Java-在类中找不到 Main 方法

Question

我知道这个主题已经被破坏了几次，但是当我按照据说在其他主题中修复的方式修复它时遇到了错误。

public static class FlowAp extends JFrame{
    String one = "One";
    String two = "Two";
    String three = "Three";
    String four = "Four";
    String five = "Five";

public static void main(String argv[]){
    FlowAp fa=new FlowAp();
    //Change from BorderLayout default
    fa.getContentPane().setLayout(new FlowLayout());
    fa.setSize(200,200);
    fa.setVisible(true);
}
FlowAp(){

    JButton one = new JButton("One");
    getContentPane().add(one);
    JButton two = new JButton("Two");
    getContentPane().add(two);
    JButton three = new JButton("Three");
    getContentPane().add(three);
    JButton four = new JButton("four");
    getContentPane().add(four);
    JButton five = new JButton("five");
    getContentPane().add(five);

}
}

当我实际上在它们看起来应该出现的地方放入括号时，flowap 出现了另一个错误。“无效的方法声明”

尝试删除“静态”:

public class FlowAp extends JFrame{
