以下示例显示java.io.ObjectStreamField.getOffset()方法的用法。
package com.jc2182;
import java.io.*;
import java.util.Calendar;
public class ObjectStreamFieldDemo {
public static void main(String[] args) {
// create a new object stream class for Integers
ObjectStreamClass osc = ObjectStreamClass.lookup(Integer.class);
// get the field value from Integer class
ObjectStreamField field = osc.getField("value");
// get the offset of the field
System.out.println("" + field.getOffset());
// create a new object stream class for calendar
ObjectStreamClass osc2 = ObjectStreamClass.lookup(Calendar.class);
// get the field value from Calendar class
ObjectStreamField field2 = osc2.getField("lenient");
// get the offset of the field2
System.out.println("" + field2.getOffset());
}
}
