Java is known for its Just-In-Time (JIT) compilation, which means that the code is compiled at runtime for optimal performance. On the other hand, .NET Core uses Ahead-Of-Time (AOT) compilation, where the code is compiled before execution. This fundamental difference in compilation technique...
So to summarise everything:The Java Virtual machine (JVM) is the virtual machine that runs on actual machine (your computer) and executes Java byte code. The JVM doesn’t understand Java source code, that’s why we need to have javac compiler that compiles *.java files to obtain *.clas...
