large enough for the numbers your program will use, but if you need a wider range of values, use long instead.

• long: The long data type is a 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). Use this data type when you need a range of values wider than those provided by int.

• 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 section 4.2.3of the 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 class instead.Numbers and Strings covers 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 section4.2.3 of the 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.

• boolean: The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defined.

• char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive).

Answer 4

The primitive data types in java are: byte, short, int, long, float, double, boolean, char. This just means that these types of data are not stored as objects, but as values. For anything else (like a String), you must construct an object to store value.

Answer 5

Primitive data types represent atomic values and are built into java.

Java has 8 primitive data types.

Integer Data Types

byte (1 byte)

short (2 bytes)

int (4 bytes)

long (8 bytes)

Floating Data Types

float (4 bytes)

double (8 bytes)

Character Data Types

Char (2 bytes)

Logical Data Types

boolean (1 bit) (true/false)

Answer 6

There are two types of variables in Java:

• Primitives - A primitive variable can be one of eight types: char, boolean, byte, short, int, long, double, or float. Once a primitive has been declared, its primitive type can never change, although in most cases its value can change.

• Reference variables - A reference variable is used to refer to (or access) an object. A reference variable is declared to be of a specific type and that type can never be changed.

Primitive data types are used to hold data that is used for general calculations and other similar purposes.

Primitive data types are: int, byte, float etc

Answer 7

primitive means we r changing the order of the data for further information contact

Answer 10

That refers to primitive (or simple) data types - data that is not stored in objects. This includes boolean, int, long, float and double.
