java - 内部クラスでの不正な static 宣言

Question

import java.lang.*;

class mythread implements Runnable {

    Thread t1;
    String name = "";

    mythread(String thname){

        name = thname;
        t1 = new Thread(this, name);
        System.out.println("Child thread starting" + t1 );
    }

    @Override
    public void run() { 
        for(int i = 5 ; i > 0 ;i--){
            System.out.println("Name Of Thread" + t1 + i);
        }   
    }


    class t {

        public static void main(String args[]) {

            mythread m1 = new mythread("Child Thread 1");
            mythread m2 = new mythread("Child Thread 2");

            try {

            for(int i = 5 ; i > 0 ;i--) {
                System.out.println("Main Thread" + i);
                Thread.sleep(2000);
            }

        }
        catch(InterruptedException e){

            System.out.println("Main Thread Interrupted");
        }


     }
}

        name = thname;

    @Override

            System.out.println("Name Of Thread" + t1 + i);
        }   
    }
} // was missing (for closing class mythread)


class t {

    public static void main(String args[]) {

        mythread m1 = new mythread("Child Thread 1");
        mythread m2 = new mythread("Child Thread 2");

        try {
