how to get Jmeter test result from JAVA Class by using JMeter API

Question

I'm new to JMeter. I found the following code to run a JMeter test plan(.jmx) from JAVA project by using JMeter API StandardJMeterEngine.

But how can I get the execution result as return?

I saw many articles about SampleResult. If this is a solution, can you please provide details about how can I integrate my sampleResult into the existing JMeter test plan.

    // JMeter Engine
    StandardJMeterEngine jmeter = new StandardJMeterEngine();

    // Initialize Properties, logging, locale, etc.
    JMeterUtils.loadJMeterProperties("../jmeter.properties");
    JMeterUtils.setJMeterHome("../apache-jmeter-2.11");
    JMeterUtils.initLogging();
    JMeterUtils.initLocale();

    SaveService.loadProperties();

    // Load existing .jmx Test Plan
    FileInputStream in = new FileInputStream("../Integ.jmx");
    HashTree testPlanTree = SaveService.loadTree(in);
    in.close();
    // Run JMeter Test
    jmeter.configure(testPlanTree);
    jmeter.run();

    <how to capture result here?????????????????>
    jmeter.exit();

If you want to access the test results directly in Java without the workaround via file output, you can redefine the result collector and get notified for each sample event:

public class MyResultCollector extends ResultCollector {

    public MyResultCollector(Summariser summer) {
        super(summer);
    }

    @Override
    public void sampleOccurred(SampleEvent e) {
        super.sampleOccurred(e);
        SampleResult r = e.getResult();
        if (r.isSuccessful()) {
            System.out.println("Response time in milliseconds: " + r.getTime());
        }
    }
}
