The following table lists all Java primitive data types, their storage requirements in bytes and the numeric range they support. In java we have two categories of data type: 1) Primitive data types 2) Non-primitive data types – Arrays and Strings are non-primitive data types, we will discuss them later in the coming tutorials. In this tutorial we discussed Java's primitive or basic data types their default values and range. char charData = 'A';     // declaring character data type They specify the size and type of any standard values. In Java, all data types variables must first be declared before they can be used. The eight primitives defined in Java are : boolean, byte, short, int, long, float, double, and char.These types directly contains the value of that type, and serve as the building blocks of data manipulation in Java. This type of data type is designed in order to store decimal numbers. Primitive data types are predefined by the java language itself. Let us now look into the eight primitive data types in detail. This values can be either be positive or negative. There are eight primitive data types in Java: Data Type.

By default, the int data type is a 32-bit signed two’s complement integer, which has a minimum value of -2^31 and a maximum value of 2^31–1. But char is an exception; it is unsigned and consumes 2 bytes in memory. The above article explains java primitive data types in detail with examples and significance of each data type. Primitive Data types in java are those data types that specify type and size of data but does not provide any additional methods, examples of primitive data types available in java include byte, short, int, char, long, float, boolean and double. The actual data stored in the char data type does not take up more than 8 bits . Primitive data are only single values and have no special capabilities. Java Mai 2 Types Ke Data Type Hote Hain. So Number further has divided into data types like int, long, double float, etc. System.out.println("Value Declared using Boolean Data Type is  " + booleanData); Primitive Data Types. margin: 0; Primitive data type are fixed size in nature means the variable with primitive data type is allocated a fixed size of memory and they do not contain any additional methods. Stores Decimal numbers. Size of these 8 primitive data types wont change from one OS to other. System.out.println("Value Declared using Integer Data Type is  " + intData); However, leaving class members uninitialized is not considered a good practice. Size. Stores whole numbers from -128 to 127. short. When a primitive data type is stored, it is the stack that the values will be assigned to. Java has 8 primitive data types namely byte, short, int, long, float, double, char and Boolean. char is a primitive data type in Java . It includes byte, short, int and long which are for whole-valued signed numbers. When a variable is declared local to a function it must be initialized or assigned before its first use otherwise compiler reports an error "variable might not have been initialized". Below is the syntax showing how primitive data types are used in java: byte byteData= 88;  //declaring byte data type } All primitive or basic data types hold numeric data that is directly understood by system. The data types represent type of data, the data types can be used in variable declaration and return type of a method. Non-Primitive Data Types … Primitive Data Types. color: #fff; public static void main(String[] args) { Java primitive data types are the basic data types that are built-in to Java language. Note #3: Though the variables aren’t declared gets a default value by the compiler, there is a scope for variables, called local, and is dangerous not to initialize them in that scope, because the comp… programming tutorials and interview questions, Java: The Complete Reference, Seventh Edition. double doubleData = 29.94d;    // declaring double data type There are 8 primitive data types: . 1. boolean: boolean data type represents only one bit of information either true or false, but the size of the boolean data type is virtual machine-dependent.Values of type boolean are not converted implicitly or explicitly (with casts) to any other type. The size of the long data type is 64bit/8byte. Java primitive data types are initialized to some default values when they are declared as class members. }. Java is a case-sensitive language so it is recommended use “L” in upper case. In that case class members are initialized to some default values by the compiler. Primitive data types; Non - primitive data types; 1. Stores positive and negative numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. The following table lists the default values for Java's primitive data types shown in Table 1. Jab Bhi Aap Kisi Value Ko Store Karne Ke Liye Variable Create Karte Hai To Aap Sath Hi Us Variable ka Data type Bhi Define Karte Hai | Data Type Se Compiler Ko Ye Pta Chalta Hai Ki Is Variable Mei Kis Type Ka Data Store Kiya Jayega | It has a minimum value of … int type. Considering size and type of data, java has defined eight types of primitive data type. long longData = 20000000000000L;  // declaring long data type System.out.println("Value Declared using Character Data Type is  " + charData); Related Article: Java Data Types Tutorial – Java Tutorial For Beginners.
