getSerialVersionUID() method is available in java.io package.
getSerialVersionUID()方法在java.io包中可用。
getSerialVersionUID() method is used to get the serial version UID for this ObjectStreamClass class and the uid defines a set of classes with the same name that has evolved from a common root class and satisfies to be serialized and deserialized during a common format.
getSerialVersionUID()方法用于获取此ObjectStreamClass类的串行版本UID，并且uid定义了一组具有相同名称的类，该类的名称从公共根类演化而来，并满足在通用格式下进行序列化和反序列化的要求。
getSerialVersionUID() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
getSerialVersionUID()方法是一个非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。
getSerialVersionUID() method does not throw an exception at the time of returning serial version UID.
返回串行版本UID时， getSerialVersionUID()方法不会引发异常。

它不接受任何参数。
Return value:
返回值：
The return type of the method is long, it returns the serial version UID of the class defined by this descriptor.
方法的返回类型为long ，它返回此描述符定义的类的序列号UID。
Example:
例：
// Java program to demonstrate the example
// of long getSerialVersion() method of
// ObjectStreamClass
import java.io.*;
import java.util.*;
public class GetSerialVersionUID {
public static void main(String[] args) {
// Instantiates ObjectStreamClass for
// and Calendar
ObjectStreamClass o_stm = ObjectStreamClass.lookup(Calendar.class);
// By using getSerialVersionUID() method is to return
// the serial version uid of this class
long svuid = o_stm.getSerialVersionUID();
// Display svuid
System.out.println("o_stm.getSerialVersionUID(): " + svuid);
}
}
Output
输出量
o_stm.getSerialVersionUID(): -1807547505821590642
