Even pasted it in from other solutions, that passed the 5th requirement. Still not working ?

/*
1. Create 5 different threads that differ from Thread:
1.1. Thread 1 must run indefinitely;
1.2. Thread 2 should display "InterruptedException" when an InterruptedException occurs;
1.3. Thread 3 should display "Hurray" every half second";
1.4. Thread 4 must implement the Message interface. When the showWarning method is called, the thread should stop;
1.5. Thread 5 should read numbers from the console until "N" is entered. Then it should display the sum of the entered numbers.
2. In a static block, add your threads to List<Thread> threads in the specified order.
3. The threads should not start automatically.
Hint:
Thread 4 can be checked using isAlive()
Requirements:
1. The Solution class's static block must create 5 threads and add them to the threads list.
2. The threads in the threads list should not start automatically.
3. Thread 1 in the threads list must run infinitely.
4. Thread 2 in the threads list should display "InterruptedException" when an InterruptedException occurs.
5. Thread 3 in the threads list should display "Hurray" every half second.
6. Thread 4 in the threads list must implement the Message interface. When the showWarning method is called, the thread should stop.
7. Thread 5 in the threads list should read numbers from the console until "N" is entered. Then it should display the sum of the entered numbers.
