自定义JOptionPane消息对话框按钮时出错

Question

I'm receiving the error: no suitable method found for showMessageDialog when trying to customise a showMessageDialog button to say "Start" instead of OK.

This is the code:

JOptionPane.showMessageDialog(frame, radioPanel, "Start Game", JOptionPane.PLAIN_MESSAGE, null, new String[]{"Start"});

Could someone point out why I might be receiving this error.

Thanks in advance

Answer 1

There are 3 overloads of showMessageDialog :

• One with 2 arguments
• One with 4 arguments
• One with 5 arguments

You are trying to call this method with 6 arguments, so none apply. You need to carefully read the documentation to decide which one you require.
