我已经声明了这个JFRAME对象的一个实例，并将其命名为gui。 我肯定知道这个gui有效。 为什么我的gremlines不会在地图上移动？ 此外，当我尝试从anotehr方法调用doMoveDisplay（）时，它无法工作。但是它允许我在类的侧面调用doMoveDisplay（）和doMoveDisplay（此处为字符）。 我究竟做错了什么？ 如何修复我的gremlin run方法，以便gremlins每1000毫秒在地图上移动一次。 我的Gremlin博士有一个跑步方法。然而，它实际上并没有采取行动。当我让所有的gremlins按顺序执行它们时它工作得很好。 主线程也没有捕获gremlin构造函数抛出的异常
答案 0 :(得分：1)
虽然main方法已经移动了异常将被捕获的点，但是你抛出异常。
