Checking If a Character is a Vowel in Java

Check if a Character is a Vowel in Java

In Java, checking if a character is a vowel can be done using either the switch statement or an if-else statement. Both methods are equally effective and provide accurate results. This tutorial will provide a brief overview of each method and the syntax used to implement it.

Using the Switch Statement

The switch statement allows you to check multiple conditions and execute different pieces of code depending on the condition. In this case, the switch statement is used to check the character argument passed in and see if it matches any of the vowels. The syntax for this statement is as follows:

char c = 'a';
switch (c) {
    case 'a':
    case 'e':
    case 'i':
    case 'o':
    case 'u':
        System.out.println("Vowel");
        break;
    default:
        System.out.println("Not a Vowel");
        break;
}

In this example, the character ‘a’ is evaluated against the cases in the switch statement. If the character matches any of the cases, the code within that block will be executed. The break statement is used to exit the switch statement after the code has been executed.

Using the If-Else Statement

The if-else statement is another way of achieving the same result as the switch statement. This statement works by evaluating a boolean expression and executing different pieces of code depending on the outcome of the expression. The syntax for this statement is as follows:

char c = 'a';
if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u') {
    System.out.println("Vowel");
}
else {
    System.out.println("Not a Vowel");
}

In this example, the character ‘a’ is evaluated against the boolean expression. If the expression evaluates to true, then the code within the if block will be executed. Otherwise, the code within the else block will be executed. This statement is more verbose than the switch statement but still achieves the same result.

In conclusion, both the switch statement and if-else statement can be used to check if a character is a vowel in Java. Using either statement correctly will yield accurate results.
