Skipping readLine () method of BufferedReader in java

Question

Is there an easy way to skip the readLine () method in java if it takes more than, say, 2 seconds?

Here is the context in which I ask this question:

public void run()
{
    boolean looping = true;
    while(looping) {
        for(int x = 0; x<clientList.size(); x++) {
            try {
                Comm s = clientList.get(x);
                String str = s.recieve();
                // code that does something based on the string in the line above
            }
            // other stuff like catch methods
        }
    }
}

Comm is the class I wrote, and the get method that contains the BufferedReader, called "in", is as follows:

public String recieve()
{
    try { if(active) return in.readLine(); }
    catch(Exception e) { System.out.println("Comm Error 2: "+e); }
    return "";
}

I noticed that the program stops and waits for the input stream to read something before continuing. This is bad because I need a program to continue the loop (since it is a loop, it accesses all other clients and asks for input). Is there a way to skip the readLine () process if there is nothing to read?

I am also sure that I am not explaining it very well, so please ask me questions if I get confused.
