Pig Latin converter

So I made this pig latin translator in class today. It doesn't handle capitalization or punctuation, but it can handle multiple words at once, separated by spaces.

import javax.swing.JOptionPane;

public class home {

static String[] vowels = {"a", "e", "i", "o", "u", "y"};

public static void main(String[] args) {

String input;

String out;

boolean x = true;

while (x) {

input = JOptionPane.showInputDialog("Words to change?");

if (input.equals("stop")){

x=false;

break;

}

out = "";

for (String ret: input.split(" ")){

int vpos = find(ret);

System.out.println(vpos);

if (vpos > 0) {

out = out + ret.substring(vpos) + ret.substring(0, vpos) + "ay ";

} else {

out = out + ret + "way ";

}

}

JOptionPane.showMessageDialog(null, out);

}

}

public static int find(String inp) {

int pos = -1;

for (String vwl: vowels) {

int vpos = inp.indexOf(vwl);

if ((vpos >= 0) && ((vpos < pos)||(pos==-1)) && (vpos != inp.indexOf("qu")+1)) {

pos=inp.indexOf(vwl);

}

}

return pos;

}

}
