Get system's date ddmmyyyy
提问by Xander
It's probably an easy question but how do you get the system date in format as ddmmyyyyin eclipse. So without any letters, spaces or other characters?
这可能是一个简单的问题，但是您如何ddmmyyyy以 eclipse中的格式获取系统日期。所以没有任何字母、空格或其他字符？

String todayAsString = new SimpleDateFormat("ddMMyyyy").format(new Date());
Eclipse is an IDE. Java is the language. Googling for "format a date in Java" and "current date in Java" would have led you to hundreds of pages telling you the answer. What matters is the language: Java. Not the IDE, which is just a tool to generate and compile Java code.
Eclipse 是一个 IDE。Java是语言。谷歌搜索“在 Java 中格式化日期”和“在 Java 中的当前日期”会引导您找到数百页告诉您答案。重要的是语言：Java。不是 IDE，它只是一个生成和编译 Java 代码的工具。

您可以使用此代码，并且可以将格式更改为您喜欢的任何格式。
import java.text.SimpleDateFormat;
import java.util.Date;
public class MainClass {
public static void main(String[] args) {
String pattern = "MMddyyyy";
SimpleDateFormat format = new SimpleDateFormat(pattern);
// formatting
System.out.println(format.format(new Date()));
}
}

试试这个：
Calendar cal= Calendar.getInstance();
String cal_for_month = cal.get(Calendar.MONTH);
String cal_for_year = cal.get(Calendar.YEAR);
String cal_for_day = cal.get(Calendar.DAY_OF_MONTH);
