The reason behind it that when two or more threads try to update the value at the same time then it may not update properly. b) virtually View Answer, 6. There are the following types of binary tree in data structure: There are many ways to implement binary tree. In this section, we will learn the implementation of binary tree data structure in Java.Also, provides a short description of binary tree data structure. All of the constants are resolved at compile-time instead of run time, unlike the regular constant. It provides code reusability for every function. An example of runtime polymorphism is function overriding. c) Java A compile-time occurs if an implicit conversion is not possible or if the number of arguments is incorrect. d) All class student, topper and average together can show polymorphism c) Anonymous class c) 2 Vector is thread safe. Object being passed to a copy constructor ___________ Ltd. Also this Deletion at the end of the vector needs constant time but for the rest it is O(n). Python allows polymorphism. d) Copy an object so that it can be passed to a class It means it checks the valid casting of the variables at the run time, and if the casting fails, it returns a NULL value. The function to be invoked is known at the run time. C++ includes both low-level programming and high-level language so it is known as a mid-level and intermediate programming language. If the file doesn't have any public class, we can save it with any name, but after compilation, a bytecode file will be generated with the name of the class containing the main method.

Java is an interpreted language, so it will never be as fast as a compiled language like C or C++. Answer: B Explanation: To declare an array in C++, we first need to specify its data type according to requirements such as int or char, afterward that the array's name and the size of the array. Java has a special class library for communicating using TCP/IP protocols. When we say a function is overridden it means that a new definition of that function is given in the derived class. So the correct answer will be B. It is also known as overriding, Dynamic binding and late binding. d) Data binding a) Private data members can never be accessed from outside the class OOPs MCQ on Constructors and Destructors. Hence, the JVM will consider the value of a and b as 60 and 30 concerning the execution order. Just go through them quickly, we will explore them in details later. Embedded Assignment Expression; An embedded assignment expression is an assignment expression in which assignment expression is enclosed within another assignment expression. Run-time polymorphism.

Cloud Computing MCQ (Multi Choice Questions) with Introduction, Advantages, Disadvantages, history of cloud computing, virtualization, software virtualization, hardware virtualization etc. This is a simple program to create an array and then to print it's all elements. It is used to achieve compile-time polymorphism. The function to be invoked is known at the compile time. Binary tree is a tree type non-linear data structure that are mainly used for sorting and searching because they store data in hierarchical form. We can explain compile-time polymorphism through method overloading. d) Program runs and all objects are created There is another way to print the value of constants using constant() function instead of using the echo statement. Following are some basic concept of OOP's. Java Run-time Environment (JRE) is the part of the Java Development Kit (JDK).
