The lines of code in Kotlin that a developer needs to write are fewer compared to Java. This simply states that the developer can accomplish the assigned task in lesser time and effort with Kotlin. The codes can be easily read.

With the help of these features, the developer of Kotlin can easily make the identification of bugs and errors. Here are some of the characteristics of Kotlin-

1. Interoperability

Interoperability is an admirable feature of the Kotlin language. It doesn’t matter whether you have written a piece of code in Java or Kotlin; both will work together.

The help of the tool can be taken in Android Studio to transform the Java code into Kotlin.

2. Brilliant IDE and Support

JetBrains back Kotlin. Kotlin is inherited with extended support. The number of contributors compared to Java-like languages has surged. One can take the help of the growing community to fix the issues in the existing project.

3. Null Safety

Kotlin helps boost the safety of the applications, which helps remove the need to assign a variable or object. With this effect, the developers of Kotlin can boost their productivity while enabling the smooth functioning of the app.

Whereas Java used to consume a lot of time as Null Pointer Exception causes errors. The developers are assigned a null value to the variables and object reference.

4. Code Compilation Timing and Performance

With the help of Kotlin, the compilation of time and good performance can be achieved. The developer feels free to make use of Kotlin over choosing Java. Still, it has a long way to go in meeting the compilation speed of Java.

The compilation time of Java programs can be 10-15% faster. But when it comes to compiling programs incrementally, Kotlin does it better.

5. Functional Programming

Java supports functional programming while using the latest versions, whereas Kotlin contains procedural and functional programming compatibility.

It is helpful in facilitating access to some of the relevant features and functions like higher-order functions, inline functions, generics, recursion, anonymous functions, etc. All of these characteristics are essential for functional programming.

6. Checked Exceptions

A check exception or a logical expression determines the fact that something is wrong with the available code. At the time of the compilation process, it becomes easy to tackle things.

If a method carries that expression, the developers are assigned the “thrown” keyword. This helps save the time of developers to go through all the nonexistent exceptions and write the entire code.

7. Delegation

Kotlin can delegate an operation to the second delegate object, which is termed a helper object. Such objects are loaded with original content so that no developer needs not to mention the same again and again.

8. Data Classes

While working with big projects, the number of data classes is high, and their basic purpose is to hold the data. To accomplish a task with Java, one has to perform a lot of things like defining constructors, fields for data storage, etc.

In Kotlin, you can add the “data” keyword in the class definition to avoid manual setup.
