java getAClass()问题，提示出现下面错误 Exception in thread "main" java.lang.Error: Unresolv
/**
*
*/
private String height;
public String getHeight() {
return height;
}
public void setHeight(String height) {
this.height = height;
}
// 下面是继承Baseclass类Extendclass
class Extendclass extends Baseclass {
private String width;
public String getWidth() {
return width;
}
public void setWidth(String width) {
this.width = width;
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
Baseclass baseclass1 = new Extendclass();
Baseclass baseclass2 = new Baseclass();
System.out.println(baseclass1.getClass().getSimpleName());// 实际运行的是继承类Extendclass
System.out.println(baseclass2.getClass().getSimpleName());// 实际运行的是Baseclass
System.out.println(Baseclass.class.getSimpleName());// 加载时类名
System.out.println(Extendclass.class.getSimpleName());// 加载时类名
}
}

No enclosing instance of type Baseclass is accessible. Must qualify the allocation with an
enclosing instance of type Baseclass (e.g. x.new A() where x is an instance of Baseclass).
解释的意思应该是内部类不能实现化，我认为就这个意思，如果你把位置换一下的话，就可以了
回该是这样的
-------------------------------------------------------------------------------
package first.test;
public class Baseclass {
/**
*
*/
private String height;
public String getHeight() {
return height;
}
public void setHeight(String height) {
this.height = height;
}
// 下面是继承Baseclass类Extendclass
public static void main(String[] args) {
// TODO Auto-generated method stub
Baseclass baseclass1 = new Extendclass();
Baseclass baseclass2 = new Baseclass();
System.out.println(baseclass1.getClass().getSimpleName());// 实际运行的是继承类Extendclass
System.out.println(baseclass2.getClass().getSimpleName());// 实际运行的是Baseclass
System.out.println(Baseclass.class.getSimpleName());// 加载时类名
System.out.println(Extendclass.class.getSimpleName());// 加载时类名
}
}
class Extendclass extends Baseclass {
private String width;
public String getWidth() {
return width;
}
public void setWidth(String width) {
this.width = width;
}
}
