java public class NestedLoopExample { public static void main(String[] args) { // 外循环:控制行数 for (int i = 1; i <= 3; i++) { System.out.println("外循环迭代: " + i); // 内循环:控制列数 for (int j = 1; j <= 2; j++) { Sys
public static void main(String[] args) { for (int i = 0; i < 5; i++) { System.out.println("Iteration: " + i); } } } 上面的代码将输出0到4的数字,每一行一个。 3. 多重for循环 在实际编程中,有时需要嵌套使用for循环。例如,打印一个矩形的星号图案: public class NestedForLoopExample...

4. Nested Loops It’s possible to nest one for-loop in another for-loop. This approach is used to process multidimensional structures like tables (matrices), data cubes, and so on. As an example, the following code prints the multiplication table of numbers from 1 to 9 (inclusive). ...
The problem we run into in the nested version is that we can’t use toArray() in the inner loop since the inner loop is part of a map function which is expecting an int not an int[]. This means we have to use another trick:...
