There is no one answer to this question as it depends on your individual circumstances. However, there are some things to consider that may help you make a decision.
For example, if you are planning on studying computer science in college, then it may be beneficial to learn Java before you start your studies. This way, you will already have a solid understanding of the basics and you can hit the ground running when you start your coursework.
On the other hand, if you are not planning on studying computer science in college, then you may not need to learn Java at all. There are many other programming languages that you can learn that will be just as useful, if not more so.
Ultimately, the decision of whether or not to learn Java before college is up to you. Consider your individual circumstances and make a decision based on what you think will be best for you.
