JAVA Threads Analyze the following code:public class Test implements Runnable{ public static void main(String[] args){ Test t = new Test(); t.start(); } public void run() { }} The program compiles, but it does not run because the start() method is not defined. The program compiles and runs fine. The program does not compile because the start() method is not defined in the Test class. The program compiles, but it does not run because the run() method is not implemented. The program compiles, but it does not run because the start() method is not defined.

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. "BeginEnd" is printed. An exception is thrown at runtime. "BeginEndRun" is printed. "BeginRunEnd" is printed. Compilation fails. "BeginEnd" is printed. An exception is thrown at runtime. "BeginEndRun" is printed. "BeginRunEnd" is printed. ANSWER DOWNLOAD EXAMIANS APP
