Try this code. This will read in the input file (input.txt) and output whatever you set as FindMe to output.txt. Note: Make sure input.txt is in the same location as the code.

Example input file:

Code:

10/10/2008,server1,xxx.xxx.xxx.xxx
10/10/2008,server2,xxx.xxx.xxx.xxx
12/04/2008,server1,xxx.xxx.xxx.xxx
16/07/2008,server1,xxx.xxx.xxx.xxx

Code:

Code:

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.io.Writer;

public class StringFind {
	
	public static String Inputpath;
	public static String FindMe;
	public String strLine;
	
	public void openFile(){

		String newLine = System.getProperty("line.separator");
		
		try {
			Writer output = new BufferedWriter(new FileWriter("output.txt"));
			
			FileInputStream in = new FileInputStream(Inputpath);
			BufferedReader br = new BufferedReader(new InputStreamReader(in));
		
		while ((strLine = br.readLine()) != null){
			
			if (strLine.contains(FindMe))	{
				output.write(strLine);
				output.write(newLine);
			}

			}
				output.close();
				System.out.println("Completed. Output file generated.");
				
		}catch(Exception e)	{
			System.out.println("OUCH! I fell over.");
			System.exit(0);
		}
	}

	public static void main(String[] args) {
		
		StringFind sf = new StringFind();
		
         Inputpath = "input.txt";
		 FindMe = "10/10/2008";
		
		sf.openFile();
				
	}
}

This code is looking for: 10/10/2008

So the output will be:

Code:

10/10/2008,server1,xxx.xxx.xxx.xxx
10/10/2008,server2,xxx.xxx.xxx.xxx
