哪个会加载第一个静态变量或静态块？ [英] Which will be loaded first static variable or static block?

问题描述

我的一个朋友问我哪个会加载第一个静态变量或静态块。

One of my friends asked me that which will load first static variable or static block.

我的答案指向静态变量。

My answer points to static variable.

所以他给了我两个方程并说要区分它们

b $ b 第一个方程式

So he gave me two equations and said to differentiate between them
First Equation

public class Some {
    public static void main(String args[])
    {
        System.out.println(Some.x);
    }
    static {
        System.out.println(Some.x);
    }
    static int x=90;
}

O / P：0 90

O/P: 0 90

第二个等式

public class Some {
    public static void main(String args[])
    {
        System.out.println(Some.x);
    }
    static int x=90;
    static {
        System.out.println(Some.x);
    }
}

O / P：90 90

O/P: 90 90

我试图对字节码进行反编译，发现它对于上述两个方程都是一样的。
请帮我区分它们。
当静态变量初始化时我很困惑。

I tried to decompile the byte code and found it's same for both the above equation. Please help me to differentiate between them. I am confused when the static variable will initialised.

推荐答案

静态块按它们出现的顺序初始化源文件。
关于堆栈溢出已经有几个问题了...
这个问题对你有好处： Java：初始化静态最终字段的顺序是什么？

Static blocks are initialised in the order they appear in the source file. There are several questions relating to this on stack overflow already... This one has a good answer for you: Java : in what order are static final fields initialized?
