AWS or Amazon web services is a cloud service platform that provides on-demand computational services, databases, storage space, and many more services. EC2 or Elastic Compute Cloud is a scalable computing service launched on the AWS cloud platform. In simpler words, EC2 is nothing but a virtual computer on which we can perform all our tasks and we have the authority to configure, launch or even dissipate this virtual computer 

In this article, we will learn how to Java JDK11 on AWS EC2.

Prerequisite:

  1. AWS account.
  2. EC2 Instance.
  3. User with privileges to create Instance.

Implementation:

Follow the steps below to install Java JDK11 on AWS EC2:

Step 1: Create an AWS Elastic Cloud Compute Instance.

Step 2: Start the EC2 instance that you have created in Step 1.

Step 3: Connect to your EC2 Instance by clicking on Connect Button.

Step 4: A prompt will pop up after connecting.

Step 5: At first check, if Java JDK is already installed or not.

java --version

Step 6: If Java JDK is not installed on your virtual machine then install the Java JDK using the following command

sudo apt install openjdk-11-jdk-headless

Step 7: Wait for the process to end.

Step 8: We have successfully installed Java JDK11 on our EC2  instance, to check if JDK11 is installed or not, verify using the following command.

java --version

In this way, we can install Java JDK 11 on our EC2 instance using EC2 Instance Connect.

Let’s try to create a Java program and then execute that Java program on our EC2 instance:

Java




//java program to calculate sum of two numbers
import java.io.*;
class GFG {
    public static void main(String[] args)
    {
        int x = 10, y = 20;
        int sum = x + y;
        System.out.println("Sum is : " + sum);
    }
}


Use the following command to compile and execute our java program on AWS EC2 Instance –

To Compile - javac example1.java
To Execute - java GFG

Output

Note: if you also use a free tier account, make sure you delete all the resources you have used before logging out.
