$/$ Write a for loop that counts from $0$ to the length$-1$ of the string variable sentence $($see above$)$

$//$ Inside the loop use the charAt$()$ method of the String class and check if the current character of the sentence is a

$//$ one of $\text{'}$a$\text{'}\text{'}$e$\text{'}\text{'}$i$\text{'}\text{'}$o$\text{'}\text{'}$u$\text{'}.$

$//$ If it is$,$ increment the appropriate count variable by $1$

$//$ Hints: use sentence.length$()$ to determine the length of the sentence string. Use sentence.charAt$($i$)$ to get the ith character in the string.

$//$ Keep in mind that the char variable type is a primitive type $-$ it is not a string!. So compare a char variable to constant characters like $\text{'}$e$\text{'}$ not $"$e$"$
