创建抽象类的对象-错误

Question

I have an abstract class called A .

public abstract class A {
 protected String name;
 A(String name){
  this.name=name;
 }
}

The above class is in the package com.goog.product.demo package

Now from another package i need to load some test data, by creating an object as shown below;

The following class is in the package com.goog.product.test .

public class Test {

 public void loadData(){
  A a =new A("NAME");
 }
}

But, I end up getting an error:

Cannot instantiate the type A

The reason is because; you can't create an object of abstract class. Is there any other way I could load some test values?

Answer 1

Abstract classes cannot be instantiated. You should read this for a better understanding of it.

You can extend your abstract class or have it non-abstract.

Answer 2

I believe what you're trying to do is Construct a new class. In that case, All you have to do is this:

public class Aclass {

    private String name;

    public Aclass(String name) {
        this.name = name;
    }
}

Answer 3

try to extends your class.....

public class B extends A {
