紧急！！！用java做一个小游戏有窗口的。。

将以下代码保存为MainFrame.java JDK1.6编译通过
保存我没有做，也不难。方法我已经空下了，你可以自己写写试试.
把txtGuessRecord.getText()的内容写到文件里就行了

java: 怎样算行列？
一行一行循环的读取文件里面的内容，定义变量int row=0;作为行标计数器，每一行数据读取出来是一个String（定义 String lineStr;）然后通过lineStr.charAt(i)循环读取每一个字符，如果lineStr.charAt(i)是字符'x'则记录下此时的row和i，最后就能指出所有'x'的位置
java 生成0-80之间10个不同的随机数
那就加个判断吧
public class Test1
{
public static void main(String[] args) {
int[] i=new int[10];
int j=1;
i[0]=(int)(Math.random()*81);
while(ji.length){
i[j]=(int)(Math.random()*81);
boolean b=true;
for(int k=0;kj;k++){
if(i[j]==i[k]){
b=false;
}
}
if(b==true)
j++;
}
for(int x=0;xi.length;x++)
System.out.println(i[x]);
}
}
这样可以了
怎么用Java 二维数组编写一个7*7的矩阵方格
import java.util.Scanner;
public class Main1 {
public static void main(String ars[]){
Scanner s=new Scanner(System.in);
System.out.println("请输入数组行数和列数");
int x=s.nextInt();
int y=s.nextInt();
int [][]awarry=new int[x][y];//初始化数组
System.out.println("请输入数组元素");
for(int i=0;ix;i++)//循环输入
for(int j=0;jy;j++)
awarry[i][j]=s.nextInt();
System.out.println("你输入的数组为");
for(int i=0;ix;i++){//循环输出
for(int j=0;jy;j++)
System.out.print(awarry[i][j]+"\t");
System.out.println();
}
}
}
运行示例：
请输入数组行数和列数
7 7
请输入数组元素
|——|——
你输入的数组为
