In this tutorial, we will see how to loop diagonally through a two-dimensional array. The solution that we provide can be used for a square two-dimensional array of any size. 2. Two-Dimensional Array The key in working with elements of an array is knowing how to get a specific element ...

增强for循环的索引 在for循环中声明的本地 其实就是类似JS的var变量,用法如下: var numbers = List.of(1, 2, 3, 4, 5); // inferred value ArrayList<String> // Index of Enhanced For Loop for (var number : numbers) { System.out.println(number); } // Local variable declared in a loop ...
