14 Sep Java Tutorial | Learn Java Programming
Java is a widely used programming language launched in 1994. It easily runs on multiple platforms such as Windows, Linux, and macOS. Java comes with a compiler and interpreter. Java came as an enhancement to C++ and removed complicated features. The current version of Java is Java 20.
A slogan was created by Sun Microsystems for Java, which describes its cross-platform advantage,
Write once, run anywhere
Java is quite popular with more than 10 million Java developers worldwide. It is the No. 1 platform for the cloud.
- 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.
