How to store data in Java

There are multiple ways to save data in Java, here are some common ways: 1. File saving: using Java’s File class and related input/output streams to save data to a file. Using classes like FileWriter or BufferedWriter to write data to a file, and FileReader or BufferedReader to read data from a file. 2. Database saving: using Java’s JDBC API to connect and operate with relational databases like MySQL, Oracle, etc. Saving data to the database by executing SQL statements. 3. Serialization saving: using Java’s serialization mechanism to convert objects into byte streams, then save them to a file or database. Writing objects to a file or database using ObjectOutputStream, and reading objects from a file or database using ObjectInputStream. 4. Cache saving: utilizing Java’s caching frameworks like Ehcache, Redis, etc., to store data in memory, improving read and write performance. Depending on specific requirements and scenarios, choose the appropriate way to save data.
