Visual Studio Code (VS Code) is a versatile code editor that provides a seamless environment for coding various programming languages, including Java. It offers exceptional support for Java with extensions like "Java Extension Pack". This extension pack makes Java development in VS Code efficient and user-friendly.
Java is a powerful programming language that provides an extensive range of classes and methods to create different programs. The most commonly used classes for input and output are java.io.Printstream and System.out. With these classes, you can easily create a simple output program that is displayed within the Java console window.
To take input from the user, methods from the java.util.Scanner class can be used. The Scanner class reads the input stream and stores it into tokens. The Scanner class has several methods to deal with tokens which include hasNext(), next(), hasNextType(), and nextType(). These methods can be used to check if there are more tokens in the input stream, return the next token string in the input stream, and return the next token in the input stream as a base type.
To create a working Java program, it is essential to have the latest Java Install Development Kit (JDK) installed. In VS Code, open or create a new folder, then create a new file with a '.java' file extension. A basic Java program consists of a class with a 'main' method. An example code would be:
public class HelloWorld{
public static void main(String[] args){
System.out.println("Hello World!");
}
}
After creating your program, save your file then proceed to compile and run it by clicking the run button on the top right of the VS Code editor. You will see the output "Hello World!" displayed in the terminal.
Congratulations! You have successfully created and run a Java program in Visual Studio Code. Keep practicing and building more complex Java applications using VS Code.
