1. int w = (int)888.8;2. byte x = (byte)100L;3. long y = (byte)100;4. byte z = (byte)100L;
Suppose you are compiling on a machine with 1-byte chars, 2-byte shorts, 4-byte ints, and 8-byte doubles, and with alignment rules that require the address of every primitive data element to be an integer multiple of the element's size. Suppose further that the compiler is not permitted to reorder fields: padding is used to ensure alignment. How much space will be consumed by the following array? struct { short s; char c; short t; char d; double r; int i; } A[10]; /*10-element array of structs*/
There are five classes class 1, class 2, class 3, class 4 and class 5 in a school. They are one above the other. Class 1 is at the bottom, then class 2 above it and so on. Five videos M1, M2, M3, M4 and M5 are displayed in these given classes. Only one video is displayed in a particular class. Each video is displayed only one time. Video M5 is displayed at an even numbered class. Video M2 is displayed at class 1. Video M1 is displayed at the class just below M5. Video M4 is not displayed at even numbered class. Which of the following statement is not correct? 
interface Base{ boolean m1 (); byte m2(short s);}

which two code fragments will compile?
1. interface Base2 implements Base {}2. abstract class Class2 extends Base { public boolean m1(){ return true; }}3. abstract class Class2 implements Base {}4. abstract class Class2 implements Base { public boolean m1(){ return (7 > 4); }}5. abstract class Class2 implements Base { protected boolean m1(){ return (5 > 7) }}
In the question below, a statement is given, followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested course of action logically follow (s) for pursuing. Statement: Led by a strong response to its first super sports utility vehicle Urus, Italian sports car maker Lamborghini is likely to more than double its volumes in India by the end of 2019, a year ahead of its plan, and cross the milestone of 50-60 vehicles per annum. The company, which began deliveries for Urus in India in September, said the vehicle is already booked for the coming six-nine months in India much like the global markets, and it will help Lamborghini get new. customers into its fold. Courses of action: I. The company is planning not to increase the price of its vehicle despite significant rupee depreciation and wants to protect the attractive price of Urus for prospective buyers.  II. The super sports utility vehicle will drive volumes, super sports cars such as Huracan and Aventador will grow by 8-10%. The company feels an 8-10% growth in the segment is a realistic expectation in spite of the challenges.  III. More than 68% of Urus buyers are first-time Lamborghini buyers and makers are sure that this will have a positive rub-off effect on the super sports car segment too.
Which of these methods is not defined in both Byte and Short wrappers?
Following declaration of an array of struct, assumes size of byte, short, int and long are 1, 2, 3 and 4 respectively. Alignment rule stipulates that n-type field must be located at an address divisible by n. the fields in a struct are not rearranged, padding is used to ensure alignment. All elements of array should be of same size. Struct complx                 Short s                 Byte b                 Long l                 Int i End complx Complx C[10] Assuming C is located at an address divisible by 8, what is the total size of C, in bytes?
With reference to 8085 microprocessor, which of the following statements are correct? 1. INR is 1-byte instruction 2. OUT is 2-byte instruction 3. STA is 3-byte instruction

Given below are three quantities named A, B and C. Based on the given information, determine the relation among the three quantities. Total number of pupils in three classes of a school is 1288. The ratio of children in three classes X, Y, Z is 39 : 64 : 58. In class X number of boys are 26 less than number of girls. Number of boys in class Y is 67.83% more than the number of boys in class X. And, girls in class Z are 25.36% less than the number of girls in class Y. (In calculating number of boys and girls, the decimal value must be rounded off to nearest whole number). Quantity A: Number of boys in class Z. Quantity B: Number of girls in class X. Quantity C: Number of girls in class Y.
