Steps to get date for all the days of the current week Following are the steps to get date for all the days of the current week − First we will import the DayOfWeek and LocalDate from java.time and Arrays class from java.util. We will get the current ... Read More
In this article, we will learn to display a table with columns in the output using Formatter in Java. The table will have headings and show different calculations of an array of floating-point numbers. The first column will display the original number, the second will display the number rounded up, and the third will display the number rounded down. Problem Statement Write a Java program to display a table with columns in the output using Formatter. Input double arr[] = { 1.7, 2.5, 3.1, 4.5, 5.7, 6.9, 7.7, 8.9, 9.1 }; Output The point list...

In this article, we are going to see how to display Floyd’s Triangle using Java. Floyd's triangle is a popular right-angled triangular array consisting of natural numbers. It is formed by starting with the number 1 at the top of the triangle, and then incrementing each subsequent number by 1 as you move down the rows of the triangle. The first row contains only 1 number which is 1 itself and each subsequent row contains 1 more number than the previous row. The triangle has n rows where n can be any positive whole number. The total number of values in ... Read More
In this article, we will fill elements in a char array using Java. We will be using the Arrays.fill() method to fill it with a specific character. This method allows us to assign a single character value to all elements in the array. We will fill the array with the character 'A' and then print the array using Arrays.toString() to display its contents in a readable format. Problem Statement Write a Java program to fill elements in a char array − Input charValue = 'A' Output The char array content is: [A, A, A, A, A] Steps to fill elements in a ... Read More
In this program, we will establish a connection to a MySQL database and check the current auto-commit setting using the getAutoCommit() method from the Connection interface. We will first disable the auto-commit feature using setAutoCommit(false) and then retrieve the current auto-commit status with getAutoCommit() to verify if it has been successfully disabled. Steps to use the getAutoCommit() method Following are the steps to use the getAutoCommit() method − First, we will import the required java.sql.Connection and java.sql.DriverManager packages. We'll establish a connection to a MySQL database using the DriverManager.getConnection() method. ... Read More
In this article, we will prompt the user to input an integer, and the entered value will be displayed back to them. To achieve this, we will use the Scanner class from java.util package, which allows us to read user input. Specifically, the nextInt() method of the Scanner class will be used to read the integer input from the user.Problem Statement Write a program in Java to accept an integer from the user and print it − Input Enter an integer: 2 Output Given integer is :: 2 Steps to accept an integer from the user and print it Following are ...

In object-oriented programming, private methods are functions that act as access modifier within a class designed only for internal use and not accessible from outside the class. The functionality of private methods is primarily meant for encapsulation which means that they are hidden to prevent unwanted modifications and misuse. Working of Private Methods In Python, the convention to denote private methods is "_". We just need to prefix the method name with a single underscore (_) or, double underscores (__). Single underscore(_) : To indicate that ... Read More
In Python, to sort a CSV file by multiple columns, we can use the 'sort_values()' Method provided by the Python Pandas library. This method is used for sorting the values by taking column names as arguments. Some of the common methods for sorting a CSV file by multiple columns are as follows. sort_values() : To sort a DataFrame by multiple columns. sort_values() without inplace : To sort a DataFrame by ...

In Python, a dictionary doesn't allow duplicate keys or repeated keys. So, we can use defaultdict from the Collections module. As it can store multiple values for the same key in the form of lists or any other data structures. 'defaultdict' from 'collections' Module The subclass of the built-in dict class that allows us to provide a default value for a key that doesn't exist is known as defaultdict. A function that returns the default value for new keys is known as 'default factory', and if you want to pass this default factory, we can use a list which allows storing ... Read More
