Java is a high-level, object-oriented programming language that was developed by James Gosling at Sun Microsystems in the mid-1990s. It is a general-purpose language that is widely used for developing desktop, web, and mobile applications, as well as for building enterprise-level software solutions. One of the main features of Java is its platform independence, which means that Java code can be written once and run on any platform that supports Java, without the need for recompilation. This is made possible by the Java Virtual Machine (JVM), which interprets Java bytecode and executes it on different platforms. Java is known for ... Read More

Java and C are two popular programming languages with different features, syntax & applications. For the first time, Java was introduced by Sun Microsystems in 1995 & operates on the Java Virtual Machine (JVM). C is a procedural programming language produced by Dennis Ritchie at Bell Labs in 1972. Both Java and C have their pros and cons. But here, we will explore how Java is better than C. Memory Management One of the notable distinctions between Java and C is in memory management. C uses manual memory management, which requires the programmer to allocate & deallocate memory explicitly. This ... Read More

In jQuery, we can trigger the ‘mousemove’ event to detect the mouse pointer's location on the web page. Also, we can detect the scroll using the ‘scroll’ event and subtract that value from the y position to get the relative mouse location. Using the ‘overflow-y: scroll’ CSS property, we can make any div scrollable. Syntax Users can follow the syntax below to get the relative mouse position while scrolling on the div. $('#main').scroll(function (event) { if (finalScroll != $('#main').scrollTop()) { location_y -= finalScroll; finalScroll = ...

In JavaScript, an object contains the properties in the key-value format. We can access any property of an object using the property name by taking the object as a reference. Sometimes, we try to access the object property that doesn’t exist in the object. In such cases, we get the undefined value. Let’s understand it by the example below. Example (Accessing the Object Properties) In the example below, we have created the object and added some properties. Also, we have added some nested properties. After that, we try to access the ‘prop5’ property which is a nested property of the ... Read More
The code often throws an error, and handling errors is more important. JavaScript also allows users to throw a custom error using the ‘throw’ keyword. We can catch the errors in the catch block. We can use the try-catch syntax to catch errors thrown by normal functions. Let’s understand it by the example below. Example 1 (Throw Errors in Regular Function) In the example below, we have created the throwError() regular function, which uses the throw keyword to throw an error with the custom error message. We have executed the function inside the try block. If the function throws any ... Read More
