Java vs Kotlin: Syntax Comparison and Overview

7. Java vs Kotlin Syntax Java final int x; final int y = 1; int w; int z = 2; z = 3; w = 1; Kotlin val x: Int val y = 1 var w: Int var z = 2 z = 3 w = 1 https://fabiomsr.github.io/from-java-to-kotlin/

8. Bits Operations Java final intandResult = a & b; final intorResult = a | b; final intxorResult = a ^ b; final intrightShift = a >> 2; final intleftShift = a << 2; Kotlin valandResult = a and b valorResult = a or b valxorResult = a xor b valrightShift = a shr 2 valleftShift = a shl 2 Is As In Java if(x instanceof Integer){ } final String text = (String) other; if(x >= 0 && x <= 10 ){} Kotlin if (x is Int) { } val text = other as String if (x in 0..10) { }

17. Null Safety Kotlin val name: String? = null varlastName: String? lastName = null varfirstName: String firstName = null // Compilation error!! Java final String name = null; String lastName; lastName = null val length = b!!.length
