Why Java programmers are in demand?

Despite having so many languages for creating applications and web development, Java programmers are always in demand. Read below to find out the reason behind this fact:

  • Java is guaranteed to be ‘write once and run everywhere’
  • Collection of objects invoking each other’s methods
  • A case sensitive language which makes it take different meanings for the same word typed differently.
