Description

Java was developed in the 1990s by Sun Microsystems and is one of the most widely used programming languages worldwide. It enables the development of platform-independent applications through the use of the Java Virtual Machine (JVM). Java is commonly used in enterprise applications, web applications, and mobile applications.

✔Benefits

Platform independence.
Large community and support.
Rich collection of libraries and frameworks.

✖Limitations

Higher memory consumption compared to some other languages.
Slow startup times for applications.
Complexity in managing dependencies.

Trade-offs

Metrics
