OutputStream与InputStream子类

public class ObjectStream {
    static String file="e:\\fileOut.txt";
    public static void main(String[] args) {
        // TODO Auto-generated method stub

//      重点：必须要有类的class文件
//      重点：该类实现Serializable接口，标记型接口
//      ObjectOutputStream.writeObject(person);
//      ObjectInputStream.readObject();
//      重点：类的静态变量无法序列化
//      由于静态变量不属于对象
//      transient修饰成员变量。阻止其序列化。
        func();
        func2();
    }

    private static void func() {
        // TODO Auto-generated method stub

Person类：

public class Person implements Serializable {
    private String name;
    private int age;
    
    public Person(String string, int i) {
        // TODO Auto-generated constructor stub
        this.name=name;
        this.age=age;
    }
}
