请大家帮帮忙

:Create a game in which let the user enter rock, paper or scissors, and  the computer randomly chooses rock, paper or scissors.  Then determine the winner.

Your games shall :
•Make sure the game works correctly whether the player enter a choice  in uppercase or lowercase letters or a combination of the two
•To allow for player misspellings, accept the player’s entry as long as the first two letters are correct. (In other words, if a player types “scixxrs”, you will accept it as “scissors”, because at least the first two letter are correct.
•When the player does not type at least the first two letters of the choice correctly, reprompt the player and continue to do so until the player’s entry contains at least the first two letters of one of the options
•Allow 10 complete rounds of the games. At the end, display counts of the number of times the player won, the number of times the computer won, and the number of tie games.
[Hints : Math.random() return a value of type double equal to 0.0 or less than 1.0 .  To find absolute value of num-guess, use the expression Math.abs(num-guess)]

不知道我做对吗，请大家改正我，如不对的话。

JAVA！！！这个嘛.....不懂
以前读书的时候看到这个就想到

好乱哦@@。还没学到package的code statement.

想知道自己做的对不对，最容易的方法就是自己 compile 来 run 看。
没有人会喜欢看那么一大堆 code 帮你 “检查答案” 的。
