Java has been one of the most popular programming language for many years.
Java is Object Oriented. However it is not considered as pure object oriented as it provides support for primitive data types (like int, char, etc)
The Java codes are first compiled into byte code (machine independent code). Then the byte code runs on Java Virtual Machine (JVM) regardless of the underlying architecture.
Scope of a variable is the part of the program where the variable is accessible. Like C/C++, in Java, all identifiers are lexically (or statically) scoped, i.e.scope of a variable can determined at compile time and independent of function call stack. Java programs are organized in the form of classes. Every class is part of some package. Java scope rules can be covered under following categories
Software developers are the creative minds behind computer programmes. Some develop applications that allow people to do specific tasks on a computer or another device. Others develop the underlying systems that run the devices or that control networks. Once software developers have delivered the final software system, they will also help in maintaining and updating the program to ensure that all security problems are fixed, and it operates with new databases.
