7 7 Sample Questions: Q1) Answer of the following: 1- What are different between Public and private of access Specifiers in JAVA? 2- What is method overloading? Q1) Answer: 1-1)Public can be accessed by other class member that is initialized outside the class. A public member can be accessed from anywhere even outside the namespace. 2) Private: can be accessed only inside the classes. The private members cannot be accessed outside the class 2-Method overloading: is the same method name with different type of parameters or different set of parameters is known as Method Overloading.. Q2) Select the correct answer from the following: 1- Which of the following will be the correct output for the JAVA program? namespace ConsoleApplication class Sample int i; Single j; public void SetData(int i, Single j) this.i = i; this.j = j; public void Display() Console.WriteLine(i + " " + j); class MyProgram

8 8 static void Main(string[ ] args) Sample s1 = new Sample(); s1.setdata(36, 5.4f); s1.display(); A B C D Which of the following statements is correct about the JAVA code?. class Student s1, s2; s1 = new Student(); s2 = new Student(); A. Contents of s1 and s2 will be exactly same. B. The two objects will get created on the stack. C. Contents of the two objects created will be exactly same. D. The two objects will always be created in adjacent memory locations. Q2)1- Answer: B 2- Answer: c Q3) Write complate a program to Create a class Rectangle has attributes such as length and width. Depending upon the design, it may need ways for accepting the values of these attributes, calculating the area, and displaying details. Q3) Answer

9 9 using System ; namespace RectangleApplication class Rectangle double length; double width; public void Acceptdetails() length = 4.5; width = 3.5; public double GetArea() return length * width; public void Display() Console.WriteLine("Length: 0", length); Console.WriteLine("Width: 0", width); Console.WriteLine("Area: 0", GetArea()); class ExecuteRectangle static void Main(string[] args) Rectangle r = new Rectangle(); r.acceptdetails(); r.display(); Console.ReadLine(); Q4) Complete the following blanks with suitable word variable directly contains data in the memory are sequences of characters 3- Class definition consists of: Q4) Answer

10 10 1- Value Type 2- Strings 3-1- Class declaration. 2- Inherited class. 3 Fields.4- Constructors Q5) Write method to calculate the sum of the elements in an array. "Main" should be like this: public static void Main() int[] example = 20, 10, 5, 2 ; Console.WriteLine( "The sum of the example array is 0", Sum(example)); Q5)Answer: using System; public class SumArray public static int Sum(int[] example) int total=0; for (int i = 0;i < example.length; i++) total += example[i]; return total; public static void Main() int[] example = 20, 10, 5, 2 ; Console.WriteLine("The sum of the example array is 0", Sum(example));
