Processing之旅-----【5课数组实验课】

yangfanconan

同学们准备好要上机了吗？

1. //同学们大家好这节课我们主要来折腾一下Processing里面的一个数据结构
   
2. //经过深思熟虑，决定先折腾Array类型
   
3. //因为数组类型是最常用也是非常高效的一种数据结构
   
4. //在本例中将演示数组的基本操作如声明，初始化，使用等基本用法。
   
5. //
   
6. //
   
7. //
   
8. int[] m_Array = new int[10];
   
9. int Sum;
   
10. void setup(){
    
11.   size(512, 512,P3D);
    
12.   background(#287CE8);
    
13.   for (int i=0;i<10;i++){//这个循环是对m_Array数组进行一个初始化的赋值从0-9共十个元素
    
14.     m_Array[i]=i;
    
15.     Sum+=m_Array[i];
    
16.     if (m_Array[i]==0){
    
17.       print(m_Array[i]);
    
18.     }
    
19.     else {
    
20.       print("+"+m_Array[i]);//边赋值边输出。
    
21.     }
    
22.    
    
23.   }
    
24.   println("="+Sum);
    
25. 
    
26. }
    
27. //让我们做一些比较好玩的操作。
    
28. void draw(){
    
29.   for(int i=0;i<10;i++)
    
30.   {
    
31.     line(random(0, 512), random(0, 512), random(0, 512), random(0, 512), random(0, 512), random(0, 512));
    
32.   }  
    
33. }

复制代码

请运行以上代码查看效果。
如果没有问题您将会看见一下效果。


效果还行吧。同学们主要看对数组的操作。
那么，下课。{:soso__13766225770624999893_3:}

出现上面的错误是什么原因啊
