In Kotlin 20% less coding is needed compared to Java.<\/li>\n<li>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.<\/li>\n<li>The best advantage of Kotlin is you can add Kotlin class in your project even if your project is developed in java.<\/li>\n<li>All the libraries that are working for\u00a0the Android project are supported by Kotlin so don\u2019t worry to use third party libraries in your Kotlin project.<\/li>\n<li>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.<\/li>\n<li>Kotlin supports open developer networks and the depth of open source makes the network strong which however is not restricted to any single company.<\/li>\n<li>Kotlin Android programming language App development has been made available for free. You don\u2019t need to worry about the costing or charges here.\n<ul>\n<li>Kotlin provide smart type casting<br \/>\n<a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/11.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3025\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/11.jpg\" alt=\"1\" width=\"800\" height=\"113\" \/><\/a><\/li>\n<li>It\u2019s easy to remove nullpointerexception in Kotlin<br \/>\n<strong>Ex:<\/strong><a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/21.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3026\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/21.jpg\" alt=\"2\" width=\"800\" height=\"113\" \/><\/a><span style=\"font-weight: 400\">here? sign check that object is null or not. if it is null than compiler does not allow to run that particular sequence.<\/span><\/li>\n<li>In Kotlin we can assign functions default value as a parameter<br \/>\n<strong>Ex:<\/strong><a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/31.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3027\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/31.jpg\" alt=\"3\" width=\"800\" height=\"113\" \/><\/a><\/li>\n<li>Most useful things of Kotlin is lambda expressions.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li><strong>Use of Lambda\u00a0 in Kotlin<\/strong>\n<ul>\n<li><span style=\"font-weight: 400\">What is lambda?<\/span>\n<ul>\n<li>Lambda is a way of representing a function in Kotlin<\/li>\n<li>Ex. for how to define setOnClickListener in Lambda expression.<a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/41.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3028\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/41.jpg\" alt=\"4\" width=\"800\" height=\"170\" \/><\/a><\/li>\n<\/ul>\n<\/li>\n<li>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.\n<ul>\n<li><strong>filter()<\/strong>\n<ul>\n<li>Filter return the element which satisfies your defined condition<br \/>\n<strong>Ex.<\/strong><a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/51.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3029\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/51.jpg\" alt=\"5\" width=\"800\" height=\"100\" \/><\/a><\/li>\n<li>Here it is autogenerated parameter which we don\u2019t specify.<\/li>\n<\/ul>\n<\/li>\n<li><strong>map()<\/strong>\n<ul>\n<li>Map applies your condition in all elements of your collection<br \/>\n<strong>Ex.<\/strong><a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/6.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3030\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/6.jpg\" alt=\"6\" width=\"800\" height=\"100\" \/><\/a><\/li>\n<li>You can use both filter() and map() function together<br \/>\nEx.<a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/7.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3031\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/7.jpg\" alt=\"7\" width=\"800\" height=\"100\" \/><\/a><\/li>\n<\/ul>\n<\/li>\n<li><strong>all()<\/strong>\n<ul>\n<li>All functions check that, are all the elements of collection satisfying a condition<br \/>\nEx.<a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/8.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3032\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2018\/05\/8.jpg\" alt=\"8\" width=\"800\" height=\"140\" \/><\/a><\/li>\n<\/ul>\n<\/li>\n<li><strong>any()<\/strong>\n<ul>\n<li>Any function is working like or condition in java.
