初学JAVA——代码练习（遍历一个二维数组）

package XQ;

public class YiWeiShuZu {

    public static void main(String[] args) 
    {
        int [][]A = {new int []{1,2,3},new int []{4,5}};
        System.out.println("二位数组长度为"+A.length);
        for (int B=0;B<A.length;B++)
        {
            for (int C=0;C<A[B].length;C++)
            {
                System.out.print(A[B][C]+" ");
            }
            System.out.println();
        }
    }

}
