public class BaseClass
{
    public int a = 5;
}
class SubClass extends BaseClass
{
    public int a = 7;
    public void accessOwner()
    {
        System.out.println(a);
    }
    public void accessBase()
    {
        System.out.println(super.a);
    }
    public static void main(String[] args)
    {
        SubClass sc = new SubClass();
        sc.accessOwner();
        sc.accessBase();
    }
}

这个程序显示找不到main方法，咋办。

class xi
{
    public int a = 5;
   
}
public class luntan extends xi
{
    public int a = 7;
    public void accessOwner()
    {
        System.out.println(a);
    }
  
    public void accessBase()
    {
        System.out.println(super.a);
    }
   
    public static void main(String[] args)
    {
       luntan sc = new luntan();
        sc.accessOwner();
        sc.accessBase();
    }
}

public class BaseClass
{
    public int a = 5;
}
class SubClass extends BaseClass
{
    public int a = 7;
    public void accessOwner()
    {
        System.out.println(a);
    }
    public void accessBase()
    {
        System.out.println(super.a);
    }
 
}
   public static void main(String[] args)
    {
        SubClass sc = new SubClass();
        sc.accessOwner();
        sc.accessBase();
    }

public static void main(String[] args)
    {
        SubClass sc = new SubClass();
        sc.accessOwner();
        sc.accessBase();
    }这一段要放在最外面
