我正在尝试从一个被调用的方法中设置项目,FootballClub到目前为止它很好.但后来我从它创建了一个arrayList,我不知道怎么找不到将这些信息存储到JTable中的方法.问题是我找不到设置固定行数的方法

这是我的代码:

类StartLeague:

import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;

public class startLeague implements LeagueManager{

//setting the frame and other components to appear

public startLeague(){
    JButton createTeam = new JButton("Create Team");
    JButton deleteTeam = new JButton("Delete Team");

    JFrame frame = new JFrame("Premier League System");
    JPanel panel = new JPanel();
    frame.setSize(1280, 800);
    frame.setVisible(true);
    frame.add(panel);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    String col[] = {"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};

    panel.setLayout(new GridLayout(20, 20));
    panel.add(createTeam);
    panel.add(deleteTeam);
    panel.add(new JLabel(""));
    //JLabels to fill the space
    }
    } …

我有这个问题从一个意图访问额外的.我正在解析的值是一个long类型,我需要将此值存储在数据库中.

所以这就是我到目前为止所做的:

主要活动:

        setContentView(R.layout.activity_main);

        View createButton = findViewById(R.id.btn_create);
        View editButton …
