/* 声明一个rmi接口 | |
package exam; | |
import java.rmi.*; | |
public interface primeinterface extends Remote { | |
public boolean isPrime(int num) throws RemoteException; | |
} | |
/* 实现这个接口的RMI对象 | |
package exam; | |
import java.rmi.*; | |
import java.rmi.server.*; | |
public class rmiserver extends UnicastRemoteObject implements primeinterface | |
{ | |
protected rmiserver() throws RemoteException { | |
super(); | |
// TODO Auto-generated constructor stub | |
} | |
/** | |
* | |
*/ | |
private static final long serialVersionUID = 1L; | |
@Override | |
public boolean isPrime(int num) throws RemoteException { | |
for(int i = 2;i*i <= num;i ++) | |
if ( num % i == 0) | |
return false; | |
return true; | |
} | |
} | |
然后,我们就可以调用这个rmi接口来判断一个数是不是质数了,分布式的计算1000以内的质数 |
