JAVA Threads Analyze the following code:public class Test implements Runnable{ public static void main(String[] args){ Test t = new Test(); } public Test(){ Thread t = new Thread(this); t.start(); } public void run(){ System.out.println("test"); }} The program compiles fine, but it does not run because you cannot use the keyword this in the constructor. The program has a compilation error because t is defined in both the main() method and the constructor Test(). The program compiles and runs and displays nothing.
