I have to build a class using Thread.
This class will have a method called log(String str). This
String will be passed into this method from application to store
it into a file. I have to use thread so that application does
not have to wait until I am done writing lgging record to a file.
Since I am new in Thread, if anybody help me to implement this,
it will be great.
There are two ways to create threads. You can extend the Thread class (java.lang.Thread), or you can make a new class that implements Runnable (java.lang.Runnable) and create a generic Thread using an object of your Runnable class.
class YourThread extends Thread {
...
}
class YourThread implements Runnable {
...
}
In either case, you need to have a method called run which does whatever it is the thread is supposed to do...
public void run() { ... }
In your case, your run method is going to wait for someone to call log(String str) and then do something with that String. I suggest you look at the following in the Java language and API documentation:
synchronized keyword
Object.wait()
Object.notify()
java.io.FileOutputStream
That should give you some ideas on how to proceed. If you need more help just ask.
