1. Platform Independence: One of Java's most significant advantages is its "write once, run anywhere" (WORA) capability. Java code is compiled into an intermediate form called bytecode, which can run on any platform with a Java Virtual Machine (JVM). This makes Java applications portable and compatible across different operating systems.
2. Object-Oriented: Java is an object-oriented programming (OOP) language, which means it organizes code into classes and objects. OOP principles such as encapsulation, inheritance, and polymorphism provide developers with a powerful way to model and organize complex systems.
3. Garbage Collection: Java features automatic memory management through garbage collection. The JVM automatically frees up memory occupied by objects that are no longer in use, making memory management less error-prone for developers.
4. Rich Standard Library: Java comes with a vast standard library (Java API), providing a wide range of pre-built classes and methods for common tasks. This extensive library simplifies and accelerates application development.
