Data Types


Some Data Types are : 

    
Int   :   Stores integers (whole numbers), without decimals. Example: 123, -456.
    
Float    :   Stores floating-point numbers, with decimals. Example: 3.14, -1.5.
    
Char    :   Stores a single character. Example: 'A', 'b'.
    
String    :   Stores a sequence of characters. Example: "Hello".
    
Boolean    :   Stores a value of either true or false.
    
Double   :   Stores double-precision floating-point numbers. Example: 19.99, -11.11.
    
Short   :   Stores smaller integers, ranging from -32,768 to 32,767.
    
Long    :   Stores large integers. Example: 123456789L.




Syntax Example:

int num = 100;



Program Example for Each Data Type

INPUT


public class DataTypesExample {
    public static void main(String[] args) {
        // Integer
        int num = 100;
        System.out.println("Integer: " + num);

        // Float
        float decimalNumber = 10.5f;
        System.out.println("Float: " + decimalNumber);

        // Character
        char letter = 'A';
        System.out.println("Character: " + letter);

        // String
        String message = "Hello World";
        System.out.println("String: " + message);

        // Boolean
        boolean flag = true;
        System.out.println("Boolean: " + flag);

        // Double
        double largeDecimalNumber = 19.99;
        System.out.println("Double: " + largeDecimalNumber);

        // Short
        short smallNum = 1000;
        System.out.println("Short: " + smallNum);

        // Long
        long bigNumber = 123456789L;
        System.out.println("Long: " + bigNumber);
    }
