Operators in Kotlin
Kotlin, like many programming languages, uses operators to perform various operations on values. Here's a breakdown of the common operator categories in Kotlin:
1. Arithmetic Operators:
+: Addition-: Subtraction*: Multiplication/: Division%: Remainder (modulo)
2. Assignment Operators:
=: Assignment+=: Addition assignment (e.g.,x += 5is equivalent tox = x + 5)-=: Subtraction assignment*=: Multiplication assignment/=: Division assignment%=: Remainder assignment
3. Comparison Operators:
==: Equal to!=: Not equal to>: Greater than<: Less than>=: Greater than or equal to<=: Less than or equal to
4. Logical Operators:
&&: Logical AND||: Logical OR!: Logical NOT
5. Unary Operators:
+: Unary plus-: Unary minus++: Increment--: Decrement!: Logical NOT
6. Equality Operators:
==: Structural equality (checks if values are equal)===: Referential equality (checks if references point to the same object)!=: structural inequality!==: referential inequality
Key Kotlin Features Regarding Operators:
- Operator Overloading: Kotlin allows you to overload operators, meaning you can define how operators work for your custom classes. This provides a way to make your code more expressive.
- "==" vs. "===": It's important to distinguish between
==and===.==checks for structural equality (the values are the same), while===checks for referential equality (they are the same object in memory).
To get the most accurate and in depth information, I recommend checking the official kotlin documentation.
