Use SimpleDateFormat to get a Date-object from your string representation, then use Calendar for arithmetics followed by SimpleDateformat to convert the Date-object back to a string representation. (And handle the Exceptions I didn't do)
使用 SimpleDateFormat 从字符串表示中获取日期对象，然后使用 Calendar 进行算术运算，然后使用 SimpleDateformat 将日期对象转换回字符串表示。（并处理我没有做的异常）
public static String getNextDate(String curDate) {
final SimpleDateFormat format = new SimpleDateFormat("yyyy/MM/dd");
final Date date = format.parse(curDate);
final Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.add(Calendar.DAY_OF_YEAR, 1);
return format.format(calendar.getTime());
}

use java Calendar and you can use to do some date arithmetic such as adding day, months and years
使用java Calendar，你可以用它来做一些日期运算，比如添加日、月和年
public static String getNextDate(String curDate) {
String nextDate = "";
try {
Calendar today = Calendar.getInstance();
DateFormat format = new SimpleDateFormat("yyyy/MM/dd");
Date date = format.parse(curDate);
today.setTime(date);
today.add(Calendar.DAY_OF_YEAR, 1);
nextDate = format.format(today.getTime());
} catch (Exception e) {
return nextDate;
}
return nextDate;
}

If you want a more native Java way you could split the string using String.split("/") and then add to the date part. However doing this requires that the carry is handled and that you track leap years.
如果您想要更原生的 Java 方式，您可以使用 String.split("/") 拆分字符串，然后添加到日期部分。但是，这样做需要处理进位并跟踪闰年。
