我的编译讨厌第62行 - public void run（）{ - 我需要帮助修复它。我复制并粘贴了已经工作的程序的行，所以我不知道它是如何工作的。 修改的 抱歉，伙计们，这是我的错误：
TTT.java:62: error: illegal start of expression
public void run() {
^
TTT.java:62: error: illegal start of expression
public void run() {

TTT.java:62: error: ';' expected

答案 0 :(得分：3)
您似乎已在另一个方法声明中定义了一个方法，即run()中的actionPerformed(ActionEvent e)。
Java中不允许这样做。
您似乎对static void run()的声明有误解，这不是构造函数;它是一个返回类型为void的方法声明。
答案 1 :(得分：1)
changeBkColor是一个无限循环，因此在调用构造函数之后，永远不会调用frame.setVisible（true）。可能是一个问题。
