Thread problem

[sharma ishu]

class A implements Runnable{
public void run(){
try{
sleep(5000); //Compiler Error: Cannot find method
}catch(Exception e){}
System.out.println("RUN");
}
}
Please explain why this shows such an error?

Can you please post complete code for the class?

Since 'sleep' is a static method of Thread class, to use it without class reference, you must access it from a class which IS-A Thread.

Hi ishu ,

You must be implement Runnable in this case,
Try "Thread.sleep(5000)", because the method sleep is defined in Thread class. OR use static import .

If you extends Thread then it should not be compiler error

Thanks,

Its true try this, import static java.lang.Thread.*; and you will surel get the required output rather the error will no more exist
