本篇文章为大家展示了java获取当前日期是星期几的方法，代码简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。
第一种方法：/**
* 获取当前日期是星期几
*
* @param date
* @return 当前日期是星期几
*/
public String getWeekOfDate(Date date) {
String[] weekDays = { "星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六" };
Calendar cal = Calendar.getInstance();
cal.setTime(date);
int w = cal.get(Calendar.DAY_OF_WEEK) - 1;
if (w < 0)
w = 0;
return weekDays[w];
}
第二种方法：使用SimpleDateFormat格式化日期Date date = new Date();
SimpleDateFormat dateFm = new SimpleDateFormat("EEEE");
String currSun = dateFm.format(date);
System.out.println(currSun);
注：格式化字符串存在区分大小写
对于创建SimpleDateFormat传入的参数：EEEE代表星期，如“星期四”；MMMM代表中文月份，如“七月”；MM代表月份，如“07”；yyyy代表年份，如“2017”；dd代表天，如“05”
