商苑面馆：数组

Java一维数组

• 面馆老板现在需要重新定义一份菜单，使用一维数组，他有几种方法呢 ？

新建类Array1:

package test;

public class Array1 {
    public static void main(String []args) {
       //System.out.println("Hello World!");
	   String [] menu = new String[5];
	   menu[0] = "炸酱面";
	   menu[1] = "刀削面";
	   menu[2] = "安徽板面";
	   menu[3] = "葱油拌面";
	   menu[4] = "兰州拉面";
	   //String [] menu = {"阳春面","油泼面","鸡汤面","火鸡面","安徽板面"};
	   for(int i=0;i <5;i++){
			System.out.println(menu[i]);
		}
	   
	  
    }
}

Java二维数组

• 面馆老板现在需要根据周一到周五，每天推出三款特价面，利用二维数组，他该怎么做呢 ？

新建类Array2:

package test;

public class Array2 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String [][] price = {{"炸酱面","方便面","版面"},{"刀削面","拉面","炒面"},{"牛肉面","鸡汤面","红烧面"},{"炒面","拉面","刀削面"},{"牛肉面","红烧面","鸡汤面"}};
		
		for(int i=0;i<5;i++) {
			System.out.println("周"+(i+1));
			for(int j = 0;j<3;j++) {
				System.out.println(price[i][j]);
			}	
		}
	}

}
