java---实现数组的输出

class ArrayShow 
{
	public static void main(String[] args) 
	{
		int a[][] = {{1,2,3},{4,5,6},{7,8,9}};
		int a2[][] = new int [3][];

		//输出数组
		for (int i = 0; i < 3; i++)
		{
			for (int j = 0; j < 3; j++)
			{
				System.out.print(a[i][j]);
			}
			System.out.println();
		}

		//具体输出
		System.out.println("具体输出");
		for (int i = 0; i < 3; i++)
		{
			for (int j = 0; j < 3; j++)
			{
				System.out.println("a["+i+"]["+j+"]="+a[i][j]+" ");
			}
		}
		//复制并输出
		a2 = a.clone();
		System.out.println("输出复制后的值：");
		for (int i = 0; i < 3; i++)
		{
			for (int j = 0; j < 3; j++)
			{
				System.out.println("a2["+i+"]["+j+"]="+a[i][j]+" ");
			}
		}
