如何随机设置按钮的文本？

Question

是否可以随机设置按钮/按钮文本，例如

案例1；

我有 1 个按钮和 3 个文本，我想在按下按钮时将按钮的文本随机设置为三个文本之一。

String text1 = "Lucky", text2 = "Not lucky", text3 = "BadLuck, press the button again";
JButton button = new Jbutton(""); // I want this button to have one of the text from above randomly.

案例2；

我有 3 个按钮和 1 个文本，我想将文本随机分配给三个按钮之一

String text = "I was chosen";
JButton button = new Jbutton("Press me"); // when this button is pressed, I want at randomly for one of the buttons below to get the text "I was chosen".
JButton button1 = newJbutton("");
JButton button2 = newJbutton("");
JButton button3 = newJbutton("");

提前致谢！

编辑：

String text = "text";
JButton[] arr = {button1, button2, button3};
Random r = new Random();
arr[r.nextInt(arr.length)].setText(text);

Answer 1

案例一

String []texts = {"X","Y","Z"};
Random r = new Random();
JButton button = new JButton(texts[r.nextInt(texts.length)];

案例 2

text = "I was chosen";
JButton button1 = new Jbutton("");
JButton button2 = new Jbutton("");
JButton button3 = new Jbutton("");
List<JButton> buttons = Arrays.asList(button1, button2, button3);
Random r = new Random();
buttons.get(r.nextInt(buttons.size())).setText(text);

编辑答案

String text = "text";
JButton[] arr = {button1, button2, button3};
Random r = new Random();
JButton b = arr[r.nextInt(arr.length)];
b.setText(text);
b.setEnabled(false);

Answer 2

你可以在这两种情况下使用数组来实现你想要的，使用随机数来选择文本。

每个例子的案例一：

String[] arr = {"Lucky", "Not lucky", "BadLuck, press the button again"};
Random r = new Random();
JButton button = new JButton(arr[r.nextInt(arr.length)]; 

这与具有JButton 数组的情况二相同。

Answer 3

List<JButton> buttons = Arrays.asList(button1, button2, button3);
List<String> texts = Arrays.asList(text1, text2, text3);

Random rand = new Random();
buttons.get(rand.nextInt()).setText(texts.get(rand.nextInt()));
