Class Class is the collection of similar type of objects which have some common properties. Class is a concept which is implemented by object. Class is a blueprint of java program from which we create object, then object is instance of class. We can also say that class is a collection of variables and methods. …
A unique number is a number in which no digit is repeated. For example: 102452 is not a unique number as 2 is repeated twice while 2374 is a unique number. So in this article I am sharing the C++ program that check if a number is unique or not. Also Read: C++ Program to …

Converting one data type to another data type is known as type casting. Type Casting in Java is of two types i.e. Implicit Type Casting which is also known as Automatic Type Casting and Explicit Type Casting. Implicit or Automatic Type Casting In this, smaller data type is converted to bigger data type which is also …
Data Types in Java Used to represent the type of memory allocation. Used with variables and methods. These are fixed. Primitive Data Types Primitive data types are defined already by the programming language. In Java there are 8 primitive data types. Non-Primitive Data Types Non-Primitive data types are defined by the user. They are Class, …
Here you will learn about prim’s algorithm in C with a program example. Prim’s Algorithm is an approach to determine minimum cost spanning tree. In this case, we start with single edge of graph and we add edges to it and finally we get minimum cost tree. In this case, as well, we have n-1 …
Variable is nothing it is just the name of memory location. While declaring variables we must follow rules given below. Rules for Declaring Variables in Java 1. Variable name must bound with data type. It means while declaring a variable we must specify its data type. Ex: int x=10; 2. Reserve word or keywords cannot …

JVM is responsible for taking .class file and converting that .class file in machine code instructions that can be executed by microprocessor. It’s not a machine, it’s a program. JVM verifies the code before execution (Sandbox Security). JVM is platform dependent and it is heart of Java language. There are four phases of JVM Load …
