使用regex可以提取所需信息。

在https://regex101.com/r/ifuwvg/1上尝试regex

Java代码：

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

public class Example {
    public static void main(String[] args) {
        final String regex = "^([a-zA-Z0-9]+)\\s{1}[a-zA-Z0-9\\.\\s]+Ksh([0-9,.]+)\\sfrom\\s([a-zA-Z0-9\\.\\s]+)\\son\\s([0-9/]+)\\sat\\s([0-9:]+)\\s[A|P]M\\s.*$";
        final String string = "PF56S55yy Confirmed.You have received Ksh6,495.00 from Guaranty Trust Bank Limited 910201 on 5/6/21 at 10:07 PM New M-PESA balance is Ksh10,103.45. Separate personal and business funds through dummytext la dummytext on *377#.";

        final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
        final Matcher matcher = pattern.matcher(string);

        if(matcher.find()) {
            String code = matcher.group(1);
            String amountReceived = matcher.group(2);
            String from = matcher.group(3);
            String date = matcher.group(4);
            String time = matcher.group(5);

            String format = "code: %s amount received: %s from: %s date: %s time: %s";
            System.out.println(String.format(format, code, amountReceived, from, date, time));
        }
    }
}

code: PF56S55yy amount received: 6,495.00 from: Guaranty Trust Bank Limited 910201 date: 5/6/21 time: 10:07
