如何将父类属性 在子类中使用
例如
class Animal
{
public String location;
public void run()
{
System.out.println("Animal is running");
}
}
//定义子类Tiger 继承自父类Animal 给属性location赋值字符串"辽宁"
怎么写？
例如
class Animal
{
public String location;
public void run()
{
System.out.println("Animal is running");
}
}
//定义子类Tiger 继承自父类Animal 给属性location赋值字符串"辽宁"
怎么写？
class Tiger extends Animal
{
location = "辽宁";
}
这样就可以了,父类中的东西子类是可以随意调用的
super. location = "ddd";
class Tiger extends Animal
{
public Tiger()
{
location = "辽宁";
}
}
//最好将父类的location设置为protected
public class Animal {
public String location;
public String getLocation() {
return location;
}
public Animal() {
}
public void setLocation(String location) {
this.location = location;
}
}
public class Tiger extends Animal {
public static void main(String[] args) {
Animal a=new Tiger();
Animal a1 = new Animal();
a1.setLocation("沈阳");
System.out.print(a1.location);
}
}
public的都可以继承的
