I have 4 methods which invokes my browser, logs in to the page and does some actions. When I run the code as a Java application, the browser opens up and the actions are performed, but when I run as a TestNG test, the console shows all 4 test passed, but it also shows Null Pointer Exception. Also, when running as testng test, it's not invoking my browser and performing the actions.

Instead of running the script in the main method, you should run the script as a "TestNG Test" and to do the initial setup before running the tests you can use, BeforeSuite and AfterSuite.
So, you need to make two changes in your script:
Insert a tag @BeforeSuite before the method launchApplication() and insert a tag @AfterSuite before the method closeApplication() which would perform the setup and the closing of the driver before and after executing the script.
Remove the whole main method that you have written and then run the script as "TestNG Test", your tests should run as expected.
