Advantages
  • May call resources available from C
    • Window/Graphic Systems
    • Database
    • Networking and Other Third Party Libraries
    • Higher performance as compiled (always) and as C (advantage with todays compilers)
Disadvantages
  • Classes with native methods, or library linking calls, may not be downloaded across the network.
  • Libraries may not be downloaded across the network.
  • Programmer must write a native library for every platform used.
So usually user defined native method can not be used remotely in Applet.
  • Can pre-download as a plugin
