Output: reference to A is ambiguous

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

I just tried that and did not get any errors, and the final code prints the correct value.

I am sorry. I have corrected the code.

Now you have different package names to the ones you are importing.

Your problem really stems from the fact that you have two definitions of A. So unless you use the fully qualified name the compiler cannot be sure which one you are referring to.

Try:

Java

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);
}
}

Thanks. That works. Is this the only solution?

Neither would I, but these days people seem to do what they want rather than what they should.

Please read this document[^]

This one provides various examples on how you can declare

Improving Richard MacCutchan 's answer

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);
}
}

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);
}
}

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);
}
}

or

package org.sd;

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