澄清一下,这是一项家庭作业.我只是在寻找建议,我不是在寻找别人为我做功课.
我上半场已经完成了.它使用两个数组来打印Asterisk设计(在这种情况下,字母’S’.工作正常.然后,我跳过两行并打印设计但翻转(所以每行反转).它似乎工作正常,但是当我运行该程序时,它打印出两个S,而第二个没有反转.任何关于我做错的想法?
public class Design {
public static void main (String [] args) {
char [] array = new char [150];
for (int index = 0; index < array.length; index ++)
{
array [index] = '#';
}
int [] indexNumbers = {
0,1,2,3,4,5,6,7,8,9,10,20,30,40,50,
60,70,71,72,73,74,75,76,77,78,79,89,99,109,119,129,139,140,
141,142,143,144,145,146,147,148,149
};
for (int i = 0; i < indexNumbers.length; i++)
{
array [indexNumbers[i]] = ' ';
}
for (int index = 0; index < array.length; index ++)
{
if (index % 10 == 0 && index > 0)
System.out.println();
System.out.print (array[index]);
}
//Now, to reverse the letter
System.out.println();
System.out.println();
int lines = 5;
for (int i = 0; i< array.length; i++){
if (i >= lines)
lines += 10;
char temp = array [i];
array [i] = array [lines - i - 1];
array [lines - i - 1] = temp;
}
for (int index = 0; index < array.length; index ++)
{
if (index % 10 == 0 && index > 0)
System.out.println();
System.out.print (array[index]);
}
}
}
编辑:是的…设计在空间,其他一切都是星号.
最佳答案 你的逆转有点困惑….如果你在两个循环中做到这一点会更容易.
for (int row = 0; row < (array.Length / 10); row++)
{
for (int col = 0; col < 5; col++)
{
int rowStart = row * 10;
int rowEnd = rowStart + 9;
char temp = array[rowStart + col];
array[rowStart + col] = array[rowEnd - col];
array[rowEnd - col] = temp;
}
}
