I think most of you with Java Fundamentals if you want to learn more about Java check out my blog - Click Here. So some of the major features of Java include it is easy to learn and understand it’s designed to be platform-independent and secures it can work on a virtual machine as well and object-oriented Java relies heavily on the Java fundamentals. Java as of now that’s really your option for native applications. Android applications are developed using the language. So, if you know java you have better job opportunities that are the belief right but suppose nobody wants to just develop android applications all the time. Java does a whole lot more than just develop Andriod applications. It is an object-oriented programming language developed by Sun Microsystem which is now apparently owned by Oracle being such an old programming language. So let me give you a brief about this programming language. What is Java?Įvery Software Engineer out there could have worked with java for their project be it a fresher or be it an experienced person everybody out there would have worked on Java. Kotlin also introduces improved syntax as well as concise expression and abstractions. These methods can easily be generated by kotlin itself a central focus for kotlin is to enable mixed-language projects. It is an open-source statically typed language based on the java virtual machine a class that consumes more than 50 lines of code in java can actually be brought down to two to three lines in kotlin it can help you avoid all boilerplate code like you don't need to specify the getter and setters equals hash code and so on. Jet Brain a huge Company that created IntelliJ also created kotlin. So, the answer to this would be kotlin came into existence to improve the qualities of java and help in mobile development Then what about the fact that java has been around for 20 + years for now. So what is Kotlin? Kotlin is a simple programming language that is robust statically typed and less verbose than java, but this feature makes it the first choice for android development. So among these mobile development languages is the first and the foremost requirement of today’s world. It’s a well-known fact that every technology has something new to offer updates in the older version, introduction to newer technologies, and some that are not so new to us. Android was long in need of a modern language Kotlin filled the gap ever since it was announced as the official language for android development but definitely, java has a place to which is hard to complete. So to replace characters within a string, below is a better approach: public static void main(String args) Ĭhar chars = s.Despite the reputation of java as a very popular programming language. So essentially, "aeiou" would become "aaaaa" at the end since at the last character, you would have s = s.replace('u', 'a') which would replace every character with a. The problem with replacing every character of a string in a loop in this way is, on every next iteration, the replace would even replace any past characters if it matches the character.It would only replace if you assign it back to s as s = s.replace('a', 'e') s.replace('a', 'e') will not replace any character in the string since String object is immutable in Java.There are two issues with the way you are approaching.
