String pokedexno = a;

//type1.setIcon(new javax.swing.ImageIcon(getClass().getResource("C:/Program Files/Pokemon Online/Themes/Classic/types/type4.png")));
String trial1 = "";
Scanner x = null;
try{
x = new Scanner(new File("C:/Program Files/Pokemon Online/db/pokes/5G/type1.txt"));
}
catch(Exception e){
System.out.println("Could not find File - Error reading file : type1.txt");
}
while(x.hasNext()){
String trial = x.next();
String trial2 = x.next();
String pokedexno1 = pokedexno + ":0";
