The "switch" selection structure must end with the default case.
What will happen when you attempt to compile and run the following code? int Output = 10; boolean b1 = false; if((b1 == true) && ((Output += 10) == 20)) { System.out.println("We are equal " + Output); } else { System.out.println("Not equal! " + Output); }
What is the result when you compile and run the following code? public class Test { public void method() { for(int i = 0; i < 3; i++) { System.out.print(i); } System.out.print(i); } }
What will be the output on compiling/running the following code? public class MyThread implements Runnable { String myString = "Yes "; public void run() { this.myString = "No "; } public static void main(String[] args) { MyThread t = new MyThread(); new Thread(t).start(); for (int i=0; i < 10; i++) System.out.print(t.myString); } }
