我在编程方面不太好。有人帮我查看我的代码吗?我总是得到错误 "线程中的异常" main" java.lang.ArrayIndexOutOfBoundsException:-1"
以下是我的代码:
import java.util.Random;
public class Knight
{
Random rand=new Random();
public void start()
{
int[][] square = new int[8][8];
int currentRow;
int currentColumn;
int x,y,count,tempy,tempx,lowest=0,count1=0;
int moveNumber;
int [] horizontal={2,1,-1,-2,-2,-1,1,2};
int [] vertical={-1,-2,-2,-1,1,2,2,1};
int access[ ][ ] = { { 2, 3, 4, 4, 4, 4, 3, 2 },
{ 3, 4, 6, 6, 6, 6, 4, 3 },
{ 4, 6, 8, 8, 8, 8, 6, 4 },
{ 4, 6, 8, 8, 8, 8, 6, 4 },
{ 4, 6, 8, 8, 8, 8, 6, 4 },
{ 4, 6, 8, 8, 8, 8, 6, 4 },
{ 3, 4, 6, 6, 6, 6, 4, 3 },
{ 2, 3, 4, 4, 4, 4, 3, 2 } };
for(x=0;x<8;x++)
{
for(y=0;y<8;y++)
{
square[x][y]=0;
}
}
currentRow=rand.nextInt(7);
currentColumn=rand.nextInt(7);
tempx=currentRow;
tempy=currentColumn;
square[currentRow][currentColumn]=1;
for(count=2;count<=64;count++)
{
for(moveNumber=0;moveNumber<8;moveNumber++)
{
tempx+=vertical[moveNumber];
tempy+=horizontal[moveNumber];
if(tempy >= 0 && tempy < 8 && tempx >= 0 && tempx < 8 && square[tempx][tempy]==0 && square[tempx][tempy]==0)
{
if(access[tempx][tempy]<access[currentRow][currentColumn])
{
lowest=moveNumber;
tempx-=vertical[moveNumber];
tempy-=horizontal[moveNumber];
}
}
else
{
tempx-=vertical[moveNumber];
tempy-=horizontal[moveNumber];
}
}
currentRow+=vertical[lowest];
currentColumn+=horizontal[lowest];
tempx=currentRow;
tempy=currentColumn;
square[currentRow][currentColumn]=count;
count1++;
}
System.out.printf("The tour ended with %d moves\n \t0\t1\t2\t3\t4\t5\t6\t7\n",count1+1);
for(x=0;x<8;x++)
{
System.out.printf("%d\t", x);
for(y=0;y<8;y++)
{
System.out.printf("%d\t",square[x][y]);
}
System.out.println();
}
}
}
public class KnightTesta
{
public static void main(String[] args)
{
Knight test=new Knight();
test.start();
}
}
请帮助我修改代码,因为我也能做到正确。如果我没有启发式解决方案,我可以正确地获取代码(意味着我无法完成64个游览)。
谢谢,非常感谢,希望你们能够理解我的代码,因为我不擅长编程T ^ T.
