//抛出一个异常 (.ArrayIndexOutOfBoundsException: Index 9 out of bounds for length 9) //bascially what im试图做它说例如输入是这样的：

3

3

//宽度为 3，高度为 3，我试图用字符串的字符填充数组 //我对 java 有点陌生，但我喜欢解决这样的难题，这个难题正在吞噬我

不是 100% 确定你在问什么，但我猜你正在寻找这样的东西：

        for (int i = 0; i < h; i++) {
            String line;
            while (true) {
                line = in.nextLine();
                if (line.length() == w)
                    break;
                else
                    System.out.println("Please enter a string of length "+w);
            }
            for(int j = 0; j < w; j++){
                answer[i][j] = line.charAt(j);
                System.out.print(answer[i][j]);
            }
            System.out.println();
        }
