package one;
interface Add{
public void addNamber(int a,int b);
}
interface Minus{
public int minusNamber(int a,int b);
}
class Account implements Add,Minus{
public void addNumber(int a,int b){
int val;
val=a+b;
System.out.println("a+b= "+val);
}
public int minusNumber(int a,int b){
int val;
val=a-b;
System.out.println("a-b= "+val);

}
}
public class Interface_a{
public static void main(String[] args){
Add obj=new Account();
obj.addNamber(10,20);
Minus obj1=new Account();
obj1.minusNamber(100,50);
}
}
这段程序的出错提示如下:
Interface_a.java:8: one.Account is not abstract and does not override abstract method addNamber(int,int) in one.Add
class Account implements Add,Minus{

小弟实在是不知道这该怎么改了,望各位大哥指教呀。
