java 对象输入输出流读写文件的操作实例

java 对象输入输出流读写文件的操作实例

java 支持对对象的读写操作，所操作的对象必须实现Serializable接口。

实例代码：

package vo;  import java.io.Serializable;  public class Animal implements Serializable {   private static final long serialVersionUID = 1L;   private String name;   private Integer weight;   private String color;   private String type;   private Integer age;   private Integer lifetime;   public String getName() {     return name;   }   public void setName(String name) {     this.name = name;   }   public Integer getWeight() {     return weight;   }   public void setWeight(Integer weight) {     this.weight = weight;   }   public String getColor() {     return color;   }   public void setColor(String color) {     this.color = color;   }   public String getType() {     return type;   }   public void setType(String type) {     this.type = type;   }   public Integer getAge() {     return age;   }   public void setAge(Integer age) {     this.age = age;   }   public Integer getLifetime() {     return lifetime;   }   public void setLifetime(Integer lifetime) {     this.lifetime = lifetime;   }   public Animal(String name, Integer weight, String color, String type, Integer age, Integer lifetime) {     super();     this.name = name;     this.weight = weight;     this.color = color;     this.type = type;     this.age = age;     this.lifetime = lifetime;   }   @Override   public String toString() {     return "Animal [name=" + name + ", weight=" + weight + ", color=" + color + ", type=" + type + ", age=" + age + ", lifetime=" + lifetime + "]";   }    }
