為啥不能調用父類變量？
父類Animal
package?com.imooc;
public?class?Animal?{
//父類中的成員變量
public?String?name;
public?int?age;
private?int?weight;
public?void?eat()?{
????System.out.println("吃東西");
}
}子類Dog
package?com.imooc;
public?class?Dog?extends?Animal?{
}測試類Initial
package?com.imooc;
public?class?Initial?{
????Dog?dog?=?new?Dog();
????dog.age?=?2;
????dog.name?=?"xiaotian";
????}在測試類調用父類成員變量時報錯
dog.age = 2;
dog.name = "xiaotian";
以上兩句報錯
錯誤紅線在age和name下
