The following was a question I needed to understand for my course. How to enter the command line argument in eclipse to receive the requested output.

 

import java.util.*;

import java.io.*;

 

public class LineNum {

 

 

public static void main(String[] args) throws Exception{

 

int n = Integer.parseInt(args[0]);

Queue myQueue = new LinkedList<>();

String data="";

 

BufferedReader keyBorad = new BufferedReader(new InputStreamReader(System.in));

 

String line;

while((line = keyBorad.readLine()) != null) {

myQueue.add(line); //adding element to the queue

}

 

if(n > myQueue.size()){

System.out.println("Queue contains less than "+n+" items.");

return;

}

for(int i=0 ; i< n ;i++){

data = myQueue.remove(); //removing element from the queue

}

System.out.println(n+ " from the first is "+data);

}//end of main() method

}//end of class LineNum

 

 

 

• Sample runs would be as follows.

 

• >java LineNum 2
• apple
• save
• that
• is
• too
• me
• 2 from the first is save

 

• >java LineNum 3
• this
• is
• not
• a
• shorter
• version
• 3 from the first is not
