No, In Java int cannot be null. There are some primitive data types and int is the one of the primitive data types in Java programming. The default value for an int data type is 0 and it cannot not be null. The different primitive data types have their different default values, but the objects in Java can be null. There is no null reference concept for the primitive data types (such as int, float, etc.). Example For example, if you try to assign null to an int variable. It will generate an error. int myInt = null; How ... Read More
In real-world scenarios, you'll often need to query for the nth highest salary. Let's see how to find the second-highest salary in SQL. Example Consider a sample table named Company with columns Employee and Salary: Table Name: Company Employee ... Read More
In SQL, date and time values are handled using specific data types, such as DATE, DATETIME, TIMESTAMP, etc. Each database management system (DBMS) may have its conventions for date formats, so understanding how to specify and use these formats is essential for working with dates in SQL. The following are the data types to handle date and time in SQL: DATE: Stores date values (year, month, day). DATETIME: Stores date and time values (year, month, day, hour, minute, second). TIMESTAMP: Stores date and time values, ... Read More
Stacks are a fundamental data structure in computer science, often used for their Last-In-First-Out (LIFO) properties. One interesting problem that can be encountered while working with stacks is checking whether the elements of a stack are pairwise consecutive. In this article, we will learn to solve this problem using Java, ensuring an efficient and clear solution. Problem Statement Given a stack of integers, the task is to determine if the elements of the stack are pairwise consecutive. Two elements are considered consecutive if they differ by exactly 1. Input 4, 5, 2, 3, 10, 11 Output Are elements pairwise consecutive?true ... Read More
In Java, handling strings with quotes can be managed by checking and manipulating the string’s start and end. This example demonstrates how to remove double quotes from both the beginning and end of a string. Problem Statement Given a string enclosed in double quotes, write a Java program to remove these enclosing quotes. The result must be the original string without the enclosing double quotes. Input String with double quotes= "Demo Text" Output String after removing double quotes = Demo Text Steps to remove the leading and trailing quotes from a string Below are the steps to remove the leading ...

In this article, we will learn how to retrieve and set client information properties in a MySQL database connection using the getClientInfo() method from the Connection interface in JDBC. The program demonstrates how to establish a connection to a database, set custom user credentials as client information properties, and then retrieve and display those values. Steps to use the Java Connection getClientInfo() method Following are the steps to use the Java Connection getClientInfo() method − Register the MySQL driver using the DriverManager.registerDriver() method. Establish a connection to the MySQL database using DriverManager.getConnection(). ... Read More
In this article, we will learn how to place a component, specifically a button, in the bottom-right corner of a Java Swing application using the BorderLayout manager. The BorderLayout is one of the most commonly used layout managers in Java, and it allows you to place components in five different regions: North, South, East, West, and Center. We will demonstrate how to use BorderLayout to ensure the component is placed precisely in the bottom-right corner of the window. Steps to place the component in the bottom-right corner Following are the steps to place the component in the bottom-right corner with ... Read More
In this article, we will learn how to generate and print all distinct permutations of a given string using Java. Permutations are rearrangements of characters in a string, and this program will ensure that no duplicate permutations are printed. The method works by checking each rearrangement and avoiding any repeats. Problem Statement Write a program in Java to print distinct permutations of a given string − Input my_str = "mnqm" Output The distinct permutations of the string are[mnqm, nmqm, nqmm, mqnm, qmnm, qnmm, mqmn, qmmn, mnmq, nmmq, mmnq, mmqn] Steps to print distinct permutations of a string Following are the ...

In this article, we will learn how to convert a Properties list into a Map in Java. The Properties class is commonly used to store key-value pairs, but sometimes you may need to work with these pairs in a Map structure. We will demonstrate how to take the properties and convert them into a HashMap. Problem Statement Write a program in Java to convert the properties list into a Map structure − Output Key and Value of the Map... P: 1 Q: 2 R: 3 S: 4 T: 5 U: 6 V: 7 Steps to convert the properties list into ... Read More
