Java Program to find total Vowel, Consonant, and words in a String
There are five vowels (a, e, I, o, u) in the English language and rest are consonants
among 26 letters of the English alphabet.
In the following program, the total vowels, total consonants, and total
words are calculated. We have built the program in the following steps.
Step 1: String st taken
Step 2: Calculate the length of the String
Step 3: Start a for loop and execute till its length one by one
Step 4: Pick one character at a time with ch = st.charAt(i); and pass
to switch(ch)
Step 5: check with the case the vowels and count counters of each vowel
variable if find
Step 6: After then calculate the consonants with the formula
Consonants =
length of String - (total vowels + space)
Step 7: Print individual vowels, consonants, and total words.
public class StringEx1
{
public static void
main(String args[])
{
String st="Education
is must for all";
char ch;
int i, l, c=0,sp=0,
con,v1, v2, v3, v4, v5;
v1 = v2 = v3 = v4 = v5
=0;
l=st.length();
for(i=0;i<l;i++)
{
ch=st.charAt(i);
switch(ch)
{
case 'A':
case 'a':
v1++; // vowel a count
break;
case 'E':
case 'e':
v2++; // vowel e count
break;
case 'I':
case 'i':
v3++; // vowel i count
break;
case 'O':
case 'o':
v4++; // vowel o count
break;
case 'U':
case 'u':
v5++; //
vowel u count
break;
}
// Calculate total
Space for count words
if(ch==' ')
sp++;
}
// consonents = length of String - (total vowels + space)
con = l - (v1 + v2 + v3 +
v4 + v5 + sp);
System.out.println("Total String Length = " + l);
System.out.println("Total Vowel A= " +v1);
System.out.println("Total Vowel E= " +v2);
System.out.println("Total
Vowel I= " +v3);
System.out.println("Total Vowel O= " +v4);
System.out.println("Total Vowel U= " +v5);
System.out.println("Total Words = " +(sp+1)); // total space
plus 1
System.out.println("Total Consonants = "+ con); }
}
Output
Total String Length = 25
Total Vowel A= 2
Total Vowel E= 1
Total Vowel I= 2
Total Vowel O= 2
Total Vowel U= 2
Total Words = 5
Total Consonants = 12
