关于#java#的问题：Java语言怎么编写十字形的字母输出，也就是同时从左边和上面两个方向都能输出字母，比如输入apple 和 elect输出为

String str1 = "apple";
String str2 = "elect";
String commonLetters = "";

for (int i = 0; i < str1.length(); i++) {
    char letter1 = str1.charAt(i);
    for (int j = 0; j < str2.length(); j++) {
        char letter2 = str2.charAt(j);
        if (letter1 == letter2) {
            commonLetters += letter1;
            break;
        }
    }
}

int size = commonLetters.length() + 2;

char[][] crossPattern = new char[size][size];

// 填充数组
for (int i = 0; i < size; i++) {
    for (int j = 0; j < size; j++) {
        crossPattern[i][j] = ' ';
    }
}

// 替换共同的字母
int center = size / 2;
crossPattern[center][center] = commonLetters.charAt(0);
int x = center - 1;
int y = center;

for (int i = 1; i < commonLetters.length(); i++) {
    crossPattern[y][x] = commonLetters.charAt(i);
    x--;
    y++;
}

// 打印数组
for (int i = 0; i < size; i++) {
    for (int j = 0; j < size; j++) {
        System.out.print(crossPattern[i][j]);
    }
    System.out.println();
}
