Analysis and solution of java.lang.ArrayIndexOutOfBoundsException anomaly

Reference: http://blog.csdn.net/javaeeteacher/article/details/4485834

This is a very common exception, from the name of the array subscript out-of-bounds error, the workaround is to see why the subscript is out of bounds.

The following is an example of an error:

Exception in thread "main" Java.lang.arrayindexoutofboundsexception:2
At Test4. State.nextstates (state.java:93)
At Test4. State.main (state.java:478)

The following information can be obtained from these hints:

1, error occurred in 93 lines

2. When an error occurs, the underlying value is 2

The next step is to analyze why the subscript value is 2 and can be solved.
