Java-嵌套循环-无法获取任何输出

我提出这个想法是为了模拟植物的生长方式。这个想法是基于分形几何，以及分形几何如何解释植物中树枝和其他结构的重复。不过，我是一个编程新手，所以我想我应该测试一下重复某些东西的基本逻辑。下面是我用Java写的

/*
Java program:   plant.java

This program runs a loop simulating plant growth.
The idea is that the plant will continue to have "repeated"
growth and that it will stop (or slow down to a crawl) at some point, 
in this case at 100 branches.

*/

public class plant
{
    public static void main (String [] poop)
    {
        int current_growth = 0, limit = 100; //plant growth starts at ZERO and is limited to 100
        String word = "branches";

        while (current_growth > 0)
        {
            //here, we are checking to see if the plant has grown just 1 inch.
            //this is important just for grammatical purposes
            if (current_growth == 1)
            {
                word = "branch"; //this changes the "word" to branch instead of branches
            }


        System.out.println("Your plant has grown " + current_growth + " " + word);
        //if you put the singular count check here, it doesn't work at all
        current_growth = current_growth + 1;

            if (current_growth > 0)
            {
            System.out.println("Your plant has grown " + current_growth + " " + word);
            }
            else
            {
            System.out.println("Your plant will no longer grow.");
            } // end else
        } //end while loop
    } //end main method
} //end class

我做了以下工作：

将其保存在我的Java存储库中，并将我的存储库更改为指向 那里

使用MacBook Air:Java bdeely$javac plant.Java调用/编译代码

使用

macbookair:Java-bdeely$Java-plant运行代码

问题是： -根本没有产出。命令提示符返回为空，如

macbookair:javabdeely$

我相当肯定我在这里犯了一些很大的新手错误。有人知道我如何让这段代码给我重复从0到100的循环的输出吗

谢谢

因为当前的增长被初始化为

0

while (current_growth > 0) // never becomes true

---

这是因为在开始时，您的

当前增长=0

，但当条件为

（当前增长>0）

为什么不使用

进行
循环：

for(current_growth = 0; current_growth < limit; ++current_growth)

for（当前增长=0；当前增长
您当前的
增长率为0。在while
编辑中使其
=0
：

 public class plant
    {
        public static void main (String [] poop)
        {
            int current_growth = 0, limit = 1;//set limit to 1 //plant growth starts at ZERO and is limited to 100
        String word = "branches";

    while (limit<=100)// for 100 iterations limit
    {
        //here, we are checking to see if the plant has grown just 1 inch.
        //this is important just for grammatical purposes
        if (current_growth == 1)
        {
            word = "branch"; //this changes the "word" to branch instead of branches
        }


    System.out.println("Your plant has grown " + current_growth + " " + word);
    //if you put the singular count check here, it doesn't work at all
    current_growth = current_growth + 1;

        if (current_growth > 0)
        {
        System.out.println("Your plant has grown " + current_growth + " " + word);
        }
        else
        {
        System.out.println("Your plant will no longer grow.");
        } // end else
       limit=limit+1;// increment
    } //end while loop
} //end main method
} //end class

公共级工厂
{
公共静态void main（字符串[]poop）
{
int current_growth=0，limit=1；//将limit设置为1//植物生长从零开始，限制为100
String word=“分支”；
while（limitCheck你的
while
循环条件。它不是真的，因此执行不会进入它。你可以使用并享受：）谢谢你的替代方法。我将使用for循环
