字段初始化中未处理的异常

Java 是否有任何语法来管理声明和初始化类的成员变量时可能引发的异常？

public class MyClass
{
  // Doesn't compile because constructor can throw IOException
  private static MyFileWriter x = new MyFileWriter("foo.txt"); 
  ...
}

或者这样的初始化是否总是必须移动到我们可以声明的方法中throws IOException或者将初始化包装在 try-catch 块中？

使用静态初始化块

public class MyClass
{
  private static MyFileWriter x;

  static {
    try {
      x = new MyFileWriter("foo.txt"); 
    } catch (Exception e) {
      logging_and _stuff_you_might_want_to_terminate_the_app_here_blah();
    } // end try-catch
  } // end static init block
  ...
}
