[Back to Home](../README.md#java) # The Overview of Java Basic Syntax Here are some basic Java syntax rules: # List Of Content ## 1. Java code is case-sensitive. ## 2. The code is written in classes. ## 3. Each statement must end with a semicolon `;`. ## 4. Java comments start with `//` for single-line comments, or `/`and end with `/` for multi-line comments. ## 5. Java uses the curly brace `{}` to define the scope of methods and classes. ## 6. The main method is the entry point of a Java program and is defined as follows: ```java public static void main(String[] args) { // code goes here } ``` ## 7. To declare a variable, use the data type followed by the variable name, and optionally an initial value: ```java int num = 10; String message = "Hello, World!"; ``` ## 8. To output a message to the console, use the `System.out.println()` method: ```java System.out.println("Hello, World!"); ``` ## 9. To get input from the user, use the Scanner class: ```java import java.util.Scanner; Scanner scanner = new Scanner(System.in); String name = scanner.nextLine(); ```
