Getter and Setter in Java
Getter and setter are two special methods in Java that allow accessing and modifying data members' values. They are mostly used in encapsulation and data hiding to protect our sensitive data from unauthorized access. In encapsulation, we group related data and behavior together in a class and hide the implementation details from the outside world. Data hiding means preventing direct access of the members of class from the internal state of an object. In this article, we will explain what getter and setter methods are in Java and how they are useful in data hiding. Getter and Setter methods The ...
Read MoreExtract substrings between any pair of delimiters
Delimiters are the characters that separate a string from other characters, for example in a sentence in our normal day to day reading activity, we find out the different words because it is separated by spaces. We have () parenthesis as main delimiters in mathematical and regular expressions. The concept of substrings and their manipulation is very important in programming, especially in c which is a language used to write compilers and assemblers. The delimiters are identified in the string and the characters after the starting delimiter are copied into another variable, until the ending delimiter. The == ...
Read MoreLargest number not exceeding N that does not contain any of the digits of S
The challenge of finding the largest number not exceeding a given number N and not containing any of the digits in a string S is a problem that involves string manipulation and number theory. The goal is to determine the greatest possible number that is less than or equal to N while also excluding all of the digits found in the string S. For instance, consider a scenario where N is equal to 1000 and S is equal to "42". In this scenario, the largest number not exceeding N and not containing any of the digits in S would be ...
Read MoreRemove all the occurrences of a character from a string using STL
STL basically stands for Standard Template Library, which is a collection of pre-written code frequently used in Data structures and Algorithms. It was developed in the early 1990s by Meng Lee and Alexander Stepanov. It consists of mainly three components known as containers, algorithms and iterators. Containers are objects that stores and manipulate data such as list, vector, set, map and stack. Algorithm are functions which works on the data stored in the containers such as searching, sorting and also manipulating data. Iterators are object that navigates through the elements of a container easily. STL has became an ...
Read MoreIntFunction Interface in Java with Examples
In Java, the IntFunction interface is a functional interface that represents a function that accepts an integer type value as an argument and returns a result of any data type. 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 IntFunction interface is defined in the 'java.util.function' package. In this article, we are going to explore the IntFunction Interface and its built-in methods with the help of example programs. IntFunction Interface in Java The IntFunction Interface has a ...
Read MoreCount removal of pairs required to be empty all Balanced Parenthesis subsequences
C compiler treats a string as an array of characters, so it is easy to remove characters of a string based on their position. The first and last position of the string have to be checked for the presence of parenthesis and have to be removed. The string can be copied into another variable and presented. There are many predefined functions in C that can be used effectively to manipulate strings. Removing a character from the starting or ending position is easily achieved in C with the help of the functions. Removing starting and ending paranthesis from string ...
Read MoreCount of primes after converting given binary number in base between L to R
The title "Count of primes after converting given binary number in base between L and R" refers to a math problem that involves converting a binary number into a base between L and R and then counting the number of prime numbers that come from the conversion. In math, a prime number is a whole number that is greater than 1 and can only be divided by 1 and itself. To turn a binary number into a number with a different base, the number has to be written in a different number system. The number system's base is the number ...
Read MoreHow to validate GST (Goods and Services Tax number using Regular Expression?
The government issues a unique identification number known as a GST number to businesses and individuals who have registered for GST. As part of the validation procedure, the GST number is checked for correctness and legitimacy. The format of the number is frequently checked during the verification process to make sure it is correct and conforms to the format needed by the tax authorities of the relevant country. In order to confirm the validity of the number and that it belongs to the person seeking it, the verification phase may also involve cross-referencing it with the database of the tax ...
Read MoreInteger.valueOf() vs Integer.parseInt() with Examples
In Java, both Integer.parseInt() and Integer.valueOf() methods are used for the conversion of a String into an Integer. These static methods belong to the Integer class of java.lang package and throws a NumberFormatException if the string is not a valid representation of an integer. But wait, the question arise here is that why Java provides two methods with the same functionality. Although they are used to serve similar jobs, there exist a few distinctions between them in terms of syntax and return type. In this article, we are going to explain the difference between Integer.parseInt() and Integer.valueOf() methods with ...
Read MoreInteger.MAX_VALUE and Integer.MIN_VALUE in Java with Examples
The Integer class of Java provides two constants named Integer.MAX_VALUE and Integer.MIN_VALUE represents the maximum and minimum possible values for an integer variable in Java. The actual value of Integer.MAX_VALUE is 231 -1 which is equivalent to 2147483647 and the actual value of Integer.MIN_VALUE is -231 which is equivalent to -2147483648. For our convenience, instead of writing this big whole number in our program, we use their constant representation. This article aims to explore the utility and how to use Integer.MAX_VALUE and Integer.MIN_VALUE in our Java programs. Examples of Integer.MAX_VALUE and Integer.MIN_VALUE in Java In this section, we ...
