What's wrong with my if-else statement? (Java)

I made this simple GUI program that counts the vowels and consonants of a
particular sequence of characters. The counter is okay, but I'm having a
problem with the if-else statement where I had to display a message when
that character is neither a vowel nor consonant... Here's the code:
//I initialized these variables:
public static int vowels = 0, consonants = 0, charac = 0;
public static String outputStr;
public static String conso = "bcdfghjklmnpqrstvwxyz";
public static String vow = "aeiou";
//Here's the code for my "count" button
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String userInput = jTextField1.getText();
userInput = userInput.toUpperCase();
conso = conso.toUpperCase();
vow = vow.toUpperCase();
String wordInput[] = userInput.split("");
vowels = 0;
consonants = 0;
charac = 0;
for(int i=0; i<wordInput.length; i++) {
for(int j=0; j<5; j++) {
char v = vow.charAt(j);
String VL = Character.toString(v);
if(VL.equals(wordInput[i])) {
vowels ++;
charac = 0;}
else {
charac += 1; }
}
for(int h=0; h<21; h++) {
char c = conso.charAt(h);
String CL = Character.toString(c);
if(CL.equals(wordInput[i])) {
consonants ++;
charac = 0; }
else {
charac += 1; }
}
}
String totalVow = Integer.toString(vowels);
String totalCons = Integer.toString(consonants);
jLabel5.setText(totalVow);
jLabel6.setText(totalCons);
//here's the if-else statement:
if (charac == 0) {
jLabel7.setText(" ");
}
else if (charac >= 1) {
jLabel7.setText("The sequence contains invalid characters.");
}
if (userInput.isEmpty()) {
jLabel7.setText("No input.");
}
}
Here's what it looks like:

I entered a "sequence" of characters that does not have any special
characters or digits. But it still displays the message wherein it has
other characters other than the vowels and consonants. Is there something
wrong with the if-else statement? Thanks for the help :)
