How Kotlin Makes Coding Easy For Android Developers?

Kotlin is now an officially supported language in Android which is developed by JetBrains. It’s expressive and powerful. It is like a boon for the Android developers.

Reasons why we have to use Kotlin instead of java

• Kotlin is multi-platform
  • With Kotlin you can do Android development, front End, server development, and can also write Gradle script.
• Java developers can understand most of the codes without ever having written a line of Kotlin,  So Java developers can easily accept Kotlin.
• It’s much safer than java
  • It’s an easily removable nullpointerException.
  • Kotlin contains less code than java hence chances for code failure are very less, and therefore it becomes more stable.
  • Kotlin code is easier to understand when someone else reads it and, again, it’s more difficult to introduce errors.

• Advantage of Kotlin
  • It helps developers to make their app developing process faster. In Kotlin 20% less coding is needed compared to Java.
  • It is a very simple language as compared to Java and easy for freshers to learn and use. It is accessible with an intuitive syntax that enables developers to learn quickly.
  • The best advantage of Kotlin is you can add Kotlin class in your project even if your project is developed in java.
  • All the libraries that are working for the Android project are supported by Kotlin so don’t worry to use third party libraries in your Kotlin project.
  • It enables the developers to use the Java frameworks in their new Kotlin projects by using latest frameworks without the need of changing the whole project in Java.
  • Kotlin supports open developer networks and the depth of open source makes the network strong which however is not restricted to any single company.
  • Kotlin Android programming language App development has been made available for free. You don’t need to worry about the costing or charges here.
    • Kotlin provide smart type casting
      
    • It’s easy to remove nullpointerexception in Kotlin
      Ex:here? sign check that object is null or not. if it is null than compiler does not allow to run that particular sequence.
    • In Kotlin we can assign functions default value as a parameter
      Ex:
    • Most useful things of Kotlin is lambda expressions.

• Use of Lambda  in Kotlin
  • What is lambda?
    • Lambda is a way of representing a function in Kotlin
    • Ex. for how to define setOnClickListener in Lambda expression.
  • Here we define some of the most useful lambda functions in development so you can easily use that functions and reduce your line of code for better App performance.
    • filter()
      • Filter return the element which satisfies your defined condition
        Ex.
      • Here it is autogenerated parameter which we don’t specify.
    • map()
      • Map applies your condition in all elements of your collection
        Ex.
      • You can use both filter() and map() function together
        Ex.
    • all()
      • All functions check that, are all the elements of collection satisfying a condition
        Ex.
    • any()
      • Any function is working like or condition in java. It returns true if only one element satisfies the condition.
        Ex.
    • count()
      • Find return first element which satisfies your condition
        Ex.
    • find()
      • Find return first element which satisfies your condition
        Ex.
