Java Program to Illustrates Use of Static Inner Class
Here, we will demonstrate the usage of static inner class using the Java program. Before diving deep into the topic, let us get acquainted with the term Static Inner Class . Static Inner Class An inner class is the one, which is defined within another class. A Static Inner Class is a nested class that is a static member of the outer class. Other static members can be used to access it without first instantiating the outer class. A static nested class lacks access to the instance variables and methods of the outer class, much like static member’s java. Example ...
Read MoreJava Program to illustrate the Usage of Hexadecimal
Here, the usage of Hexadecimal shall be demonstrated through the Java Program. Let us get acquainted with the term Hexadecimal before seeing a Java program. The Hexadecimal is a type of number system that has a base value of 16. There are 16 symbols representing hexadecimal numbers. These symbols or values are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. Each digit represents a decimal value. The hexadecimal numbers from 0 to 9 are equivalent to decimal numbers from 0 to 9. Further, A represents 10, B represents 11, C represents ...
Read MoreJava Program to Illustrate the Availability of Default Constructor of the Super Class to the Sub Class by Default
Here, we will demonstrate the availability of the default constructor of the super class to the sub class by default through Java Program. Before diving deep into the topic, let us get acquainted with the term Constructor, Super class, and subclass. Constructor A special method in Java is considered for the initialization of an object. The name of the constructor is the same as the class name and it does not return anything. A default constructor is invoked by itself whenever an object is created using a new keyword. There are following three types of constructors in Java ...
Read MoreMinimum steps to determine the subsequence with max 1s based on given conditions
The aim of this article is to implement a program to find minimum steps to determine the subsequence with max 1s based on given conditions. So as we all know, a one-dimensional array containing characters that is terminated by a null can be used to define a string. Given is a string Str of length K, wherein K is always even, and contains the characters "0, " "1, " and "?" Divide the string to two separate strings, let's call them Str1 and Str2, each of which is going to include the characters at the even values of Str and ...
Read MoreMinimize count of repositioning of characters to make all given Strings equal
The aim here is to determine whether it would be feasible to make all of the strings identical in any amount of operations provided an array Str of strings with size n. Any element can be taken out of the string and put back in at any point in the same or another string all in one action. Return "Yes" if the strings are able to be made to equal one another, and "No" if not, along with the fewest number of operations necessary. Problem Statement Implement a program to minimize count of repositioning of characters to make all given ...
Read MoreCount of strings to be concatenated with a character having frequency greater than sum of others
Our main aim here is to determine the most strings that are capable of being concatenated to ensure that just one letter has a frequency that exceeds the total of all the other characters, provided an array called arr[] containing M strings. Before going further, let's understand some basic concepts of array and string. The array is nothing but a group of identically data-typed elements held in consecutive memory sections. The array in the C programming language has a fixed size, which means that once the size is specified, it cannot be changed; you cannot shrink or extend it. Let's ...
Read MoreJava Program for array rotation
An array is a linear data structure that is used to store a group of elements with similar datatypes. It stores data in a sequential manner. Once we create an array we can't change its size i.e. it can store a fixed number of elements. The array comes with a vast application and use case. Also, we can perform numerous operations on arrays. This article will help you to understand the basics of arrays and also, we will make java programs to perform right and left rotation operations on arrays. Java Program for Array Rotation First, let's understand the term ...
Read MoreJava multiplyExact() in Math
In Java, multiplyExact() is an in-built static method of the Math class that accepts two arguments and returns their product as a result. This method can accept values of either integer or long type. One important point to note is that it may throw an exception if the produced result overflows the size of integer. After knowing the functionality of multiplyExact() in Java, one question that may pop into one's mind is that we can also use '*' operator to multiply two operands then why do we need multiplyExact() method. We are going to answer this question and also, explore ...
Read MoreIntUnaryOperator Interface in Java
IntUnaryOperator Interface, a functional interface of Java that performs an operation on a single integer-valued operand and also returns an integer value as a result. Since it is a functional interface, we can use it as an assignment target for the lambda expressions or method references. Here, the functional interface means an interface that contains only a single abstract method and exhibits single functionality. Some examples of functional interfaces are Predicate, Runnable, and Comparable interfaces. The IntUnaryOperator interface is defined in the 'java.util.function' package. In this article, we are going to explore the IntUnaryOperator Interface and its built-in methods with ...
Read MoreSort array of strings after sorting each string after removing characters whose frequencies are not a powers of 2
In this problem, we need to remove the characters from the string whose frequency is not the power of 2. After that, we need to sort each string of the array in non-increasing order. Problem statement- We have given an array arr[] containing total N strings of different lengths. We need to remove the character from the string if its frequency is not the power of 2. After that, we need to sort each string Sample examples Input – arr[] = {"abde", "cpcc", "ddddd", "kk"} Output – edba, p, kk Explanation In the string ‘abde’ string, all characters' frequency is ...
