Write a multi-threaded Java program to print all numbers below 100,000 that are both prime and fibonacci number (some examples are 2, 3, 5, 13, etc.). Design a thread that generates prime numbers below 100,000 and writes them into a pipe. Design another thread that generates fibonacci numbers and writes them to another pipe. The main thread should read both the pipes to identify numbers common to both.

Correction in the above codesanjay March 16, 2012 at 10:20 PM

hi , u are wrong with the sleep method. sleep(arg) is a static method of Thread class. u should not call it via thread class object
