java流的问题
package untitled1;import
import
import javax.crypto.CipherInputStream;
import
import
import javax.crypto.CipherOutputStream;
import *;
public class CipherLiu {
public static void main(String[] args) {
File f = new File("d:\\User.db");
InputStream is = null;
try {
is = new FileInputStream(f);
}
catch (FileNotFoundException ex) {
}
CipherInputStream cis = new CipherInputStream(is);
}
}
报错:CipherInputStream()has protected acess in javax.crypto.CipherInputStream
怎么解决?
