## transient 用來修飾成員變量的,用不用transient修飾對成員變量完全沒有影響.但是序列化的時候有用,如果一個成員變量被transient修飾,那么序列化的時候 會被忽略. ## 實例 ~~~ public class Person implements Serializable { private transient String name; private int age; public Person(String name, int age) { this.name = name; this.age = age; } @Override public String toString() { return "Person{" + "name='" + name + '\'' + ", age=" + age + '}'; } } ~~~ ~~~ ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream("1.txt")); Person p = (Person) objectInputStream.readObject(); System.out.println(p); objectInputStream.close(); ~~~ 結果 ``` Person{name='null', age=20} ```
