Get the random characters and print only the vowels in java.

Question

is it possible to get only vowels from the randomly generated characters in java? Help me with that please.

Answer 1

A randomly generated String, you mean ?
If yes:
String getVowels(str)
{
char[] vowels = {'a', 'e', 'i', 'o', 'u', 'y'};
String output = "";

for(int i = 0; i < str.length; i++)
{
for(int j = 0; j < vowels.length; j++)
{
if(str.charAt(i) == vowels[j])
{
output += str.charAt(i);
break;
}
}
}

return output;
}
