Java Features

  • Architecture Neutral: Just compile your Java program and take it to another operating system. The same program works in another operating system as well without the need of recompiling it. This is why it is called Write Once, Run Anywhere, Anytime, Forever”.
  • Security: Java programs are secure since they get compiled first into byte code, which leads to their verification.
  • Auto Garbage Collection: Java comes with an automatic garbage collector, which makes the memory more efficient by reclaiming memory for reuse. In C++, garbage collection isn’t automatic, so we use the delete() function. But in Java, there is no need to use any function, since garbage collector work automatically being part of JVM.
  • Multi-threading: Java comes with the multi-threading concept, which makes the program quite effective, unlike single-threading. You can easily execute multiple threads simultaneously with Java.
  • Pure Object Oriented Language: Java deals with Object Oriented Programming Language, so it has all the concepts of object-oriented such as Classes, Objects, Abstraction, Polymorphism, etc.
