静态变量的声明和赋值是分开的，变量名的声明先加载，赋值是按照代码顺序执行。java

public class Test {
    static {
        NAME = "xing";
    }
    private static String NAME = "tong";
    private static String namee = "wang" + NAME;
    public static void main(String[] args){
        System.out.println(namee);
    }
}

执行结果：wangtongcode

public class Test {
    private static String NAME = "tong";
    static {
        NAME = "xing";
    }
    private static String namee = "wang" + NAME;
    public static void main(String[] args){
        System.out.println(namee);
    }
}

执行结果：wangxingclass

public class Test {
    private static String NAME = "tong";
    private static String namee = "wang" + NAME;
    static {
        NAME = "xing";
    }
    public static void main(String[] args){
        System.out.println(namee);
    }
}

执行结果：wangtong变量
