java - 代码在 eclipse 中编译，但不在命令行中编译

转载作者：行者123 更新时间：2023-12-02 14:30:35

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

已开启

Eclipse 3.3
JDK 1.5
Windows XP 专业版

有什么线索吗？

命令行给出的错误是:

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,

最佳答案

取自this forum on Sun's support site ，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();
  }

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 Eclipse 正在做一些偷偷摸摸的事情来解决这个问题，但我向您保证这在 Eclipse 中仍然是可能的，因为我已经看到了相同的错误消息。更好的解决方案是只从静态文件中读取，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);
    }
  }
}
