transient has the meaning of "temporary" and "ephemeral". We have learned about Serializable and Java serialization. When we do not want to serialize certainvariablesYou can set this variable to transient. Transient is a keyword in the Java language and is used to indicate that a domain is not part of the serialization of theobject.transient indicates that aattributeis temporary and will not be serialized.

public class TransientDemo implements Serializable{ /** * */ private static final long serialVersionUID = 1L; private transient String name; private String password; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException { // TODO Auto-generated method stub String path="D:"+File.separator+"object.txt"; File file=new File(path); TransientDemo transientDemo=new TransientDemo(); transientDemo.setName("姓名"); transientDemo.setPassword("密码"); ObjectOutput output=new ObjectOutputStream(new FileOutputStream(file)); output.writeObject(transientDemo); ObjectInput input=new ObjectInputStream(new FileInputStream(file)); TransientDemo demo=( TransientDemo )input.readObject(); System.out.println(demo.getName()+demo.getPassword()); } }
