Scanner sc = new Scanner(System.in);
do
{
String guess;
int wL=0;
char hidden='r';
char gchar;
System.out.println("enter your word, stop to end.");
guess = sc.nextLine();
wL = guess.length();
while(guess != 'stop')
{
for(int i=0;i<wL;i++)
{
gchar=guess.charAt(i);
if(gchar = hidden)
{
System.out.println("Your guess does not contain the secret letter");
System.out.println("enter next word, stop to end.");
guess = sc.nextLine()
}
else
{
System.out.println("Your guess contains the secret letter");
System.out.println("enter next word, stop to end.");
