输出二维数组

	int arr[][]=new int[][]{{1},{2,3},{4,5,6}};
            
	        System.out.println("二维数组是:");
	                        
	       for (int z=0;z<arr.length;z++);
	 {
	       
	       for (int a=0;a<arr[z].length;a++);
	   {
	       System.out.print(arr[z][a]+" ");
	       }
	       System.out.println() ;
		}
		
    }
