如何从不同的包中访问静态变量？ [英] How to access static variable from different package?

问题描述

package com.gbr;

public class Hai {
public static int A=88;
}

package com.gbr;

public class Hello {
public static int A=99;
}

package org.sd;

import static com.gbr.Hello.*;
import static com.gbr.Hai.*;

class Test13 {
public static void main(String args[]){
	System.out.println(Hello.A);
        System.out.println(Hai.A);
}
}

输出：对A的引用含糊不清



如何访问两个类的静态变量A.还有什么其他方法？



我尝试过：



< b> 我已经执行了上述代码。

Output: reference to A is ambiguous

How do I access the static variable A of both classes. What are other ways?

What I have tried:

I have executed the above codes.

package org.sd;

class Test13 {
public static void main(String args[]){
	System.out.println(com.gbr.Hello.A);
        System.out.println(com.gbr.Hai.A);
}
}

或

or

package org.sd;

import com.gbr.Hello;
import com.gbr.Hai;
class Test13 {
public static void main(String args[]){
	System.out.println(Hello.A);
        System.out.println(Hai.A);
}
}

或

or

package org.sd;

import static com.gbr.Hello.*;
import com.gbr.Hai;
class Test13 {
public static void main(String args[]){
	System.out.println(A);
        System.out.println(Hai.A);
}
}

}
}

另外阅读此内容以了解歧义 [ ^ ]

尝试：

Try:

package org.sd;
 
import static com.gbr.Hello.*;
import static com.gbr.Hai.*;
 
class Test13 {
public static void main(String args[]){
	System.out.println(com.gbr.Hello.A);
        System.out.println(com.gbr.Hai.A);
}
}
