java - Java中全局变量的创建顺序

Question

是否保证以下实例按顺序创建？例如，我们可以假设 B 总是在 E 之前创建吗？

public class Example {
  public static final Integer A = new Integer(1);
  public static final Integer B = new Integer(2);
  public static final Integer C = new Integer(3);
  public static final Integer D = new Integer(4);
  public static final Integer E = new Integer(5);
  public static final Integer F = new Integer(6);
}

Answer 1

只要确认语句按顺序执行，很可能会按顺序创建实例/对象，或者按顺序分配内存。

此外，正如 Kevin Krumwiede 所指出的那样，您的代码甚至无效，您缺少所有变量/引用的数据类型声明...

public static final Integer A = new Integer(1);
public static final Integer B = new Integer(2);
public static final Integer C = new Integer(3);
public static final Integer D = new Integer(4);
public static final Integer E = new Integer(5);
public static final Integer F = new Integer(6);
