请先看两段代码package com.jadyer.base;<br /> public class User implements java.io.Serializable{<br /> private static final long serialVersionUID = 2035637204889097968L;</p> <p> private Integer age;</p> <p> public Integer getAge() {<br /> return age;<br /> }</p> <p> public void setAge(Integer age) {<br /> this.age = age;<br /> }<br /> }

package com.jadyer.base;<br /> import java.io.Serializable;<br /> public class User implements Serializable{<br /> private static final long serialVersionUID = 2035637204889097968L;</p> <p> private Integer age;</p> <p> public Integer getAge() {<br /> return age;<br /> }</p> <p> public void setAge(Integer age) {<br /> this.age = age;<br /> }<br /> }

同样是实现序列化接口，那么这两种书写方式将导致JVM在底层处理上有何差异呢......
