You will not be allowed to write during the first 15 minutes. This time is to be spent in reading the question paper. The time given at the head of this Paper is the time allowed for writing the answers. This Paper is divided into two Sections. Attempt all questions from Section A and any four questions from Section B. The intended marks for questions or parts of questions are given in brackets [ ]. SECTION A (## Marks) Attempt all questions Question 1 (a) Give the difference between :(1) Default Constructor and Normal Constructor (2) Multilevel Inheritance and Multiple Inheritance. (3) Instantiation and Initialization. (b) What is Light weight Code and Spaghetti code? (c) Write an expression in Java for ( ( ( ) ) )+ (d) Give example of any 5 lexical unit of a Java program. (e) What is the result produced by the following expression when int a=5, double b=3.01, int x=0 Show the working steps. (i) x+ = ++x++++b - x; (ii) y = a+++++b+++a; Question 2 (a) What are different techniques of exception handling ? (b) How many types of Java Programs are there ? Name all the categories. Question 3 Define the following Terms :a) Abstract class b) Absurd Value c) Coercion d) Delimeter e) Dot (.) Operator f) Early Binding g) Infinity h) Hybrid Inheritance i) Integral Promotion j) Label k) Intrinsic data types l) Message passing m) Multi-threading n) Mutator method o) NaN p) Reusability q) Setter method r) Truncation s) WORA Question 4 Explain the following keywords used in a Java program : a) abstract b) assert c) enum d) extends e) implements f) instanceOf g) interface h) native Question 5 (a) What is the difference between local variable and instance variable? [2] (b) Will this program compiles successfully? public class CodingExamples { public static void main(String args[]) { System.out.println(1); http://javaconceptoftheday.com/ System.out.println(2); } } (c) What Are Access And Non-Access Modifiers In Java? Question 6 - What will be the output of the following program segment? (i) String st = Duplication ; System.out.println(st.indexOf(st.charAt(4))); (ii) int a = 10; if(a>10 && a<9) a++; else a-- ; System.out.println(--a); (iii) int a= 7, b = 3,c; if (a>b || a ! = b) c = ++a+--b; System.out.print(c+ - +a+ - +b); (iv) int i=2,x=0; for(i=1 ; i<=4 ; ++i) ; {System.out.print(++x); } SECTION B (## 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 7 - A Financial Company announces a plan for their customers on Fixed Deposit scheme as per the following criteria :No.of Days Rate of Interest/p.a. Bonus Amount in Rs. Upto 90 Nil 500 Next 270 7.5 % 2000 Next 360 9.33 % 5000 Rest of the Days 11.10 % 9000 Input Customer name, Fixed Deposit amount and number of days for which FD is to be made.
