java - 将日期格式从 mm/dd/yyyy 转换为 MM DD, YYYY

Question

例如，它将日期 2/15/2014 格式化为 2014 年 2 月 15 日

我尝试过切换来获取月份并且成功，但我不知道如何获取之后的其余部分。

这是我到目前为止所拥有的:

private void formatDate()
{
    String month = dateDeparture.substring(0, dateDeparture.indexOf('/'));
    switch(dateDeparture)
    {
    case 1:
        month = "January";
        break;
    case 2:
        month = "February";
        break;
    case 3:
        month = "March";
        break;
    case 4:
        month = "April";
        break;
    case 5:
        month = "May";
        break;
    case 6:
        month = "June";
        break;
    case 7:
        month = "July";
        break;
    case 8:
        month = "August";
        break;
    case 9:
        month = "September";
        break;
    case 10:
        month = "October";
        break;
    case 11:
        month = "November";
        break;
    default:
        month = "December";
        break;  
    }
    dateDeparture = month+" "+dateDeparture.substring(dateDeparture.indexOf('/'),  dateDeparture.lastIndexOf('/'))+ dateDeparture.substring(dateDeparture.lastIndexOf('/'));

}

Java 有一个名为 SimpleDateFormat 的类。用它来实现你正在做的事情。
