javax.security.cert.X509Certificate vs java.security.cert.X509Certificate?
提问by Narobik Olga
Did you spot the difference in the title? (for me, it took some time)
你发现标题的不同了吗？（对我来说，花了一些时间）
So I used bouncy castle with connection to java.security.cert.X509Certificatein order
to create certificates. Now I'm looking for a way to create a java.security.cert.X509Certificatefrom raw bytes. I haven't any method to do this in
java.security.cert.X509Certificatebut there is one(the getInstance static method) in
javax.security.cert.X509Certificate.
所以我使用了连接到的充气城堡java.security.cert.X509Certificate来创建证书。现在我正在寻找一种java.security.cert.X509Certificate从原始字节创建一个的方法。我没有任何方法可以做到这一点，
java.security.cert.X509Certificate但
javax.security.cert.X509Certificate.
The problem is I cannot cast a javax.security.cert.X509Certificateto java.security.cert.X509Certificate.
问题是我不能投射javax.security.cert.X509Certificate到java.security.cert.X509Certificate.
Any ideas on what to do, to transform raw bytes into a java.security.cert.X509Certificate?
关于如何将原始字节转换为java.security.cert.X509Certificate?
Also, what's the differences between the one abstract class and the other class? Why does java has two of them with different functionality?
另外，一个抽象类和另一个类之间有什么区别？为什么java有两个具有不同功能的？

The javax version is deprecated. Use CertificateFactoryto generate a certificate from raw bytes. There is an example in the javadocs.
不推荐使用 javax 版本。使用CertificateFactory从原始字节生成证书。javadocs中有一个例子。
回答by Venu
This happened for me because I am using j2se but imported javax classes. Certificate and X509Certficate classes exists both in J2SE and in J2EE.
这发生在我身上，因为我使用的是 j2se 但导入了 javax 类。Certificate 和 X509Certficate 类存在于 J2SE 和 J2EE 中。
Imports in J2SE - Not javax.security...
J2SE 中的导入 - 不是 javax.security...
import java.security.KeyStore;
import java.security.cert.CertificateFactory;
import java.security.cert.X509Certificate;
import java.security.cert.Certificate;
导入 java.security.cert.Certificate;
Not these.
不是这些。
import javax.security.cert.X509Certificate;
