To learn Java, you can start by reading online tutorials and guides such as the Oracle Java Tutorials (https://docs.oracle.com/en/java/), or the Java Tutorials on the Java website (https://docs.oracle.com/en/java/). These resources provide an introduction to the basics of Java, including language syntax, data types, and control structures.



You can also practice writing Java code by working through exercises and examples. Platforms like Codecademy, Coursera, Udemy, edX, and Khan Academy offer interactive Java courses that include quizzes, exercises, and projects to help you practice and apply what you've learned.

It's also a good idea to download the Java Development Kit (JDK) from Oracle's website (https://www.oracle.com/java/technologies/javase-downloads.html) and use it to set up a development environment on your computer. This will allow you to write, run, and test your own Java programs.

Additionally, you can also check out Java community sites such as Stack Overflow (https://stackoverflow.com/questions/tagged/java) and Oracle's Java Developer Community (https://community.oracle.com/community/developer) for answers to common Java-related questions and to connect with other Java developers.
