When I run the following code which I got from Head First Java (it uses Java 5.0, by the way), I get the following error:
run:
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: Accum.getAccum
at ThreadOne.<init>(TestThreads.java:27)
at TestThreads.main(TestThreads.java:18)
Java Result: 1
BUILD SUCCESSFUL (total time: 2 seconds)

Here is the code:



Can anybody help me with this problem? I have marked the problem lines, by the way.

Thanks! That helped a lot! But now I am getting the following error:

run:
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: Accum.getAccum
at ThreadOne.<init>(TestThreads.java:27)
at TestThreads.main(TestThreads.java:18)
Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)

What does "Erroneous sym type" mean?

No idea. After fixing those two catch errors the code compiles just fine on my system (Windows 7, JDK 1.6.0_25). The results are random though, but that makes sense since there is no synchronization on the updating of the counter.
