例如,int numColumns = array[0].length;将获取第一行的列数。 示例代码: 以下是一个示例代码,展示了如何使用length属性获取并打印二维数组的行数和每行的长度: java public class TwoDimensionalArrayLengthExample { public static void main(String[] args) { // 定
下面是一个完整的示例代码,演示如何判断二维数组的长度: publicclassTwoDimensionalArrayLength{publicstaticvoidmain(String[]args){int[][]array=newint[3][4];introws=array.length;intcolumns=array[0].length;System.out.println("二维数组的行数为:"+rows);System.out.println("二维数组的列数为:"+columns...
