Python and Java are both languages that are widely used for AI. The choice between the programming languages depends on how you plan to implement AI. For example, in the case of data analysis, you would probably go with Python. However, given how popular AI is for mobile apps, Java, which is frequently used in this case, may well be the best language for this type of program. Python has hundreds of libraries that make any type of project possible, whether it is a mobile app, web app, data science, or artificial intelligence.
