In Kotlin, "toString()" method works on nullable types. Method signature, "public fun Any?.toString(): String" From Kotlin Docs, Returns a string representation of the object. Can be called with a null receiver, in which case it returns the string "null". If we want to replace the "null" string to empty string, we can use "nullable?.toString().orEmpty()" Note: Using the null safety (?) operator is required to ensure it is not converted to "null" string. To make this change throughout the project, We can use an extension function as shown below. #kotlin #android #androiddevelopment #androiddev #kotlindeveloper

How to use synchronized in Kotlin? To use synchronized in Kotlin, you can apply it to a block of code using the synchronized keyword followed by the object you want to synchronize on. The synchronized block ensures that only one thread can access the block at a time, providing thread-safety for the shared resource. Here's an example of using synchronized in Kotlin: In this example, the Counter class maintains a private count variable. The increment() and getCount() methods are synchronized using the synchronized keyword followed by the this reference, which refers to the instance of the Counter class. Two threads are created that concurrently increment the counter using the increment() method. By applying synchronization to the critical sections of the code, we ensure that only one thread can access the block at a time, preventing race conditions and maintaining the correctness of the count. Finally, the getCount() method is also synchronized to safely retrieve the final count value. #kotlin #kotlindeveloper #android #selfawarenessjourney

Operator overloading in Kotlin 🚀 Operator overloading in Kotlin allows you to define custom behaviors for built-in operators, such as "+", "-", "*", and others, when applied to instances of your own classes. Consider a class Point with x and y coordinates and you have to add two Points. By default, Kotlin doesn't know how to add two Point objects together using the "+" operator. With `operator overloading`, you can define a specific function within the Point class to handle the `addition` operation. For example, you can create a function, mark it with `operator` modifier and name it `plus`(predefined) operator fun plus(point: Point): Point which takes another `Point object as a parameter` and `returns a new Point object` with the sum of their coordinates. When you use the "+" operator between two Point objects, Kotlin will recognize that you've defined a custom behavior for the "+" operator in the Point class and use that function to perform the addition. #kotlin #kotlinandroid #android #androiddevelopment #operators
