Kindly provide me the ICSE board exam class X last year paper of Computer Applications……….

Here I am sharing the ICSE board exam class X last year paper of Computer Applications:

SECTION A (40 Marks)
Attempt all questions
Question 1
(a) Name any four tokens of Java. [2]
(b) Give the difference between actual parameter and formal parameter. [2]
(c) What is an identifier? [2]
(d) Write an expression in Java for cos x + 2 2 a b . [2]
(e) What is the result produced by 2 – 10*3 + 100/11? Show the steps. [2]

Question 2
(a) What is the difference between local variable and instance variable? [2]
(b) int x =20, y = 10, z;
What is the value of z in
z = ++x * (y – –) – y ?
Show the steps. [2]
(c) What is the purpose of default in a switch? [2]
(d) Give the difference between linear search and binary search. [2]

(e) What will be the output of the following code?
float x = 7.87;
System.out.println(Math.ceil(x);
System.out.println(Math.floor(x); [2]

Question 3
(a) State the difference between if-else if ladder and switch...case. [2]
(b) Explain the concept of constructor overloading with an example. [2]
(c) What will be the output of the following program segments?
(i) String s = “application”;
int p = s.indexOf(„a‟);
System.out.println(p);
System.out.println(p+s); [2]
(ii) String st = “PROGRAM”;
System.out.println(st.indexOf(st.charAt(4))); [2]
(iii) int a = 0;
if(a>0 && a<20)
a++;
else a-- ;
System.out.println(a); [2]
(iv) int a= 5, b = 2,c;
if (a>b || a ! = b)
c = ++a+--b;
System.out.print(c+ “ ”+a+ “ ”+b); [2]
(v) int i = 1;
while(i++<=1)
{
i++;
System.out.print(i + “ ” );
}
System.out.print(i); [2]

(d) Differentiate between isUpperCase(char) and toUpperCase(char). [2]
(e) What is the difference between a constructor function and a member
function of a class? [2]
(f) What is the difference between a static member function and a member
function which is not static? [2]

SECTION B (60 Marks)
Attempt any four questions from this Section.
The answers in this Section should consist of the Programs in either Blue J environment
or any program environment with Java as the base. Each program should be written
using Variable descriptions/Mnemonic Codes such that the logic of the program is
clearly depicted.
Flow-Charts and Algorithms are not required.

Question 4
Define a class taximeter having the following description:
Data members/instance variables
int taxino - to store taxi number
String name - to store passenger's name
int km - to store number of kilometres travelled
Member functions:
taximeter() -- constructor to initialize taxino to 0, name to “ ”and b to 0.
input() - to store taxino,name,km
calculate() - to calculate bill for a customer according to given conditions
kilometers travelled(km) Rate/km
1 km Rs 25
1 km 6 Rs 10
6 < km 12 Rs 15
12 < km 18 Rs 20
>18 km Rs 25
display()- To display the details in the following format
Taxino Name Kilometres travelled Bill amount
- - - -
Create an object in the main method and call all the above methods in it. [15]

Question 5
Write a menu driven program to find the sum of the following series depending on the
user choosing 1 or 2
1. S=1/4+1/8+1/12.........upto n terms
2. S=1/1!-2/2!+3/3!.......upto n terms
where ! stands for factorial of the number and the factorial value of a number is the
product of all integers from 1 to that number, e.g. 5! = 1 2 3 4 5.
(use switch-case). [15]

Question 6
Write a program to accept a sentence and print only the first letter of each word of the
sentence in capital letters separated by a full stop.
Example :
INPUT SENTENCE : “This is a cat”
OUTPUT : T.I.A.C. [15]

Question 7
Write a program to create an array to store 10 integers and print the largest integer and
the smallest integer in that array. [15]

Question 8
Write a program to calculate the sum of all the prime numbers between the range of
1 and 100. [15]
Question 9
Write a program to store 10 names in an array. Arrange these in alphabetical order by
sorting. Print the sorted list. Take single word names, all in capital letters,
e.g. SAMSON, AJAY, LUCY, etc. [15]
