Introduction to the method of judging whether a string is time in java

Java method to determine whether a string is time: (Recommended: java video tutorial)

Introduce the jar package:

import org.apache.commons.lang3.time.DateUtils;

java determines whether it is a time code:

    private static String[] parsePatterns = {"yyyy-MM-dd","yyyy年MM月dd日",
            "yyyy-MM-dd HH:mm:ss", "yyyy-MM-dd HH:mm", "yyyy/MM/dd",
            "yyyy/MM/dd HH:mm:ss", "yyyy/MM/dd HH:mm", "yyyyMMdd"};
 
    public static Date parseDate(String string) {
        if (string == null) {
            return null;
        }
        try {
            return DateUtils.parseDate(str, parsePatterns);
        } catch (ParseException e) {
            return null;
        }
    }

You can determine by calling the parseDate method. If you need to determine other formats, just add them to parsePatterns.
