Question

我很难让这个工作。我有一个非常大的.log文件，我需要读入代码，我需要解析和格式化代码，然后将其导出到包含正确顺序的正确信息的文本文档。到目前为止，这是我的代码：

import java.util.*;
import java.io.*;

public class chatLogParse {
public static void main(String args[]) throws IOException {

String path = "sampleData.log";
FileInputStream inputStream = null;
Scanner input = null;
String filename;
// Connecting to a file with a buffer
        PrintWriter outFile = new PrintWriter(
                              new BufferedWriter(
                              new FileWriter("ChatOutput.txt")));

try {inputStream = new FileInputStream(path);
input = new Scanner(inputStream, "UTF-8");
while (input.hasNextLine()) {
    String line = input.nextLine();
    System.out.println(line);
}
// note that Scanner suppresses exceptions
if (input.ioException() != null) {
    throw input.ioException();
}
} finally {
if (inputStream != null) {
    inputStream.close();
}
if (input != null) {
    input.close();
    }
   }
  }
 }

以下是日志文件的片段：

以下是我的输出格式：

8:25:00 AM [John Smith] to [Steve Jobs] but didn't give me the info I needed
8:25:00 AM [John Smith] to [Steve Jobs] i have no clue whats going on

我需要代码来排序代码行，只选择包含LANTALK的行，按时间顺序应用格式和输出，同时丢弃所有其他行。我不知道该怎么做。任何你能给我的帮助将不胜感激！谢谢！

使用Java解析日志文件以仅显示消息
