public class BinaryArray
{
	public static void main(String[] args)
	{
		//二维数组定义和初始化
		int[][] arrs={
			{1,2,3},
			{4,5,6},
			{6,8,9}
		};
		//二维数组遍历输出
		for(int i=0;i<arrs.length;i++)
		{
			for(int j=0;j<arrs[i].length;j++)
			{
				System.out.print(arrs[i][j]);
			}

			System.out.println("");
		}

		//增强for循环 是jdk 5.0 以后才有的新的特性
		String[] names={"黎明","张胜","李阳"};
		for(String name:names)
		{
			System.out.print(name+",");
		}


		//定义一个课程的二维表结构
		String[][] courses={
			{"C001","英语"},
			{"C002","数学"},
			{"C003","Java编程"}
		};
		System.out.println("\n---------------------");
		//输出
		for(String[] rows:courses)
		{
			for(String col:rows)
			{
				System.out.print(col+",");
			}
			System.out.println("");
