There's a reason many universities start with Java- it has strict rules and lays out code in a straightforward (if excessively-boiler-plate-heavy) way. For a beginner, Java is an excellent way to learn the fundamentals of programming before taking off the training wheels and continuing in more flexible, less-syntactically-rigorous direction like Python or JavaScript.

Sticking to a language before moving on is a common goal. However, in reality you are going to transition as you find languages that better suit you or your organization's requirements. Start with Java, not because it is optimal for your end goals, but because it will teach you what you like and dislike about programming and because your instructor is more familiar with it. That will give you a valuable perspective and allow you to make a more informed decision later.

There are many ways to solve problems in different languages, but the "best" language pragmatically is the one that you feel most comfortable using. In that respect, programming is like woodworking- you want to let the tool do the work. If there is another language that is "better" objectively but more difficult or confusing to you, you will counteract the anticipated benefits by having to struggle to write code.
