通过java 代码 提取下面字符串中的时间 S5P_NRTI_L2__HCHO___20220129T030719_20220129T100219_formaldehyde_tropospheric_vertical_column_hzs.json

可以使用正则表达式来提取字符串中的时间。以下是一个示例代码，可以提取出上述字符串中的起始时间和结束时间：

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class TimeExtractor {

    public static void main(String[] args) {
        String inputString = "S5P_NRTI_L2__HCHO___20220129T030719_20220129T100219_formaldehyde_tropospheric_vertical_column_hzs.json";
        Pattern pattern = Pattern.compile("(\\d{8}T\\d{6})_(\\d{8}T\\d{6})");
        Matcher matcher = pattern.matcher(inputString);
        if (matcher.find()) {
            String startTime = matcher.group(1);
            String endTime = matcher.group(2);
            System.out.println("Start time: " + startTime);
            System.out.println("End time: " + endTime);
        } else {
            System.out.println("No time found in input string.");
        }
    }

}

输出结果为：

Start time: 20220129T030719
End time: 20220129T100219
