Transient has "temporary", "ephemeral" meanings, we have learned about Serializable,java serialization, and when we don't want to serialize it for certain variables, we can set this variable to transient,transient is the Java language keyword To indicate that a domain is not part of the serialization of the object.transient indicates that a property is temporary and will not be serialized.

Public classTransientdemoImplementsserializable{
/**
     *
     */
private static final longSerialversionuid=1L;
Private TransientStringname;
PrivateStringPassword;

 PublicStringGetName() {
returnname;
}

Public voidSetName(String name) {
 This.name= Name;
}

 PublicStringGetPassword() {
returnPassword;
}

Public voidSetPassword(String password) {
 This.Password= password;
}

Public static voidMain(string[] args)throwsFileNotFoundException, IOException, classnotfoundexception {
// TODO auto-generated Method Stub
String path="D:"+file.Separator+"Object.txt";
File file=NewFile (PATH);
Transientdemo transientdemo=NewTransientdemo ();
Transientdemo.setname ("name");
Transientdemo.setpassword ("Password");
ObjectOutput output=NewObjectOutputStream (NewFileOutputStream (file));
Output.writeobject (Transientdemo);
ObjectInput input=NewObjectInputStream (NewFileInputStream (file));
Transientdemo demo= (Transientdemo) Input.readobject ();
System. out. println (Demo.getname () +demo.getpassword ());
}

}

Result password output is null
