How to easily insert datetime in MySQL?
You can easily insert DateTime with the MySQL command line. Following is the syntax − insert into yourTableName values(‘yourDateTimeValue’); Let us first create a table − mysql> create table DemoTable ( DateOfBirth datetime ); Query OK, 0 rows affected (0.97 sec) Insert some records in the table using insert command − mysql> insert into DemoTable values('1998-01-23 12:45:56'); Query OK, 1 row affected (0.26 sec) mysql> insert into DemoTable values('2010-12-31 01:15:00'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values('2015-04-03 14:00:45'); Query OK, 1 row affected (0.10 sec) Display all records from the table using select statement ...
Read MoreBest way to null check in Kotlin
In any programming paradigm, it is mandatory to check "null safety" in order to prevent runtime errors. In this article, we will see different ways to check "null safety" in Kotlin. Example - Using if…else In most of the programming languages, we have the "if" keyword to check conditions. In Kotlin too, we can use the "if-else" clause to check the null safety of a variable. fun main() { val name="TutorialsPoint.com" //null check if (name != null) { println(name) ...
Read MoreStack and the stack pointer in 8085 Microprocessor
The stack is a LIFO (last in, first out) data structure implemented in the RAM area and is used to store addresses and data when the microprocessor branches to a subroutine. Then the return address used to get pushed on this stack. Also to swap values of two registers and register pairs we use the stack as well.In the programmer‘s view of 8085, only the general purpose registers A, B, C, D, E, H, and L, and the Flags registers were discussed so far. But in the complete programmer’s view of 8085, there are two more special purpose registers, each ...
Read MoreJava Multicasting (Typecasting multiple times) Puzzle
Introduction Java Multicasting known as typecasting multiple times. It is the process of converting a value from one data type to another and it involves multiple typecasting conversions. It allows us to change the data type of a variable to perform operations that would not be possible otherwise. Let us discuss multicasting in Java. We will talk about numeric multicasting to convert between numeric data types. We will also discuss object multicasting to treat subclass objects as superclass objects. We will also provide simple programming examples to understand this topic easily. Numeric Multicasting in Java In this programming example we ...
Read MoreJava Method Parameters
Introduction We know that Java Method Parameters are variables used in method declarations to accept inputs and enable the methods to work with data that are dynamic. Let us discuss the Java Method Parameters and their use in making methods reusable and adaptable. We will discuss the importance of data input, code reusability, and flexibility. We will also explain about the pass−by−value and pass−by−reference by using Java Parameters with basic programming examples. By understanding the article, we hope our readers will understand the importance of the Java Method Parameters as it helps to create essential and maintainable Java programs. Definition ...
Read MoreJava JSON Processing (JSON-P) with Example
Introduction Java programs can operate with JSON data due to the strong Java JSON Processing (JSON-P) API. Web servers and clients frequently exchange data using the lightweight JSON data transfer standard. JSON-P offers the Object Model API and the Streaming API as its two primary methods for processing JSON data. Let us talk about these two strategies and use examples to show how they work and what they can do. We hope that our readers will learn about the Object Model API and Streaming API, together with Programming examples, by understanding this article's explanations on Java JSON Processing (JSON-P) with ...
Read MoreWhat\'s the best RESTful web framework to use with Java
Introduction Let us talk about what’s the best Java RESTful web framework to use with Java language. We know there are a lot of frameworks available but the “Spring Boot” is the best choice among other Java frameworks. Here we will talk about the usage of the RestTemplate and integration of various data formats including JSON, XML, and HTML using the Spring Boot framework. We will also discuss various approaches to handling HTTP requests. We will learn why Spring Boot is the ideal framework for creating RESTful web services in Java by understanding this article. Support of HTTP in ...
Read MoreDoes it make sense to choose JavaScript instead of Java for server-side programming and why
Introduction We know that over a period of time JavaScript has gained popularity for its versatility and it’s easy to use. Java remains a top choice for server-side programming due to its reliability, scalability, and large ecosystem. Let us discuss about why choosing Java as a server-side programming language over JavaScript is a better choice. We will talk about different approaches to explain the strengths of Java. Firstly, we will discuss the stability and robustness of Java by using Spring boot. Then we will explain the scalability and performance of Java. At last, we will explain the advantage of server-side ...
Read MoreIs Java dying at the hands of Oracle What future is there for Java?
Introduction Java is a widely used programming language since 1995 and Java has played a very important role in software development. Although there are many issues regarding its future due to events involving Oracle. Let us discuss these concerns and explore different viewpoints surrounding future of Java. We will explain whether Java is dying at the hands Oracle's influence or if it has the potential for a promising future. In this article at first, we will discuss about the challenges faced due by Oracle and the simplicity of coding in Java language. After that we will also discuss Java's ...
Read MoreHow to List All Tables in a Schema in Oracle Database?
Introduction In Oracle databases, a schema is a logical grouping of related objects, such as tables, views, and stored procedures. Each schema belongs to a specific database user and has a set of associated privileges. To list all tables in a schema in an Oracle database, you can use one of the views in the data dictionary. The `ALL_TABLES` view contains one row for each table in the current schema, while the `DBA_TABLES` view contains one row for each table in the entire database. To list the tables in a schema, you can use a SELECT statement to query the ...
