"illegal start of expression" help needed

[drumbum360]

I'm trying to write a Java program that will open a .txt file and read the contents of it to do payroll. I'm new to Java and haven't been too successful at this program attempt tonight and I need some help with an error I'm getting. The error states:
employeePayroll.java:29: ';' expected
for (int i = 0; i+3)
^
employeePayroll.java:35: illegal start of expression
}
^
2 errors

And my code is:

//Imports the keyboard scanner
import java.util.Scanner;
//To use the classes that use a .txt file
import java.io.*;

public class employeePayroll
{
	public static void main(String[] args) throws IOException 
	{  
		String filename; //file name
		String name; 	  //employee name
		
		//Create a Scanner object to read input
		Scanner keyboard = new Scanner (System.in);

		
      // Open the file.
		FileReader freader = new FileReader("data.txt"); 
		BufferedReader inputFile = new BufferedReader(freader); 
		String str; 
		// Read the first item. 
		str = inputFile.readLine(); 
		// If an item was read, display it and read the remaining items.
		int i = 0;
		for (int i = 0; i+3)
		{
		  System.out.println(str); 
 		  str = inputFile.readLine(); 
		} 
		inputFile.close();
	}
}

//ALL DONE!

Can you please help me figure out what is wrong? I want the JAVA to read every third line of the .txt file because those lines contain the names for the payroll.

Thank you

As long as I know, for loops need to semicolons my friend, as they also need a condition to end the loop, you may use: (here the condition is i being smaller than max)

for (i=0;i<max;i+=3) {...

or in case you don't know where to end, you should use a while loop:

end_achieved=0;
i=0;

while(!end_echieved) {
...
if(we_should_finish_this_loop) end_achieved=1;
}
