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

In this article, we will add two long integers in Java and check if the sum causes an overflow, which happens when the result exceeds the maximum value that a long data type can hold, defined by the Long class as Long.MAX_VALUE. If the sum goes beyond this limit, an exception will be thrown to handle the overflow. Otherwise, the sum will be displayed as the result. Steps to add long integers and check for overflow Following are the steps to add long integers and check for overflow − First, we will define two long integers ... Read More
Is it possible to create and run a Java program without any class? The answer is Yes. The trick is to use an enum instead of a Class.Enums are similar to classes, but instead of using the class keyword, we use enum to define them. An enum is used to represent a public static constant. It can have a static main method as well. Steps to write Java program without making classFollowing are the steps to write a Java program without making class −We will start by defining an enum instead of a class. An enum typically represents constants, but it can also ... Read More
In this article, we will understand how to rotate matrix elements using Java. A matrix is a representation of the elements in rows and columns. Matrix rotation is shifting the position of each element of the matrix by 1 position towards its right or left. We will be using two approaches: one where the matrix is rotated based on user input, and another where the matrix is defined within the code. Problem Statement Write a Java program to rotate matrix elements. Below is a demonstration of the same − Input The matrix is defined as 1 2 3 4 5 6 ... Read More
To compile and execute a program in C#, you just need to click the Run button or press F5 key to execute the project in Microsoft Visual Studio IDE.
