Declarations with scope (i.e. private, protected, or public) must be outsideyour functions, including the main()one. Move these declarations to the class level to fix this syntax error.
具有作用域（即private、protected、 或public）的声明必须在您的函数之外，包括函数main()。将这些声明移动到类级别以修复此语法错误。

The privateis being used in the body of a method. It can not be used there. It can be used in the body of a class ... outside the method.
所述private被在方法的主体使用。它不能在那里使用。它可以用在类的主体中……在方法之外。

private, protected, or publicare access modifiers. They should be used with member variables or methods of a Class.
private, protected, orpublic是访问修饰符。它们应该与 a 的成员变量或方法一起使用Class。
Class MyClass{
// private can be used here
private JFrame window;
public static void main(String[] args){
//private can not be used here. It makes no sense
JFrame localWindow;
}
}
