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 has a compilation error because t is defined in both the main() method and the constructor Test(). The program compiles and runs and displays test. The program compiles and runs and displays nothing. The program compiles fine, but it does not run because you cannot use the keyword this in the constructor.

JAVA Threads What will be the output?class A extends Thread{ public void run(){ for(int i=0; i<2; i++){ System.out.println(i); } }}public class Test{ public static void main(String argv[]){ Test t = new Test(); t.check(new A(){}); } public void check(A a){ a.start(); }} 0 0 None of these 0 1 Compilation error, class A has no start method Compilation succeed but runtime exception 0 0 None of these 0 1 Compilation error, class A has no start method Compilation succeed but runtime exception ANSWER DOWNLOAD EXAMIANS APP
JAVA Threads Given the code. What will be the result?public class Test implements Runnable{ public static void main(String[] args) throws InterruptedException{ Thread a = new Thread(new Test()); a.start(); System.out.print("Begin"); a.join(); System.out.print("End"); } public void run(){ System.out.print("Run"); }} Compilation fails.
