Answer 1

Do you mean variables/indexes in a string array? or number of characters in a string variable?

Answer 2

do you mean length of string??

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
String str=sc.nextLine();
System.out.printf("Length is %s",str.length());
}
}

Answer 3

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
int Vcount=0;
int ConCount=0;
System.out.println("enter string");
String str=sc.nextLine();
for(int i=0;i<str.length();i++){
if(str.charAt(i)=='a'|| str.charAt(i)=='e'||
str.charAt(i)=='i'||str.charAt(i)=='o'||str.charAt(i)=='u'){

Vcount++;

}

else {
ConCount++;
}
}

System.out.println("vowels are "+Vcount);

System.out.println("Coms are "+ConCount);

System.out.println("code by ManikanthVanka");
}
}

Answer 4

number of vowels ina string variable

Answer 5

Looking for the code or some guidance?

Answer 6

looking for code

Answer 7

you can also get this program from code ground in sololearn.

Answer 8

for(int i = 0; i < str.length(); i++)
if(str.charAt(i) == 'a')
numVowels++;
Use an if in the for loop for each vowel or use the same if by using the OR operator ||. Very quick and easy.
