   Primitive Data Types. A primitive data type specifies the size and type of variable values, and it has no additional methods. There are eight primitive data types in Java: Stores fractional numbers. Sufficient for storing 6 to 7 decimal digits. Stores fractional numbers. Sufficient for storing 15 to 16 decimal digits.

   An integer literal is of type long if it ends with the letter L or l; otherwise it is of type int. It is recommended that you use the upper case letter L because the lower case letter l is hard to distinguish from the digit 1. Values of the integral types byte, short, int, and long can be created from int literals. Values of type long that exceed t...

   A floating-point literal is of type float if it ends with the letter F or f; otherwise its type is double and it can optionally end with the letter D or d. The floating point types (float and double) can also be expressed using E or e (for scientific notation), F or f (32-bit float literal) and D or d (64-bit double literal; this is the default and...

   Literals of types char and String may contain any Unicode (UTF-16) characters. If your editor and file system allow it, you can use such characters directly in your code. If not, you can use a "Unicode escape" such as '\u0108' (capital C with circumflex), or "S\u00ED Se\u00F1or" (Sí Señor in Spanish). Always use 'single quotes' for char literals an...

   The eight primitive data types that are supported by Java Programming Language: byte - It is 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127. short - It is a 16-bit signed two's complement integer. It has a minimum value of -32,768 and a maximum value of 32,767.

   • int. The first primitive data type we’re going to cover is int. Also known as an integer, int type holds a wide range of non-fractional number values.
   • byte. byte is a primitive data type similar to int, except it only takes up 8 bits of memory. This is why we call it a byte. Because the memory size is so small, byte can only hold the values from -128 (-27) to 127 (27 – 1).
   • short. The next stop on our list of primitive data types in Java is short. If we want to save memory and byte is too small, we can use the type halfway between byte and int: short.
   • long. Our last primitive data type related to integers is long. long is the big brother of int. It’s stored in 64 bits of memory, so it can hold a significantly larger set of possible values.

   • boolean type. The boolean data type has two possible values, either true or false. Default value: false. They are usually used for true/false conditions.
   • byte type. The byte data type can have values from -128 to 127 (8-bit signed two's complement integer). If it's certain that the value of a variable will be within -128 to 127, then it is used instead of int to save memory.
   • short type. The short data type in Java can have values from -32768 to 32767 (16-bit signed two's complement integer). If it's certain that the value of a variable will be within -32768 and 32767, then it is used instead of other integer data types (int, long).
   • int type. The int data type can have values from -231 to 231-1 (32-bit signed two's complement integer). If you are using Java 8 or later, you can use an unsigned 32-bit integer.

   Primitive data types in Java are predefined by the Java language and named as the reserved keywords. A primitive data type does not share a state with other primitive values. Java programming language supports the following eight primitive data types. Boolean data type. byte data type. int data type. long data type.

   What is a primitive data type in Java?

   • Any data type built-in to a programming language is called primitive data type. Words primitive or built-in or basic data types are used interchangeably by authors. Primitive data types in Java are provided by the Java programming language as a basic building block and for that they are called primitive types to Java.

   What is the difference between primitive data type and object reference variable?

   • Primitive data types are not object, they just only store the actual values, whereas object reference variable store the address of the object they refer to. Primitive types are not classes, but can be used to store values like numbers and characters. Any data type built-in to a programming language is called primitive data type.

   What is the difference between primitive and object data types?

   • Let’s look at the difference between the primitive and object data types in a tabular manner as shown below as follows: Change does not reflect in the original ones. Changes reflected in the original ones if the object is mutable. Variables hold values, and every value has a specific data type that defines the kind of information it holds.

   What are primitive and reference types?

   • The primitive types [...] are the boolean type and the numeric types. The numeric types are the integral types byte, short, int, long, and char, and the floating-point types float and double. The reference types [...] are class types, interface types, and array types. There is also a special null type.

   Jul 23, 2024 · Primitive Data Type: In Java, the primitive data types are the predefined data types of Java. They specify the size and type of any standard values. Java has 8 primitive data types namely byte, short, int, long, float, double, char and boolean. When a primitive data type is stored, it is the stack that the values will be assigned.
