在Java中，静态方法内部声明的变量本身是静态的吗？ [英] In Java, are variables declared inside static methods themselves static?

问题描述

假设如下：

private static boolean A()
{
  int parsedUntil = 0;
  ...
  ...
  ...
}

is parsedUntil被认为是一个静态变量？我注意到我不能在静态函数中声明它是静态的。

Is parsedUntil considered to be a static variable? I noticed that I can't declare it as static inside this static function.

后续问题：我读到静态变量只会被初始化一次。这是否意味着我第一次调用函数A（）时该值将被设置为零，但每隔一次我调用A（），该行被省略？

Follow-up question: I read that a static variable will only be initialized once. Does that mean the first time I call function A() the value will be set to zero, but every other time I call A(), that row is omitted?

推荐答案

不，它不是静态变量。这是一个局部变量。方法中声明的任何变量都是局部变量。如果你想要一个静态变量，你必须在方法之外声明它：

No, it's not a static variable. It's a local variable. Any variable declared in a method is a local variable. If you want a static variable, you have to declare it outside the method:

private static int parsedUntil = 0;

无法声明只能在单个方法中使用的静态变量。

There's no way of declaring a static variable which can only be used within a single method.
