/** * This program lets the user play one or more guessing games. In each game, the * computer selects a number in the range 1 to 100. The use tries to guess the * numbers. If the user's guess is right, the user wins the game. If the user * makes six incorrect guesses, the user loses the game. The computer tells the * user whether his guess is high or low. After each game, the computer askes * the user whether the user wants to play again. At the end, the program * reports the number of games that were won by the user. */ public class GuessingGame2 { static int gamesWon; // The number of games won by // the user. public static void main(String[] args) { gamesWon = 0; // This is actually redundant, since 0 is // the default initial value.

look this can be done by rand(100) but the only problem you will have is that it returns random value between 0 to n, 0 included , where n is the argument given so you can write internal code for that int rand(100) { if(rand(100)==0) rand(100); } in the meanwhile you will increase the number of attempts like guess++; //thats it , try it yourself
