How do you check if there is a vowel in Java?

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 vowels and consonants in Java string?

Algorithm

  1. Read an input string.
  2. Convert the string to lower case so that comparisons can be reduced.
  3. Iterate over it’s characters one by one.
  4. If current character matches with vowels (a, e, i, o, u ) then increment the vCount by 1.
  5. Else if any character lies between ‘a’ and ‘z’, then increment the count for cCount by 1.

How do you know how many vowels are in a string?

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 separate vowels and consonants in a string?

If there are more vowels than consonants, print first vowel first and recur for remaining string. If there are more consonants than vowels, print first consonant first and recur for remaining string. If counts are same, compare first vowel with first consonant and print the smaller one first.

How do you find a vowel in an array?

3 Answers

  1. You need to create a char array (e.g word[20]) for reading the string.
  2. You need to read line into the char array and not to int ( cin >> n; ).
  3. You cant read in a string using ‘cin’.
  4. you need to print sum (no. of vowels) outside loop.
