inta,b;

for (a = 6, b = 4; a <= 24; a = a + 6)

{

if (a%b ==0)

break;

}

System.out.println(a);

whenint y=8

(h) What is an identifier? [2]

(i) Name the wrapper class of char type and boolean type? [2]

(j) Name the two types of constructors.

**SECTION B (60 Marks)**

Attempt any four questions from this Section.

[The answers in this section should consist of the programs in either BlueJ environment

or any program environment with Java as the base.

Each program should be written using Variable descriptions/Mnemonic codes so that

the logic of the program is clearly depicted.

Flow-charts and algorithms are not required.]

**Question 4: [15]**

Write a program to input a number and check and print whether it is a Pronic number or not.

(Pronic number is the number which is the product of two consecutive integers**Examples:**

12 = 3 × 4

20 = 4 × 5

42 = 6 × 7

**Question 5:**

Design a class to overload a function volume() as follows: [15]

(i) double volume (double R) – with radius (R) as an argument, returns the volume of sphere using the formula.

V = 4/3 × 22/7 × R^{3}

(ii) double volume (double H, double R) – with height(H) and radius(R) as the arguments, returns the volume of a cylinder using the formula.

V = 22/7 × R^{2} × H

(iii) double volume (double L, double B, double H) – with length(L), breadth(B) and Height(H) as the arguments, returns the volume of a cuboid using the formula.

V = L × B × H

**Question 6: [15]**

Write a program to input integer elements into an array of size 10 and perform the following operations:

(i) Display largest number from the array.

(ii) Display smallest number from the array.

(iii) Display sum of all the elements of the array.

**Question 7:**

Write a menu driven program to display the pattern as per user’s choice.

For an incorrect option, an appropriate error message should be displayed.

**Question 8: [15]**

Write a program to accept a number and check and display whether it is a Niven number or not.

(Niven number is that number which is divisible by its sum of digits).**Example :**

Consider the number 126.

Sum of its digits is 1+2+6 = 9 and 126 is divisible by 9.

**Question 9: [15]**

Write a program to input 15 integer elements in an array and sort them in ascending order using the bubble sort technique.
