在Java Swing中显示警报对话框

Question

我想在出现异常时发出警报,例如在代码中:

try
{
    //the code here
}
catch(Exception e)
{
    //show an alert dialog here
}

我需要一个示例或代码片段.

Answer 1

你可以用JOptionPane.showMessageDialog与WARNING_MESSAGE:

JOptionPane.showMessageDialog(yourFrame,
    "WARNING.",
    "Warning",
    JOptionPane.WARNING_MESSAGE);

Answer 2

试试这个:

JOptionPane.showMessageDialog(null, "My Goodness, this is so concise");

如果您静态导入JOptionPane.showMessageDialog,则进一步减少为

showMessageDialog(null, "This language just gets better and better!");
