Processing之旅-----【5课数组实验课】

同学们准备好要上机了吗？//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
//经过深思熟虑，决定先折腾Array类型
//因为数组类型是最常用也是非常高效的一种数据结构
//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。
//
//
//
int[] m_Array = new int;
int Sum;
void setup(){
size(512, 512,P3D);
background(#287CE8);
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
    m_Array=i;
    Sum+=m_Array;
    if (m_Array==0){
      print(m_Array);
    }
    else {
      print("+"+m_Array);//边赋值边输出。
    }
   
}
println("="+Sum);

}
//让我们做一些比较好玩的操作。
void draw(){
for(int i=0;i<10;i++)
{
    line(random(0, 512), random(0, 512), random(0, 512), random(0, 512), random(0, 512), random(0, 512));
}
}
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:):)
