嗨，我是碧玉报告的初学者，我得到了一个错误，这个下面的变量出现错误，我得到了这个错误

我从这个特定的表达中得到了这个。请帮助我，我真的没有得到错误的含义。对于这个错误，我将不胜感激，谢谢。我一直在花时间解决这个问题，但还是没有运气。
Cause:
Error evaluating expression for source text: ($V{Variable_4_1}.split(",")[$V{a}] != "" && $V{Variable_4_1}.split(",")[$V{a}] != null ? ($V{Variable_4_1}.split(",")[$V{a}].split("/")[2] + "/" + $V{Variable_4_1}.split(",")[$V{a}].split("/")[1] + "/" + $V{Variable_4_1}.split(",")[$V{a}].split("/")[0]) : " - ") + " - " + ($V{Variable_4_1_2}.split(",")[$V{a}] != "" && $V{Variable_4_1_2}.split(",")[$V{a}] != null ?

答案 0 :(得分：0)
这是由ArrayIndexOutOfBoundsException引起的（请参阅堆栈跟踪的底部）。 在您计算变量的某个位置，您将访问一个不存在的值数组。
它应该在这里的某个地方发生。请检查此代码
[$V{a}] or [2] or even [0]
这似乎太复杂且冗长的代码，也许您应该考虑将其拆分为多个变量）：
($V{Variable_4_1}.split(",")[$V{a}] != "" && $V{Variable_4_1}.split(",")[$V{a}] != null ? ($V{Variable_4_1}.split(",")[$V{a}].split("/")[2] + "/" + $V{Variable_4_1}.split(",")[$V{a}].split("/")[1] + "/" + $V{Variable_4_1}.split(",")[$V{a}].split("/")[0]) : " - ") + " - " + ($V{Variable_4_1_2}.split(",")[$V{a}] != "" && $V{Variable_4_1_2}.split(",")[$V{a}] != null ? ($V{Variable_4_1_2}.split(",")[$V{a}].split("/")[2] + "/" + $V{Variable_4_1_2}.split(",")[$V{a}].split("/")[1] + "/" + $V{Variable_4_1_2}.split(",")[$V{a}].split("/")[0]) : " - ")
因为我不知道您要在变量中输入什么值，所以我只能猜测错误发生的位置，但是我建议使用笔和纸运行这段代码以查看会发生什么。
