Size. If you think about Java int is the same as a number, you might be right or wrong because in programming it about to memory allocation particular variables. But char is an exception; it is unsigned and consumes 2 bytes in memory. It is important to note that Java does not support unsigned types. The actual data stored in the char data type does not take up more than 8 bits . Stores positive and negative numbers ranging from -2,147,483,648 to 2,147,483,647. Java Mai 2 Types Ke Data Type Hote Hain. } Note: In addition to primitive data types, there are also referenced types (object type). In this tutorial we discussed Java's primitive or basic data types their default values and range. Stores positive and negative numbers ranging from -32,768 to 32,767. This values can be either be positive or negative. The eight primitive data types supported by the Java programming language are: byte : The byte data type is an 8-bit signed two's complement integer. text-align: center; System.out.println("Value Declared using Byte Data Type is  " + byteData); It stores the value that ranges from -32,768 to 32767. public static void main(String[] args) { All primitive or basic data types hold numeric data that is directly understood by system.
