Variables

Java | Variables: Variables are using to store the data.

---

Details of Variables:

    Variable Declaration and Initialization: Create the variable and assign the value to it.

                            Ex: int i = 1.

    Modification of Variables: Variables can modify by doing operators on them.

                             Ex: i = i + 2.

    Types of Variables: Variable types are integer, string, float/double and boolean.

                              Ex: 1 is integer, "Java" text with double quotes is string, 1.43 number with decimal values are float/double and true/false is boolean.

Here is the Code:

1. import java.io.*;
2. 
   
3. class Main {
4. public static void main (String[] args) {
5.     // Declaration and Assigning
6.     int i = 1;
7.     System.out.println(i);
8.     // Modification
9.     i = i + 2;
10.     System.out.println(i);
11.     // Types
12.     double j = 1.43;
13.     System.out.println(j);
14.     String s = "Java";
15.     System.out.println(s);
16.     boolean b = true;
17.     System.out.println(b);
18. }
19. }

Output:
