char ch;
int c = 0; // counter variable for consonants
int v = 0; // counter variable for vowels
System.out.println("Enter the 20 characters");
for (int i = 1; i <= 20; i++) i
{ch=in.next().charAt(0);
ch = Character.toUpperCase(ch);
if (Character.isLetter(ch)==true)
{if (ch == "A" || ch == "E" || ch == "T" || ch == "0" || ch == "U")
v++;
else
c++;
}}
System.out.println("Number of vowels = " + v);
