一、内存区域划分是什么？

所谓的内存区域划分有 1.栈 2，堆
3. 方法区

二、试例程序

1.代码

代码如下（示例）：

package cn.yunhe.four;

public class liftCycle {
 private String breakfast;
 String lunch;
 String dinner;
 public void setName(String newbreakfast) {
  breakfast = newbreakfast;
 }
 public String getName() {
  return breakfast;
  
 }
 public void foodName() {
  System.out.println("今天早餐是"+getName()+
    "午餐是"+lunch+"晚餐是"+dinner);
  
 }
 

}

 package cn.yunhe.four;

public class qi {

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  liftCycle  liftcycle = new liftCycle();
  liftcycle.dinner = "盖浇饭";
  liftcycle.lunch = "烩面";
  liftcycle.setName("包子");
  liftcycle.foodName();
 }

}
