Discover the Power of Conditional Statements
When it comes to programming, conditional statements are essential tools that help us make decisions and execute specific actions based on certain conditions. In this article, we’ll explore two examples of how to check whether an alphabet is a vowel or consonant using if-else statements and when statements in Java and Kotlin.
The If-Else Statement Approach
Let’s start with a simple Java program that uses an if-else statement to determine whether a character is a vowel or consonant. The program stores the character ‘i’ in a char variable ch. To check if ch is a vowel, we use an if-else statement that evaluates whether ch is equal to any of the vowels (‘a’, ‘e’, ‘i’, ‘o’, ‘u’). If the condition is true, the program returns the string “vowel”; otherwise, it returns “consonant”.
The When Statement Advantage
In Kotlin, we can achieve the same result using a when statement, which is similar to a switch case in Java. However, unlike Java, the when statement is an expression that can return and store a value. This makes the code more concise and efficient. In our example, the when statement checks whether ch is equal to any of the vowels (‘a’, ‘e’, ‘i’, ‘o’, ‘u’). If it is, the program prints “vowel”; otherwise, it prints “consonant”.
A Closer Look at the Code
Let’s compare the equivalent Java code to the Kotlin example. In Java, we use a long if condition to check whether ch is a vowel or consonant. In contrast, the Kotlin when statement provides a more elegant solution that reduces the amount of code needed to achieve the same result.
Unlocking the Potential of Conditional Statements
By mastering conditional statements, you can write more efficient and effective code that makes decisions based on specific conditions. Whether you’re using if-else statements or when statements, the key is to understand how to apply these tools to solve real-world problems.
