/**


* Test jtable add data, delete data frequently operation, jtable the array of cross-border processing


* In the work if encountered frequent operation JTable data, especially the speed of the situation, often encounter


* Exception in thread "awt-eventqueue-0" Java.lang.ArrayIndexOutOfBoundsException


* Such an array of exceptions, the introduction of swing here a thread, can be a good solution to this problem


* For the same people who encounter such problems for reference.
