You can follow the following steps:-

1. Create your credential files

2. Set up Amazon EC2 Client

3. Use the ID of the instance you want to stop

4. Stop the EC2 Instance.

Here is the code for doing that :-

package com.ec2application.ec2application;

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.ec2.AmazonEC2;
import com.amazonaws.services.ec2.AmazonEC2ClientBuilder;
import com.amazonaws.services.ec2.model.StopInstancesRequest;

public class EC2Stop
{
    private static final AWSCredentials AWS_CREDENTIALS;
    
    static {
        // Your accesskey and secretkey
        AWS_CREDENTIALS = new BasicAWSCredentials(
                "id",
                "secretkey"
        );
    }
    public static void main(String[] args) {
        
        // Set up the amazon ec2 client
        AmazonEC2 ec2Client = AmazonEC2ClientBuilder.standard()
                .withCredentials(new AWSStaticCredentialsProvider(AWS_CREDENTIALS))
                .withRegion(Regions.US_EAST_1)
                .build();
        
        //Stop EC2 Instance
        String instanecID = "i-0739c0ea4202ef40f";
        StopInstancesRequest stopInstancesRequest = new StopInstancesRequest()
                .withInstanceIds(instanecID);
         
        ec2Client.stopInstances(stopInstancesRequest)
                .getStoppingInstances()
                .get(0)
                .getPreviousState()
                .getName();
        System.out.println("Stopped the Instnace with ID: "+instanecID);
    }

}

Hope this helps.
