在Java中,没有内置的fillArray()方法来填充二维数组。然而,我们可以使用循环结构和Arrays.fill()方法来实现这个功能。 首先,我们需要创建一个二维数组,并初始化其大小和元素类型。例如,我们可以创建一个3行4列的整数类型的二维数组: 代码语言:txt 复制
int[]array=newint[5];Arrays.fill(array,1);Arrays.fill(array,2,4,3); 1. 2. 3. 在这个示例中,我们首先将数组中的所有元素填充为1,然后再次调用fill()方法,将索引从2到3的元素填充为3。最终,数组的内容将变为[1, 1, 3, 3, 1]。 Array.fill()方法的注意事项 在使用Array.fill()方法时,需要...
这个主要作用是数组填充用，下面的例子你测下就明白了，比如 public class ArrayFill { public static void main(String[] args) { boolean[] a1 = new boolean[15];java.util.Arrays.fill(a1, true);for (int i = 0; i < 15; i++) { System.out.println(a1[i] + "\t " + i);...
