What exception type does the following statement throws?

Explanation / Answer

i) String message = "hello";
    System.out.println(message.charAt(5));

trying to access 5 which is out of bound so Exception is ArrayIndexOutofBoundException

ii) double[] array = new double[7];
System.out.println(array[7]);

trying to access 7 which is out of bound so Exception is ArrayIndexOutofBoundException

iii) JButton bt;
bt.setText("submit");

NullPointerException because bt object not initialized.

c) statement to draw circle with radius 15 centered at (40,40) given g

drawCircle(g, 40, 40, 5);
