Java MCQ's Questions Set 1. Portability. Print Excel Barcode. The difficulties are mostly version-skew problems between JDK 1.1 and the older AWT GUI toolkit (on the one hand) and JDK 1.2 with the newer Swing GUI toolkit. Java is platform independent. A computer software application is considered portable to a new environment if the effort required to adapt it to the new environment is within reasonable limits. Recently, the Java programming language and runtime environment has made it possible to have programs that run on any operating system that supports the Java standard (from Sun Microsystems) without any porting work. Java provides three distinct types of portability: Source code portability: A certain Java program must produce identical results, CPU , of the operating system or the underlying Java compiler. ANSI C++ might mean portable source code, as long as you stay away from platform-specific extensions. This is called portability. But you’ll see portability talked about in the early days of C, and later with Java.” Nonetheless, Peterson said, if you look at the enterprises that standardized on Java, they also standardized on specific server platforms and specific operating systems and other specific technology.
