How do different versions of the Java environment differ, and how can these differences affect application development?

Different versions of Java (JDK) differ by adding new features, improving performance, fixing bugs, and updating standard libraries. For example, starting with Java 8, lambda expressions and Stream API appeared, which greatly simplified working with collections and functional programming. In Java 9, a modular system (Project Jigsaw) was introduced, affecting the structure and packaging of applications.

These changes impact development in the following ways:

• Allow writing more concise and expressive code.
• Require updates to tools and libraries for compatibility.
• May affect the performance and security of applications.
• New versions may change the behavior of old APIs, requiring testing.

It is important to choose the Java version based on project requirements and the support of the libraries used.
