关于java中的getClass()

getClass() 返回的是运行时类,即类A继承自B,那么A中无论调用this.getClass() 或者super.getClass() 返回的都是A的class

package test;

public class BaseOut
{
    public void out()
    {
        System.out.println("base out"+getClass().getSimpleName());
    }
}

　

package test;

public class ExtentTest extends BaseOut
{
    @Override
    public void out()
    {
        // TODO Auto-generated method stub
        super.out();
        System.out.println("extent out"+getClass().getSimpleName());
    }
    public static void main(String[] args)
    {
        new ExtentTest().out();
    }
}

返回结果
base outExtentTest
extent outExtentTest
