JAVA Threads What will be the output of the following program code?public class Test implements Runnable{ public static void main(String[] args){ Thread t = new Thread(this); t.start(); } public void run(){ System.out.println("test"); }} The program does not compile because this cannot be referenced in a static method. The program compiles fine, but it does not print anything because t does not invoke the run() method The program compiles and runs fine and displays test on the console.
