Section-A [40 Marks]

Question 1. (a) Write an expression in java for cos x+y2. 
(b) Write the primitive data types that represent the integer numbers. 
(c) What is the return type of a constructor? What will not be the return type of a function, if it returns a value? 
(d) Write the following condition using ternary operator:  If amount is greater than 1000 and less than 10000, the commission is Rs. 4000 else it is 0.
(e) Write two advantages of using functions in a program.

Question 2. (a) Which unit of the class get called, when the object of a class is created? 
(b) How many value can be returned from a function? 
(c) If m = -14 and n = -3, what is the value of m % n? 
(d) Define a method named ‘calculator’ that accepts two short type variables as its arguments and returns an integer value. 
(e) State the total size in bytes of each of the arrays – 
(i) a of char data type (ii) p of float data type

Question 3. (a) Write a java statement to create an object ‘barbie’ for a class ‘toy’. 
(b) Write the output (assume a as 0).  if (a > 0 && a < 20) a++; else a – -; System.out.print(a);
(c) Write the output of the following –  System.out.println(Math.rint(Math.abs(-15.6)));
(d) What is logical operator? Name any two logical operators. 
(e) What is the purpose of default in a switch construct

Question 4. (a) Write the output of –  boolean k; k =(“BLUEJ”.length()>”JAVA”.length())? true:false; System.out.println(k);
(b) Write down the syntax for the following –  To return the first occurrence of ‘a’ in the word “applications”
(c) Convert the following into for loop- 
int h=0,j=4;
while(j>=0)
{
h=h+j;
j – =2;
} S
ystem.out.println(h);
(d) Define the keyword public in the statement public static void main(). 
(e) Can an identifier name be same as that of a keyword?

Section -B [15x 4 = 60 Marks]
[Attempt all questions from this Section]
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 5. Define a class Candidate with the following descriptions:
Data Members:

• RNo(Registration Number) of type long
• Name of type String
• Score of type float
• Remarks of type String Member methods:
(i) A function ENTER() to allow user to enter values for Rno, Name, Score
(ii) A member function Remark() to assign the remarks as per the score obtained by a candidate. Score range and the respective remarks are shown as follows:

(iii) A function DISPLAY() to allow user to view the content of all data members. Also create a main() method to create an object and call the functions. [15

Question 6Use switch statement, write a menu driven program to:
(i) To find and display all the factors of a number input by the user (including 1 and excluding number itself.) Example: Sample Input : n=15. Sample Output : 1,3,5
(ii) To find and display the factorial of a number input by the user(the factorial of a non-negative integer n ,denoted by n!, is the product of all integers less than or equal to n. Example: Sample Input : n=5 Sample Output : 5!=1×2×3×4×5=120. For an incorrect choice, an appropriate error message should be displayed.

Question 7. Write a program to input 10 numbers into a float type array and arrange the numbers in descending order using Bubble Sorting technique.

Question 8. Write a program to input two characters from the keyboard. Find the difference (d) between their ASCII codes. Display the following messages:
If d=0 : both the characters are same.
If d<0 : first character is smaller.
If d>0 : second character is smaller.
Sample Input :
C
P
Sample Output :
First character is smaller (since d= (67-80) = -13)
