2

我曾经在一个 Java 类中写过这一行。这在 Eclipse 中编译得很好，但在命令行上却没有。

这是在

  • 日食 3.3
  • JDK 1.5
  • Windows XP 专业版

有什么线索吗？

命令行上给出的错误是：

Icons.java:16: code too large
            public static final byte[] compileIcon = { 71, 73, 70, 56, 57, 97, 50,
                                       ^

有问题的代码行是：

public static final byte[] compileIcon = { 71, 73, 70, 56, 57, 97, 50,

取自Sun 支持站点上的这个论坛，任何方法的长度都不能超过 64 KB：

当您有如下代码（伪）时...

class MyClass
{
  private String[] s = { "a", "b", "c"}

  public MyClass()
  {
  }

编译器最终生成的代码基本上如下所示。

class MyClass
{
  private String[] s;

  private void FunnyName$Method()
  {
    s[0] = "a";
    s[1] = "b";
    s[2] = "c";
  }
  public MyClass()
  {
    FunnyName$Method();
  }

并且如前所述，java 将所有方法限制为 64k，甚至是编译器创建的方法。

可能是 Eclipse 正在偷偷摸摸地解决这个问题，但我向您保证，这在 Eclipse 中仍然是可能的，因为我看到了相同的错误消息。更好的解决方案是从静态文件中读取，如下所示：

public class Icons
{
  public static final byte[] compileIcon;
  static
  {
    compileIcon = readFileToBytes("compileIcon.gif");
  }
  //... (I assume there are several other icons)
  private static byte[] readFileToBytes(String filename)
  {
    try {
      File file = new File(filename);
      byte[] bytes = new byte[(int)file.length()];
      FileInputStream fin = new FileInputStream(file);
      fin.read(bytes);
      fin.close();
    }
    catch (Exception e) {
      e.printStackTrace();
      System.exit(1);
    }
  }
}

你所拥有的似乎可以编译。

如果可能，我建议尝试将资源嵌入 Jar 并使用 ClassLoader.getResourceAsStream()。

Eclipse 有它自己的编译器。Eclipse JDT 编译器处理数组的方式似乎与 javac 不同。

很难说为什么你有命令行编译错误，但是......

由于您拥有大量“幻数”，因此可能有比硬编码数组文字更好的方法。

考虑

  • 使用静态初始化程序块初始化列表
  • 读取一个包含您的数字的 XML 文件，并使用您的类读取 XML 以返回您想要的数据类型（无论是 List 还是 byte[]

提供确切的错误消息也将帮助我们帮助您...
我想知道为什么您在源代码中硬编码图像（图标），而不是使用某种形式的资源。

从提供的内容很难说，但猜测是

  1. Eclipse 中的 JVM 与命令行不同。
  2. 命令行中的错误类路径设置。

什么是编译错误？

你能把问题隔离在一个虚拟类中进行演示吗？

如果你在 Windows 上写

设置 JAVA_HOME=C:\Program Files.... JDK 的路径 路径应该是 jdk 路径而不是我的 PC 上的 jre 是 C:\Program Files\Java\jdk1.6.0_07

警告：路径不应该被引号 (") cmd 的自动补全放置它们！

在类 Unix 系统上使用

export JAVA_HOME= PATH TO JDK（允许引用）

您确定您的命令行和 eclipse 使用相同版本的 Java 编译器和相同的编译设置吗？要在命令行类型中找到您正在使用的 Java 版本：Java -version
