如何直接从另一个类访问变量（即不使用类名或对象）？

Question

Suppose, I've a class TestA which has variable int Age like -

class TestA{
  int Age = 25;
}

and I want to access it from class TestB without using class name(in this case, I'll have to declare Age as static ) and without creating object of TestA

How can we achieve this in Java?

Note: TestB is not subclass of TestA

Answer 1

Define that field as static and do something like:

 import static TestA.Age;

 class TestB {
    public void test() {
        System.out.println(Age);
    }
 }
