Introduction The continue statement in Kotlin is used to skip the current iteration of the nearest enclosing loop and proceed to the next iteration. This is useful when you want to skip certain iterations based on a specific condition. This chapter will cover the syntax and usage of the continue statement in Kotlin with examples. …
Introduction The break statement in Kotlin is used to terminate the nearest enclosing loop immediately, regardless of the loop condition. This is useful when you want to exit a loop based on a specific condition before the loop would naturally terminate. This chapter will cover the syntax and usage of the break statement in Kotlin …
Introduction The do-while loop in Kotlin is used to repeatedly execute a block of code as long as a specified condition is true. Unlike the while loop, the do-while loop guarantees that the loop body will be executed at least once because the condition is evaluated after the loop body. This chapter will cover the …
Introduction The while loop in Kotlin is used to repeatedly execute a block of code as long as a specified condition is true. It is a fundamental control flow statement that allows for repeated execution of a block of code based on a condition. This chapter will cover the syntax and usage of the while …
Introduction The for loop in Kotlin is used to iterate over a range, array, or collection of elements. It is a fundamental control flow statement that allows you to execute a block of code multiple times. This chapter will cover the syntax and usage of the for loop in Kotlin with examples. Basic for Loop …
Introduction The when statement in Kotlin is a powerful control flow statement that allows you to choose between multiple possible execution paths based on the value of an expression. It is similar to the switch statement found in other programming languages, but more expressive and versatile. This chapter will cover the syntax and usage of …
Introduction The if statement is a fundamental control flow statement in Kotlin that allows you to execute a block of code based on a specified condition. This chapter will cover the syntax and usage of the if statement, if-else statement, and if-else if-else statement with detailed explanations and examples. 1. if Statement The if statement …
Introduction Control flow statements in Kotlin allow you to direct the order of execution of statements in your program. These statements are essential for making decisions, looping through code, and managing the flow of your application. This chapter will cover the different types of control flow statements available in Kotlin, along with examples and their …
Introduction Bitwise operators in Kotlin are used to perform bit-level operations on integer types. These operators are essential for tasks that require direct manipulation of individual bits within an integer. This chapter will cover the different types of bitwise operators available in Kotlin, along with examples and their syntax. Types of Bitwise Operators 1. and …
Introduction Logical operators in Kotlin are used to combine multiple Boolean expressions or to invert a Boolean value. These operators are essential for making decisions in your code based on multiple conditions. This chapter will cover the different types of logical operators available in Kotlin, along with examples and their syntax. Types of Logical Operators …
Introduction Assignment operators in Kotlin are used to assign values to variables. They provide a way to modify the value of a variable using various operations. Understanding assignment operators is essential for writing efficient and concise code. This chapter will cover the different types of assignment operators available in Kotlin, along with examples and their …
Introduction Relational operators in Kotlin are used to compare two values. They return a Boolean result (true or false) based on the comparison. These operators are essential for making decisions in your code by evaluating conditions. Types of Relational Operators 1. == (Equal to) Checks if two values are equal. Syntax: val result = operand1 …
Introduction Arithmetic operators in Kotlin are used to perform basic mathematical operations such as addition, subtraction, multiplication, division, and modulus. These operators are essential for performing calculations in your programs. This chapter will cover the different types of arithmetic operators available in Kotlin, along with examples and their syntax. Types of Arithmetic Operators 1. + …
Introduction Operators are special symbols that perform operations on variables and values. In Kotlin, operators are used for arithmetic calculations, comparisons, logical operations, and more. This chapter will cover the various types of operators available in Kotlin, along with examples and their syntax. Types of Operators 1. Arithmetic Operators Arithmetic operators are used to perform …
Introduction Type conversion is the process of converting a value from one data type to another. In Kotlin, type conversion is necessary when you want to perform operations on values of different types. Unlike some programming languages, Kotlin does not perform implicit type conversions. Instead, you must explicitly convert types using built-in functions. This chapter …
Introduction Understanding data types is fundamental to effective programming. In Kotlin, data types specify the kind of values that variables can hold. Kotlin is a statically-typed language, which means that the type of a variable is known at compile time. This chapter will cover the basic data types in Kotlin, including examples and syntax for …
