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(""); } } }
