Advantages of Java - Saidemy

​

Multi-threading

Java allows you to perform multiple tasks simultaneously since it is multi-threaded. The advantage is that you can use the same memory and other resources for executing numerous threads at once.

​

Secure

Through its security features, Java allows us to create virus-free and temper-free systems as well as run in a runtime environment that does not interact with the operating system.

​

Platform independent

While C and C++ are compiled on a platform-specific machine, Java is designed to be written once and executed anywhere. Java is compiled into bytecode, which is platform-independent, and you can run it on any machine. It also ensures security. Java programs can be run on a machine if the Java Runtime Environment (JRE) is installed.

​

Portability

Java code is quite portable. You can write it in a Windows environment and run it in a Linux environment.

​

Object-Oriented

An object based on the object model has data and behavior. It can be easily extended due to its object-based nature.

​

Robust

However, the main improvement in Java is in the handling of mishandled exceptions and memory management through the inclusion of exception handling and garbage collection.

Let’s now write the first Java program, which is the Hello world program

Hello World Program

​

Here is our first Java program. We have declared a class called HelloWorld and printed the following message:

“Hello World” message inside it. The code is as below:

​

public class HelloWorld {

public static void main(String[] args){

System.out.println(“Hello World”);

}

}
