Skipping the BufferedReader readLine() method in java
- by DDP
Is there a easy way to skip the readLine() method in java if it takes longer than, say, 2 seconds?
Here's the context in which I'm asking 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 a class I wrote, and the receive method, which contains a BufferedReader called "in", is this:
public String recieve()
{
try { if(active) return in.readLine(); }
catch(Exception e) { System.out.println("Comm Error 2: "+e); }
return "";
}
I've noticed that the program stops and waits for the input stream to have something to read before continuing. Which is bad, because I need the program to keep looping (as it loops, it goes to all the other clients and asks for input). Is there a way to skip the readLine() process if there's nothing to read?
I'm also pretty sure that I'm not explaining this well, so please ask me questions if I'm being confusing.
