It looks like the Scanner is being used correctly here and being assigned to a variable correctly but I Cannot figure out what is going on. When I play this game in the code, the INT gets pulled in just fine. The strings will not get pulled in for some reason and even if I hardcode "yes" for the string it still exits the code.
package testTraining;

public class GuessingGame {
static int gamesPlayed; // The number of games played.
static int gamesWon; // The number of games won.
public static void main(String[] args) {
gamesPlayed = 0;
gamesWon = 0; // This is actually redundant, since 0 is
// the default initial value.
System.out.println("Let's play a game. I'll pick a number between");
System.out.println("1 and 100, and you try to guess it.");
String yesno = "yes";
Scanner yesScan = new Scanner(System.in);
do {
playGame(); // call subroutine to play one game
System.out.print("Would you like to play again? ");
yesno = yesScan.next();
} while (yesno == "yes");
System.out.println();
System.out.println("You played " + gamesPlayed + " games,");
System.out.println("and you won " + gamesWon + " of those games.");
System.out.println("Thanks for playing. Goodbye.");

computersNumber = (int)(100 * Math.random()) + 1;
// The value assigned to computersNumber is a randomly
// chosen integer between 1 and 100, inclusive.
