Java中SimpleDateFormat类parse解析yyyy-MM-dd与yyyy-M-d是否可以混用

Java中SimpleDateFormat类parse解析yyyy-MM-dd与yyyy-M-d是否可以混用

直接上代码

public class TestDemo {
	public static void main(String[] args) throws InstantiationException, IllegalAccessException {
		String str1 = "2016-08-23";
		String str2 = "2016-8-23";
		SimpleDateFormat sdf1M = new SimpleDateFormat("yyyy-M-d");
		parseDate(sdf1M, str1);
		
		parseDate(sdf1M, str2);
		
		SimpleDateFormat sdf2M = new SimpleDateFormat("yyyy-MM-dd");
		parseDate(sdf2M, str1);
		
		parseDate(sdf2M, str2);
	}
	
	private static void parseDate(SimpleDateFormat sdf, String str) {
		try {
			sdf.parse(str);
			System.out.println(sdf.toPattern() + " to parse " + str + " Success!");
		} catch (ParseException e) {
			e.printStackTrace();
			System.out.println(sdf.toPattern() + " to parse " + str + " error!");
		}
	}
}
