Reading Time: 3 minutes Error handling is the process of handling the possibility of failure. For example, failing to read a file and then continuing to use that bad input would clearly be problematic. Noticing and explicitly managing these errors saves the rest of the program from various pitfalls. When an exception occurs, say an Arithmetic Exception then the current operation is aborted. Then the runtime system looks for an exception Continue Reading
Reading Time: 3 minutes In the previous blog ZIO Effects: How to Handle Errors? we have learned about How ZIO provides various means to handle and respond to failures. In addition to this blog, we will see all the ways to handle the exceptions with its Implementation. Either If the effect fails, the result is in the form of Left If the effect succeeds, the result is in the form Continue Reading
Reading Time: 4 minutes Introduction: One of the fundamental and important aspects of programming is Exception Handling. A program needs an environment to handle the potential errors and abnormal conditions. Programming does not end with writing code that executes and creates a result, as we also have to handle errors in a user-friendly manner. There are several types of errors that could occur when we run a program. Some Continue Reading
Reading Time: 4 minutes Pattern Matching: Scala Pattern matching is one of the features of functional programming that make it such an awesome paradigm. This tool is somewhat similar to switch statements you might be familiar with from other languages such as Java or Python, however Scala pattern matching is a much more powerful tool. In short, pattern matching allows one to check a value against a pattern as Continue Reading
Reading Time: 6 minutes Exception handling is very important whenever we are developing any application. In this blog I will cover the magic of exception handling in Scala.
Reading Time: 8 minutes Hello all, in this blog post we will study one of the strongest features of the Java language, enum’s. A good understanding of Java enum can make your program stand out of the crowd, and we will see how. We’ll establish a good understanding of the feature, learn how Java enum are different from other languages. Also, we will see the scenarios where we can Continue Reading
Reading Time: 3 minutes Hi Folks! As part of this blog, we will explore how we can handle exception in the different computing stages when we use CompletableFuture. We assume the read has the basic idea of the CompletableFuture. Nonethless, will start with the basic introduction of the CompletableFuture. What is CompletableFuture A CompletableFuture is used for asynchronous programming which was introduced as an improvement of the java Future API in Continue Reading
Reading Time: 2 minutes Error Propagation means the code, that detects the problem, must propagate error information back to the caller function so that it can handle the problem. In the real world, the practice of Error Propagation is necessary. One of the benefits is that your code will look cleaner by simply propagating error information back to the caller that can handle the error and another benefit is Continue Reading
Reading Time: 3 minutes If you are coming from Java background, where you have used Exception Handling extensively and you have started working on new language like RUST, which doesn’t support Exception Handling then you will be forced to think that does such kind of world really exists? The Java story Java provides full coverage to Exceptions and those are required to be handled with try-catch like construct. In Java, Continue Reading
Reading Time: 2 minutes In our previous blog Exception Handling – #2, we talked about how we can handle exception using Either. In this blog, we will explore further about Either, how we can elegantly handle exceptions using Either while working with Collections. We use collections when we want to perform some operations on elements. But what if something goes wrong while performing the transformation, do you have any Continue Reading
Reading Time: 3 minutes In our previous blog, we have seen how we can handle exceptions using try/catch and Try block. In this blog, we will explore how we can handle exceptions using Either. Either, just like a Try, is also a container type which can have one value either Left or Right at a time. We can also use Option to handle exceptions but if an exception occurs returning Continue Reading
Reading Time: 3 minutes While building an application, it is common that something might go wrong. What if there is an attempt to divide a number by 0 or fetching the data from the database which does not exist, or reading a file which can’t be located? We need to handle such situations to make sure our application does not go down. Every language provides ways to handle such Continue Reading
Reading Time: 2 minutes Try with resources is a special type of try statement where we can declare more than one resources within a single try statement. This feature came in Java 7. But it has some limitation with itself that overcomes in Java 9. https://gist.github.com/er-rishi/db16acf92d89a973111ff22e36b7cb4b We will discuss this limitation through the examples. Now, Firstly we have to know what is resource actually, A resource is an object that must be closed Continue Reading
