2. Provide the output of the following program for the values of y=0 and y=2: public class Test { public static void main(String args[]) { try { System.out.println("calling method a"); a(); System.out.println("return from method a"); } catch(ArithmeticException e) { System.out.println("main: catch"); } finally { System.out.println("main: finally"); } } public static void a() { try { int x=8,y=0; int z=x/y; System.out.println("value of z="+z); } catch(NumberFormatException e) { System.out.println("method a:catch"); } finally { System.out.println("method a:finally"); } }}

3. Explain both overloading and overriding, and provide an example for each.

a. Declare a class called employee having employee_id and employee_name as members. b. Extend class employee to have a subclass called salary having designation and monthly) salary as members. c.
