Having doubt on static

[Rajesh k Jha]

In the code given i just want to know that whenever i call any method
from the public static void main() it must be static or not,
As it has created some confustion, So far as i have read we cant call
any non-static method or variable from static method..Please elaborate this part

class TestThread extends Thread{
public void restart()
{
startMe();
}
public static void startMe()
{
// Some magic code here
}
public static void main(String[] args)
{
TestThread t1=new TestThread();
t1.start();
t1.restart();
}
}

Rakesh, you can call any non-static methods or fields from static methods (like main) but you need an instance of the class to do that. You can't access non-static members from a static method directly.

Also please Use Code Tags when you post a source code...

You can call static method using the full qualified name:

ClassName.methodName(...)

or using the instance of the class:
new ClassName().methodName();

When you invoke method from within the main method that method must be static if you do not have the instance of the enclosing class.
