Guessing number games (Java)

Game rules:

         Usually played by two people, one side out of numbers, the other guessing. The number of people to think of a good one without repeating the number of 4 digits, can not let the guessing people know. Guess the person can start to guess. Each guess a number, the number of people to give a few a a few B according to this figure, where a before the number indicates that the number of correct position is also the number of correct numbers, and B before the number of the number is correct and the number of wrong position.         If the correct answer is 5234, and guess the person guess 5346, then is 1A2B, which has a 5 of the position of the pair, recorded as 1 A, and 3 and 4 of the two number pairs, and the position is not correct, so the record is 2B, together is 1a2b.

Run.java:

Package Xjj.java.guessnumber2;public class Run {public static void main (string[] args) {jguessgame g=new jguessgame (); g.s Tr=guessnumb.getnumber ();//Get a random four-digit number}}

Guessnumb.java:

Package Xjj.java.guessnumber2;public class Guessnumb {public static String GetNumber () {//randomly generates four-digit  char[] Ch=new Char [4];for (int i=0;i<ch.length;i++) {ch[i]= (char) ((int) (Math.random () *10) + ' 0 ');} SYSTEM.OUT.PRINTLN (CH); String Str=new string (ch); System.out.println (str); return str;}}

The first use of Java to do graphical interface, there are many deficiencies, let me slowly improve ha!
