/*

 文件名：Main.java 
 */public class Main {
   public static void main(String args[]) {
      String[][] data = new String[2][5];
      System.out.println("第一维数组长度: " + data.length);
      System.out.println("第二维数组长度: " + data[0].length);
   }}

The output result of running the above code is:

第一维数组长度: 2 
第二维数组长度: 5
