代码在eclipse中编译但不在命令行上

我曾经在Java类中写过这一行。这在Eclipse中编译好但不在命令行上。代码在eclipse中编译但不在命令行上

这是

  • 的Eclipse 3.3
  • JDK 1.5
  • Windows XP专业版

任何线索？在命令行上给出

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,

报告的错误是什么？ – Liam 2008-09-22 15:57:43

从this forum on Sun's support site ，没有一种方法可以超过64 KB长：

当你有代码（伪）像下面...

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

    public MyClass() 
    { 
    }

编译器最终生成的代码基本上看起来像下面这样。

class MyClass 
{ 
    private String[] s; 

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

而且正如所述，java将所有方法都限制为64k，即使是编译器创建的方法也是如此。

这可能是Eclipse做了些鬼鬼祟祟的事情来解决这个问题，但我向你保证在Eclipse中这仍然是可能的，因为我看到了同样的错误信息。一个更好的解决方法就是从一个静态文件中读取，像这样：

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); 
    } 
    } 
}

很难从商提供的有什么说什么，但猜测是

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

什么是编译错误？

你可以在虚拟类中分离出问题来演示吗？

很难说为什么你的命令行编译错误，但是......

既然你有一个可怕的很多“幻数”，有可能会比硬编码数组文本的更好方法。

考虑

  • 使用静态初始化块来初始化列表
  • 阅读，让您的数字一个XML文件，并使用你的类，它读取XML回到你想要的数据类型（无论是列表或字节[]

你有什么似乎编译。

如果可能的话，我会建议试图嵌入罐中的资源，使用 ClassLoader.getResourceAsStream（）。

我不知道为什么你的源硬编码的图像（图标），而不是使用某种形式的资源。

，如果你使用的是Windows 写

设置JAVA_HOME = C：\ Program Files文件....路径JDK 的路径应该是jdk的路径我的电脑上没有JRE 是C：\ Program Files \ Java \ jdk1.6。0_07

警告：路径应无法做到不包围引号（“）CMD的的自动填充使他们

unix系统上使用

出口JAVA_HOME = PATH TO JDK！（引号是可以接受的）

你确定你的命令行和Eclipse使用Java编译器和相同的编译环境的相同版本？要找到您在命令行中使用的Java版本，请执行以下操作：Java -version

Eclipse拥有自己的编译器。 Eclipse JDT编译器似乎以不同于javac的方式处理数组。
