Magic4g 夢幻國度的虛幻世界

Original:
int[][] cords = {
{1,2,3},
{4,5,6}
};
for (int x = 0; x < cords.length; x++) {
for (int y = 0; y< cords[x].leng; y++) {
System.out.println("%2d", cords[x][y]);
}
System.out.println();
}

Enhanced for loop:
for (int[] row : cords) {
for (int value : row) {
System.out.printf("%2d", value);
}
System.out.println();
}
