我知道我做错了，我只是不知道该怎么办。
我需要所有美元值都必须采用美国货币格式。
据我所知，将System.out.format与货币格式化程序一起使用会出现问题。
我在Java方面没有太多经验，可能有更好的方法来做到这一点。
输出应如下所示。
import java.util.*;
import java.lang.*;
import java.text.*;

最佳答案
currency.format()的输出类型是String。
将％d更改为％s。
例如，
更改以下内容：“有了高中学历，您可以获得的收益比没有学位的人多％d。”
为此：“有了高中学历，您可以获得的百分比比没有学位的人多。”
