initializing thread

[saravanan ragunathan]

   
Thread t;
t=new Thread(new Ex1());
t.start();
 

the above code is executed successfully
but for experimental purpose when i write the below code
to start only the last thread i have created..it will generate
compilation error("variable t might not have been initialized")
is there is any problem in this

Thread t;
for(int i=0;i<10;i++)
{
t=new Thread(new Ex1());
}
t.start();

What will happen if you change that 10 into a 0? The compiler thinks in a similar way. It can't guarantee that t will have a value after the loop.

It's Just a Compilation error: The local variable t may not have been initialized

unless any reference is target of assignment operator, compiler would not allow to use its L value..

simply assign null and then proceed

		Thread t = null;  

needless to say that there is a chance of NullPointer incase it bypasses for loop
