An interface in Java without any field and method is a Marker interface. It is used to inform compiler that the class implementing it has some special behavior or meaning. Some of the Marker interfaces are- java.io.Serializable java.rmi.Remote java.util.RandomAccess java.lang.Cloneable Although...
java.security.cert 証明書、証明書の取り消しリスト (CRL)、証明書パスを解析および管理するためのクラスとインタフェースを提供します。 java.security.interfaces RSA Laboratory Technical Note PKCS#1 で定義されている RSA (Rivest, Shamir and Adleman AsymmetricCipher algorithm) 鍵、および NIST ...
java.security.cert 提供用于解析和管理证书、证书撤消列表 (CRL) 和证书路径的类和接口。 java.security.interfaces 提供的接口用于生成 RSA Laboratory Technical Note PKCS#1 中定义的 RSA(Rivest、Shamir 和 Adleman AsymmetricCipher 算法)密钥,以及 NIST 的 FIPS-186 中定义的 DSA(数字签名算法)密钥。 java....
java.lang.Cloneable Although since Java 5 marker interfaces are replaced by annotations and they serve the same purpose as marker interfaces did before but for serializability we still use the interfaces and thetransient keyword. 2.1 Interfaces Every Object Stream class implements either of the...
java.awt.dnd Drag and Drop is a direct manipulation gesture found in many Graphical User Interface systems that provides a mechanism to transfer information between two entities logically associated with presentation elements in the GUI. java.awt.event Provides interfaces and classes for dealing with...
抛出此异常表示已调用类 Object中的clone方法来克隆对象,但该对象的类未实现 Cloneable接口。 class Double Double类在对象中包装基本类型 double的值。 class Enum<E extends Enum<E>> 这是所有Java语言枚举类型的公共基类。 class EnumConstantNotPresentException 当应用程序尝试按名称访问枚举常量并且枚举类型不...
We will discuss the last topic under Interfaces, i.e. Marker Interface in Java. After we are done with the marker interface we will discuss two examples i.e. serializable and cloneable interface in Java. Let’s begin with the Marker interface. ...
The Byte class wraps a value of primitive type byte in an object. class Character The Character class wraps a value of the primitive type char in an object. class Class Instances of the class Class represent classes and interfaces in a running Java application. class ClassCastException Thr...
java.security Provides the classes and interfaces for the security framework. java.security.acl The classes and interfaces in this package have been superseded by classes in the java.security package. java.security.cert Provides classes and interfaces for parsing and managing certificates, certificate ...
