plz explain what is wrong in this program with the solution

Answer 1

The mistake is : WHAT IS A,E,I,O,U??? You have to write them as 'a' 'e' 'i' 'o' 'u' , See your mistake below↓
Better to write the statement
case a:s="VOWEL"; 
break;
And such other statements in the program as
Corrected statement
case 'a':
S.....O......println(vowel)
And at last if the letter which the user entered is not a vowel ,it will print in this way
"the letter you have entered is b" It will not specify whether it is a consonant or vowel...
