覆盖变量？

Question

这是我的第一个java项目，所以我仍然在学习大量的东西以及如何应用它。

我正在为使用

的Titanfall 2制作一个随机加载的创建者

 double b = (int)(Math.random() * 6 + 1);

随机生成一个数字，对于我随机化的每组事物，我使用的变量。根据数字，将显示不同的文本，游戏中每个可能的选择一个数字。我的问题是，因为每个枪可以有两个mods代码中的枪模块是相同的但是如果偶然的两个mod的随机数相同它显示相同的mod，这是你在游戏中无法做到的。我想这样做，如果b == a然后它重新随机化b，但我无法弄清楚如何做到这一点。整个代码将在底部，并且图示显示我想要避免的情况，Gun mod 1和Gun mod 2的问题发生，bluej syas变量b已经定义，当我试图将它放在if中的第二个时（ b ==一个）

据我所知，你想继续随意，直到你得到一个与前一个不相等的值。
