They can be broadly categorized into Primitive Data Types and Reference/Object Data Types. -------------------------------------------------- Primitive Data Types Primitive data types are predefined by the language and are named by a keyword. They are the simplest forms of data types and include: byte short int long float double char boolean 1. byte Size: 1 byte (8 bits) Range: -128 to 127 Description: Stores small integer values. Useful for saving memory in large arrays. Example: java Copy code public class Main { public static void main(String[] args) { byte num = 100; System.out.println("Byte value: " + num); } } 2. short Size: 2 bytes (16 bits) Range: -32,768 to 32,767 Description: Stores integer values. It is also used to save memory as it is smaller than int. Example: java Copy code public class Main { public static void main(String[] args) { short num = 30000; System.out.println("Short value: " + num); } } 3. int Size: 4 bytes (32 bits) Range: -2^31 to 2^31 - 1 (i.e., -2,147,483,648 to 2,147,483,647) Description: Default data type for integer values. Example: java Copy code public class Main { public static void main(String[] args) { int num = 100000; System.out.println("Int value: " + num); } } 4. long Size: 8 bytes (64 bits) Range: -2^63 to 2^63 - 1 (i.e., -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807) Description: Used for large integer values beyond the range of int. Example: java Copy code public class Main { public static void main(String[] args) { long num = 10000000000L; // 'L' at the end is necessary to denote a long value System.out.println("Long value: " + num); } } 5. float Size: 4 bytes (32 bits) Range: Approximately ±3.40282347E+38F (6-7 decimal digits precision) Description: Used for single-precision floating-point numbers (decimal values). Use F to denote a float. Example: java Copy code public class Main { public static void main(String[] args) { float num = 3.14F; // 'F' is needed to denote a float literal System.out.println("Float value: " + num); } } 6. double Size: 8 bytes (64 bits) Range: Approximately ±1.79769313486231570E+308 (15 decimal digits precision) Description: Used for double-precision floating-point numbers. It is the default type for decimal values. Example: java Copy code public class Main { public static void main(String[] args) { double num = 3.14159; System.out.println("Double value: " + num); } } 7. char Size: 2 bytes (16 bits) Range: 0 to 65,535 (Unicode values) Description: Stores a single 16-bit Unicode character. Used to store any character (letter, number, symbol). Example: java Copy code public class Main { public static void main(String[] args) { char letter = 'A'; System.out.println("Char value: " + letter); } } 8. boolean Size: 1 bit (theoretically, but in reality, it might take up more space depending on JVM implementation) Range: true or false Description: Used to store logical values (true or false). Example: java Copy code public class Main { public static void main(String[] args) { boolean isJavaFun = true; System.out.println("Boolean value: " + isJavaFun); } } --------------------------------------------- Copyright Disclaimer under Section 52 of the Copyright Act, 1957 (India): This video is made for educational, informational, and entertainment purposes only.
