以下示例显示java.io.ObjectStreamField.compareTo()方法的用法。
package com.jc2182;
import java.io.*;
public class ObjectStreamFieldDemo {
public static void main(String[] args) {
// create a new object stream class for Integers
ObjectStreamClass osc = ObjectStreamClass.lookupAny(Integer.class);
// get the field value from Integer class
ObjectStreamField field = osc.getField("value");
// create a new object stream class for floats
ObjectStreamClass osc2 = ObjectStreamClass.lookupAny(Float.class);
// get the field value from Integer class
ObjectStreamField field2 = osc.getField("value");
// compare with another field
System.out.println("" + field.compareTo(field2));
}
}
让我们编译并运行以上程序,这将产生以下结果-
