After some time, names suggested and then withdrawn, legend has it that the name Java was found in a coffee break in front of a hot and steaming cup of coffee from which the Java logo also derives. Introduction to the Java language The goal of the Java language has always been to create applications that adapt to various electronic devices; bypassing all the typical limitations of languages such as C and C ++ but maintaining the characteristics.  This choice also proved successful; because many programmers later started using the Java language, aided by their familiarity with their C background.  Networking A full range of ready-to-...

The C language The C l...
