Java Program for range LCM queries
Ranging a query is a common database current interest operation present in data structure to restore all the records where the output value lies between an upper and lower boundary. This process works with some input data, to structure them in an efficient manner on any subset of a particular input. The range function, denoted as range(), is used to iterate a for loop over a series. We need to declare the start as 0 at the beginning of a process. If somehow we miss this step, the process will run and iterate the loop until the end (-1). A ...
Read MoreJava Program to show the Nesting of Methods
Nesting of methods is a hybrid function calling method in Java, which can call another method in the same class. There are two types of nested classes are available in a Java environment. Non-static nested class (also known as , the inner class) Static nested class A non-static nested class (or, inner class) is a defined class within a particular class. It also contains some outer classes with some access authorities. In this method, we can use "." operator to create the instance of the inner class by using an outer class. On the other hand; a static ...
Read MoreJava Program to Separate the Individual Characters from a String
In the field of computer science, the string is a collection of a continuous character data sets. Here in this particular problem we will use some spaces to execute the logic. The individual characters present here in the string can be accessed through its index to perform the code. Here is a general flow to build a logic code to separate the individual characters from a string in a Java environment. Define a string with characters. Print the individual characters present from a given string. Set an initial to zero. Print the string by using the function string.charAt(i). Iterate ...
Read MoreJava Program to Show Time By Rolling Through Hours and Months
The credibility of an efficient coding language depends upon how well it can manage the date and time. In a Java Virtual Environment we get some inbuilt facilities like date, time and calendar to handle the problem related to date and time. java. until date class - In Java, there are many contains those are very important for the program. Date class deals with the operation about the date and time. They are those type of classes which comes with the feature of cloneable, Serializable and comparable interfaces. Extract the current date and time - There are two types ...
Read MoreJava Program to Illustrate the usage of Octal Integer
Octal Integer is a number system having a base of 8 and digits from 0 to 7. Int data type is taken into account to store an octal number. The usage of the Octal number system is to be discussed here − Converting decimal to Octal Converting octal to decimal. Conversion from a Decimal number system to an Octal Number system Basics of Conversion To convert any decimal number into its equivalent octal number: Keep dividing the decimal number by the base of the octal number system which is 8 till the quotient 0 is received. Remember ...
Read MoreJava Program to Search User Defined Object From a List By using Binary Search Comparator
Java comparator interface used to sort Java objects. A comparator class in Java compares the different objects (Obj 01, Obj 02) by invoking the "java. util. comparator". In this method the objects can be compared on the basis of the return value. It can be positive, equal or negative in comparison. The process provides user multiple sorting sequences. There are lots of method by which we can perform the comparison between two methods. public int compare class (obj 1, obj 2) - Perform comparison between two objects. public Boolean equals (obj) - Compare current object with specified object. ...
Read MoreJava Program to Illustrate a Method with 2 Parameters and without Return Type
A method without a return type is termed a void method since it returns nothing. This method can accept multiple parameters. In this tutorial, we will implement Java programs illustrating a method with two parameters and without return type. First of all, we are going to get acquainted with the syntax, examples, and, finally implementation. Syntax public static void method_name (int parameter1, int parameter2) Here, public − It is the access specifier specifying who can access this method. static − It is mandatory to make the method static to avoid errors. void − it denotes that this method returns ...
Read MoreJava Program to Get Year from Date
In our day to day life, there is a huge data being generated in this real world. Among the information generated, Dates are generally used for various things such as scheduling an appointment, planning for day-to-day activities. While working with dates in programming, extracting the year from a specific date can be a common task. We can extract the Year from a particular Date using different in-built functions in Java programming language. In this article we will be discussing different approaches for extracting year from a particular date. Example Input: "13-07-2000" Output: 2000 Example Input: "1997/07/13" Output: 1997 ...
Read MoreJava Program to Find G.C.D and L.C.M of Two Numbers Using Euclid\'s Algorithm
Euclid’s Algorithm is an efficient algorithm which helps us to find G.C.D and L.C.M of two numbers. In this article, we are learning to write a Java program to find the G.C.D and L.C.M of two numbers using Euclid’s Algorithm. G.C.D. of two numbers G. C. D, known as Greatest Common Divisor is the highest common factor that divides the two given numbers exactly. Now let us look into an example and calculate the G.C.D of a two numbers. Factors − In mathematics, Factors are the numbers that can divide a given number. Ex − 8 can be divided ...
Read MoreJava Program to Find Chromatic Index of Cyclic Graphs
Chromatic Index of a graph is the parameter which indicates the minimum number of colours needed to colour all the edges of graph such that no two edges sharing the common vertex have same coloured edge. In this article, we will discuss how to find the chromatic index of cyclic graphs using the Java programming language. What is a Cyclic Graph? Cyclic Graph is a graph which consists of at least one cycle path in that particular graph. Cyclic path is a path that starts from a specific node and ends at the same node. What is Graph Colouring? ...
