Question

所以我正在尝试创建一个代码生成器，如果输入变量名称，将生成setter和getter方法：“int nums”或“String words”等。

我的问题是它只能输入一个

如果您输入多个变量，它会给我这个：

输入

int nums
String words

输出

public int set nums
string()
{
    return nums
string;
}

public int get nums
string()
{
    return nums
string;
}

我的方法是使用静态和非静态方法的模板创建两个文本文件，例如它们如下所示：

public <<Variable>> set <<Name>>()
{
    return <<Name>>;
}

public <<Variable>> get <<Name>>()
{
    return <<Name>>;
}

我知道setter不应该返回任何东西，但我只是想在我继续前进这个第一步。

然后我将这些存储在一个字符串中并从用户那里获得输入并使用他们的输入替换＆lt;＆gt;和＆lt;＆gt;字符串的元素。这是我的代码注意：我使用Swing将其设为GUI

import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

  */
 public static void replace(ArrayList<String> inputs, String methods, JTextArea output)
 {
     for(int i = 0; i < inputs.size(); i+=2)
     {
         methods = methods.replaceAll("<<Variable>>", inputs.get(i));
     }

     for(int i = 1; i < inputs.size(); i+=2)
     {
         methods = methods.replaceAll("<<Name>>", inputs.get(i));
     }

     output.setText(methods);

如何解决问题？

Answer 1

问题的原因是......

 String[] temp = inputTextArea.getText().split(" ");

如果您使用

的输入

int nums
String words

然后你会得到一些类似......的数组

[0] int
[1] nums\nString
[2] words

......这不是你想要的......

首先需要将输入拆分为行...

 String[] lines = inputTextArea.getText().split("\n");

然后，对于每一行，将其拆分为单词......

for (String line : lines) {
    String[] temp = line.split(" ");
}

然后我会使用output.append(methods)或更改replace方法以返回String ...

ps：我知道这可能是一个＆＃34;个人＆＃34;项目，但你真的应该避免使用null布局，像素完美的布局是现代ui设计中的错觉。影响组件个体大小的因素太多，您无法控制。 Swing旨在与布局管理器一起工作，放弃这些将导致问题和问题的结束，您将花费越来越多的时间来纠正。
