java - 如何只获取JSpinner的小时和分钟？

Question

我有一个 JSpinner。当我使用spinner.getValue()时，它给我Sun Mar 24 01:11:41 PDT 2013但我只想24小时格式的小时和分钟

Date date = new Date();
        SpinnerDateModel sm = new SpinnerDateModel(date, null, null, Calendar.MINUTE);

        JSpinner spinner = new JSpinner(sm);
        JSpinner.DateEditor de = new JSpinner.DateEditor(spinner, "hh:mm a");
        spinner.setEditor(de);
        if ( spinner.getEditor() instanceof JSpinner.DefaultEditor ) 
        {
                  JSpinner.DefaultEditor editor = ( JSpinner.DefaultEditor ) spinner.getEditor();
                  editor.getTextField().setEnabled( true );
                  editor.getTextField().setEditable( false );
        }

        System.out.println("Spinner:      "+spinner.getValue());

Answer 1

从 @mKorbel 的答案中提取要点:

System.out 使用其 toString 方法打印值对象，如果要打印格式化的值，则需要使用 Formatter，例如编辑器在代码中使用的:

Date date = new Date();
SpinnerDateModel sm = new SpinnerDateModel(date, null, null, Calendar.MINUTE);

JSpinner spinner = new JSpinner(sm);
JSpinner.DateEditor de = new JSpinner.DateEditor(spinner, "hh:mm a");
de.getTextField().setEditable( false );
spinner.setEditor(de);

System.out.println("Spinner:      "+de.getFormat().format(spinner.getValue()));
