[Solved] Switch case Java error in coding [closed]

by 


char eng = jTextField1.getText().charAt(0);  //if you method return a String it gets the 1st character
switch(eng){
   case'a':
   case'e':
   case'i':
   case'o': 
   case'u': jTextField2.setText("It is a vowel");
            break;
   default: jTextField2.setText("It is not a vowel");
            break;
 }

But better way : 

char eng=jTextField1.getText().charAt(0);
ArrayList<Character> list=new ArrayList<Character>();
list.add('a');
list.add('e');
list.add('i');
list.add('o');
list.add('u');
list.add('y');
if(list.contains(eng)){
    jTextField2.setText("It is a vowel");
}else{
    jTextField2.setText("It is not a vowel");
}
