thread class, runnable interface

Runnableはrun methodをもつfunctional interface
constructor of Threadにrunnableを引き渡す

public class Outer {
    public static void main(String[] args) {
        Thread t = new Thread(new Runnable() {
            public void run() {
                System.out.println(" i am run method");
            }
        });
        t.start();       
    }
}
