Java 数组 之 二维数组

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("");
		}
	}
