修改java的静态final变量

来源：互联网发布：ps4连接港服网络设置编辑：程序博客网时间：2024/05/19 17:24

请拷贝以下两个类，然后执行

类一：

import java.lang.reflect.*;public class EverythingIsTrue {   static void setFinalStatic(Field field, Object newValue) throws Exception {      field.setAccessible(true);      Field modifiersField = Field.class.getDeclaredField("modifiers");      modifiersField.setAccessible(true);      modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);      field.set(null, newValue);   }       static void setFinalStaticField( Field field, Object newValue) throws Exception {         Field modifiersField = Field.class.getDeclaredField("modifiers");         modifiersField.setAccessible(true);         modifiersField.setInt(field,  field.getModifiers() & ~Modifier.FINAL);         field.set( null , newValue);    }        static void setFinalStaticString( Field field, Object newValue) throws Exception {        Field modifiersField = Field.class.getDeclaredField("modifiers");        modifiersField.setAccessible(true);        modifiersField.setInt(field,  field.getModifiers() & ~Modifier.FINAL);        field.set( null , newValue);    }         public static void main(String args[]) throws Exception {            setFinalStatic(Boolean.class.getField("FALSE"), true);      System.out.format("Everything is %s \n", Boolean.TYPE); // "Everything is true"            setFinalStaticField(TestFinalField.class.getField("finalField") , 99999);      System.out.println("finalField: " + TestFinalField.finalField);            setFinalStaticString(TestFinalField.class.getField("finalString") , "ccccc");      System.out.println("finalField: " + TestFinalField.finalString);         }}

类二：

public class TestFinalField {public static final int finalField = new Integer(1);public static final String finalString = getString();//public static final String finalString = "aaaaa"; 这样赋值修改不了，有办法修改的兄弟请指点，谢谢！public static final Boolean finalBoolean = false;public static void main(String[] args) {// TODO Auto-generated method stub//TestFinalField.finalField = new Integer(1234);}private static  String getString(){String str = new String("aaaaa");//String str = "bbbbb";return str;}}
