Are standalone applications becoming obsolete?

I was wondering if standalone applications were becoming/are obsolete to web applications. The reason I wanted to know this was that I know a decent bit on how to develop standalone projects (primarily in Java) but am having a hard time learning Web Application Development. I just wanted to know if there is still use in me working on my standalone applications or if I should just push through the learning curve of web development. I could do either option, but I would rather stay with developing standalone applications. However, I don't want to focus on a dying field and get left completely behind.
