动态创建JButtons [英] Creating JButtons dynamically

问题描述

你好我有这个设置

private JButton btnFoo, btnBar;

我需要获得以下每个按钮

And I need to get for each button the following

        btnFoo = new JButton("Foo");
    btnFoo.addActionListener(this);
    add(btnFoo);

在Java中是否可以为我声明的每个按钮动态创建它？
，因为当我有5个按钮时，我不想要3x5 = 15行代码，只需要几行动态创建按钮。

Is it possible in Java to create this dynamically for each button I declare? because when I have like 5 buttons I don't want 3x5 = 15 lines of code but only a few lines with dynamically created buttons.

推荐答案

写一个小循环并将你的按钮存储在一个数组中：

Write a little loop and store your buttons in an array:

private JButton buttons[] = new JButton[5];

String names[] = {"Foo", "Bar", "Baz", "Fob", "Bao"};
for (int i = 0; i < buttons.length; ++i)
{
    JButton btn = new JButton(names[i]);
    btn.addActionListener(this);
    add(btn);
    buttons[i] = btn;
}
