Teaching experience also no problem , you can do a job in it field.
But Java is a evergreen forever. Totally 3000 billion devices r depends on Java. I'm suggesting you that if you choose Java your life will be good in especially in your career.
As a Java developer you need to know framework s, core Java, advance Java, database(Oracle,MySQL), front end side (HTML, CSS, JavaScript, jquey, angular J's) for every technology minimum required Java. Without Java there is nothing in our it field including programming language.
You need to know.
1. Concept
2. Syntax.
3. Business logic
4. Debugging.

Problem solving skills.
Most people tend to focus on a specific language, but the most valuable skill you can possibly develop in programming is your logical and analytical ability.
There are multiple ways to do it. Get back to your basics. Know your data structures and algorithms. Start participating in long challenges on CodeChef regularly.
The term "problem solving" may seem very wide, but let me share an incident one of my student shared last week. She happened to have an interview at PayTM, and the interviewer asked her a simple problem regarding the maximum number of overlapping intervals at any point of time in a day.
The solution was simple to initialize an array for every minute of the day with 0's and incrementing all elements by 1 for each interval range and returning maximum value in array after processing all queries. She was going in the correct direction but discarded the solution due to loop involved for every range. This loop was not even necessary because the queries were offline and she had solved this sub-problem in one of the assignments earlier.
If you see, it is not about 'knowing' the solution, but about applying/modifying what you know. Knowing any amount of Java will not help if you do not know how to solve a problem.
