How do you check if a string contains a vowel?

You can read a character in a String using the charAt() method. To find the vowels in a given String you need to compare every character in it with the vowel letters.

How do you check that the input from the user is the vowel or not in Java using object oriented approach?

In Java, you use double quotes (” “) for strings and single quotes (‘ ‘) for characters. Now, to check whether ch is vowel or not, we check if ch is any of: (‘a’, ‘e’, ‘i’, ‘o’, ‘u’) . This is done using a simple if..else statement. We can also check for vowel or consonant using a switch statement in Java.

How do you count the number of vowels?

To count the number of vowels in a given sentence:

1. Read a sentence from the user.
2. Create a variable (count) initialize it with 0;
3. Compare each character in the sentence with the characters {‘a’, ‘e’, ‘i’, ‘o’, ‘u’ }
4. If a match occurs increment the count.
5. Finally print count.

How do you check if a string contains only digits?

Using Regular Expression:

1. Get the String.
2. Create a Regular Expression to check string contains only digits as mentioned below: regex = “[0-9]+”;
3. Match the given string with Regular Expression.
4. Return true if the string matches with the given regular expression, else return false.

How do you check if a string contains all vowels in C?

Check vowels occurence in a string

1. Input: First line contains N, the size of the string. Second line contains the letters (only lowercase).
2. Output: Print YES if all vowels are found in the string, NO otherwise.
3. Constraints: The size of the string will not be greater than 10,000. 1 ≤ N ≤ 10000.

How do you count the number of vowels and consonants in a string?

Algorithm

1. Define a string.
2. Convert the string to lower case so that comparisons can be reduced.
3. If any character in string matches with vowels (a, e, i, o, u ) then increment the vcount by 1.
4. If any character lies between ‘a’ and ‘z’ except vowels, then increment the count for ccount by 1.
5. Print both the counts.
