java import 引入类中已经有了变量，引入的变量无效

import static packagename.classname.variablename

variablename重复的话，上面的import static packagename.classname.variablename会无效

 

package ex7;

public class Sample {
    public final static int VALUE = 100;
}

 

package ex7;

import static ex7.Sample.VALUE;

public class Main {
    private final static int VALUE = 820;

    public static void main(String...addddd) {
        System.out.println(VALUE);
    }
}

 

 

 

到此结束。
