Java substring exactly 3 letters from each word in the same string

问题

我有这个练习,我必须使用子字符串,并且从每个月中只显示前3个字母,如Jan,Feb等。我知道我必须使用months.substring(0,3)之类的东西,但我不知道如何用它来编写程序,你能指点我如何做吗?

  1. String months[] = {"January ", "February ", "March ", "April ", "Mai ",
  2. "June ", "July ", "August ", "September ", "October ", "November ", "December "};
  3. for (String month : months) {
  4. String abbreviatedMonth = month.substring(0, 3);
  5. System.out.print(abbreviatedMonth);
  6. }
英文:

I've got this exercise in which I have to use the substring and from each month to only display me the first 3 letters, Jan,Feb, etc. I know I have to use months.substring(0,3) or something like that but I don't know to do a program with that, can you point me on how to do it?

那就是你要寻找的内容

  1. for(String month : months){
  2. System.out.print(month.substring(0, 3) + " ");
  3. }
英文:

That's what you are looking for

  1. for(String month : months){
  2. System.out.print(month.substring(0, 3) + " ");
  3. }
