Basic Java program for implementation operators, variables, control flow statements

 public class BasicJavaProgram {

    public static void main(String[] args) {

        // Variables

        int num1 = 10;

        int num2 = 5;

        boolean isLess = num1 < num2;

        // Logical Operators

        boolean logicalAnd = (num1 > 0) && (num2 < 10);

        boolean logicalOr = (num1 > 0) || (num2 < 10);

        boolean logicalNot = !(num1 == num2);

        // Conditional Statements

        }

        // Looping Statements

        System.out.println("Printing numbers from 1 to 5:");

        for (int i = 1; i <= 5; i++) {

            System.out.print(i + " ");

        }

        System.out.println(); // Move to the next line

        // Switch Statement

        int dayOfWeek = 3;

        String dayName;

        switch (dayOfWeek) {

            case 1:

                dayName = "Sunday";

____________________

This program showcases the usage of variables (num1, num2), arithmetic operators (+, -, *, /, %), comparison operators (==, !=, >, <, >=, <=), logical operators (&&, ||, !), conditional statements (if, else if, else), looping statements (for loop), and the switch statement. It demonstrates basic operations and control flow in Java.
