关于Java中jdk文档的使用问题

本人初学java，最近在学习使用jdk文档，但是对于其中的一些术语不是很懂，求教各位 File[] file = dir.listFiles(); 这条语句我不懂，所以我查了File类的listFiles的方法，但是里面是这样介绍的：“ 返回一个抽象路径名数组，这些路径名表示此抽象路径名表示的目录中的文件” 看了具体的返回值，是File[]类型的，由于我是初学，所以我认为： int [] a = new int[n]这个应该是定义一个数组的方法，要有一个new关键字申请空间去存放，但是这里为什么没有出现new关键字，却能定义成一个数组呢 在下先谢谢各位了

这是jdk文档的截图，左边箭头和右边箭头文字内容之间有什么关系 啊

 这是jdk文档的截图，左边箭头和右边箭头文字内容之间有什么关系 啊 请教下各位大神，jdk文档怎么阅读，

Mac系统下，在哪里可以找到jacob.dll开发包？

在Windows上系统需要用jacob.dll调用本地的word文档，需要把jacob.dll放在JDK的目录下。 但是现在使用的是mac系统，找了半天找不到有Mac系统版本的jacob对应的开发包，请问在哪里可以下载到这个开发包？

java中的X509CertImpl 、X509CertInfo、X500Name这些类怎么在JDK帮助文档里找不到了？

在使用Java程序签发数字证书时，需要用到X509CertImpl 、X509CertInfo、X500Name等类，但这些类好像在JDK 1.6找不到了啊，是怎么回事？

win7系统打开chm显示无法显示网页。

下载了一个jdk1.8的API的chm类型的中文帮助文档，打开之后发现右侧显示无法显示网页。保存chm文件的路径我检查过了，没有中文、#或%。打开chm的属性，里面也没有解除安全锁定的选项。

使用POI导出word文档时，将数据写入输出流报错

Hive执行SQL语句报错hive> show databases; ----已解决

``` hive> show databases; FAILED: SemanticException org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient hive> ``` 百度了很多，都是下面的解决方法 ``` 修改hive的配置文件hive-site.xml <property> <name>datanucleus.schema.autoCreateAll</name> <value>true</value> </property> 然后删除MySQL中原来的表 drop database hive_metastore; 重新初始化元数据 schematool -dbType mysql -initSchema ``` 按照上面的操作执行后，还是报相同的错误 请问，这个如何解决？ 已解决：在多次挣扎后，我尝试了网上很多的方法，但都没有成功；经过多次修改与测试，最终终于找到了问题所在，原来只是java的版本出现的问题，与hive的版本不匹配，我开始使用的是java的最新版jdk-10.0.2,我开始的想法是高版本的能兼容低版本，后来验证我的想法是错的，我将java换成jdk8后，嘿，一下子就可以了，哎，怪我没有好好的认真看一下官方的文档，浪费了我两天的时间啊。

关于java中的String类的方法的问题

新人初学java，今天遇到这样一个问题： 我知道在java中，String是一个字符串类，但是它的一些问题有点疑惑不解 1.定义数据类型 String str; 我知道这是定义了一个str变量 但是却又出现了一个问题； Sting str = new String(c,0,4) // c是数组 我查了下jdk 文档，Sring类当中有很多方法，我知道调用其中的的方法必须要实例化，也就是创建一个对象，但是我不明白就是为什么在声明变量的时候不用new呢，应该也是要分配空间去存放这个变量的呀，这是为什么呢，麻烦各位解答了，在下谢谢各位了

关于java Point2D的小问题

看的Java语言程序设计基础篇第10版 书第9章第6节3中的程序清单9-5中用了Point2D类。在引用时写的是: import javafx.geometry.Point2D 我用的是Eclipse，提示 ``` Multiple markers at this line - The import javafx.geometry.Point2D is never used - Access restriction: The type 'Point2D' is not API (restriction on required library 'D:\java\jdk1.8.0_45\jre\lib\ext \jfxrt.jar') ``` 后来查java的文档Java Platform Standard Edition 8 Documentation，写的是 java.awt.geom.Point2D 这是咋回事？书上写错了吗？

JDK中的UUID无法生成顺序的值

在系统中应用了UUID作为主键值。但是JDK中的UUID生成是random模式，结果就导致那记录在数据库里乱窜。 <br />当然，在大多数情况下，我们并不是让ID有业务逻辑（顺序其实应该算是种逻辑） <br />参考了JDK文档：http://gceclub.sun.com.cn/Java_Docs/html/zh_CN/api/java/util/UUID.html <br /><div class="quote_title">引用</div><div class="quote_div"> <br />version 字段保存描述此 UUID 类型的值。有 4 种不同的基本 UUID 类型：基于时间的 UUID、DCE 安全 UUID、基于名称的 UUID 和随机生成的 UUID。 这些类型的 version 值分别为 1、2、3 和 4。 <br /></div> <br /> <br />但在JDK的UUID中只实现了3和4. <br />是这个是JDK自身没有实现？还是说还有另外的实现类？ <br /> <br />现在需要的是基于Version 1模式的。 <br /> <br />然后我还另外找到两个库已经实现了TimeUUID： <br />http://jug.safehaus.org/Home <br />http://commons.apache.org/sandbox/index.html <br /> <br />不知道各位是否有过类似问题？是选safehaus的吗？

java API文档问题请教大神，哪一个是啊

我下了两个API文件夹javafx-8u72-apidocs和jdk-8u72-docs-all第一个60M第二个380M请问这两个有什么不一样啊，我该看哪一个呢？

JAVA程序的执行入口怎么看？

我用ADT新建了一个工程，默认的有一个叫MainActivity.java的文档： ``` package com.example.m_note0305; import android.support.v7.app.ActionBarActivity; import android.support.v4.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.ViewGroup; public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); if (savedInstanceState == null) { getSupportFragmentManager().beginTransaction() .add(R.id.container, new PlaceholderFragment()).commit(); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } /** * A placeholder fragment containing a simple view. */ public static class PlaceholderFragment extends Fragment { public PlaceholderFragment() { } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_main, container, false); return rootView; } } } ``` 然后我用网上COPY的代码又新建了一个文档SlNotepad.java: ``` package com.example.m_note0305;//把SlNotepad类纳入到m_note0305包内 import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.io.*; import javax.swing.event.*; import java.util.*; import java.awt.datatransfer.*; class text implements Serializable{ /**/ private static final long serialVersionUID = -5303411698842652024L;//序列化版本对象控制 String keyword;//密码 String textmain;//文本部分 } public class SlNotepad extends JFrame implements ActionListener,ListSelectionListener{//公共类名必须和文件名一致 /**/ private static final long serialVersionUID = -1229804758759177927L; //extends表示继承 MenuBar bar;//菜单栏 Menu file,edit,format,help; MenuItem open,dsave,save,newwork,quit,about,fontchoose,colorchoose,backchoose,timeadd,keyopen,keysave,zcancel,copy,paste,cut,delete,selectall,search,autoline; MenuShortcut opencut,dsavecut,savecut,newworkcut,quitcut,aboutcut,fontchoosecut,colorchoosecut,backchoosecut,timeaddcut,keyopencut,keysavecut,zcancelcut,copycut,pastecut,cutcut,deletecut,selectallcut,searchcut,autolinecut; Toolkit tool=this.getToolkit(); Clipboard clip;//剪贴版 Image image=tool.getImage("data/icon.jpg");//框架图标 JTextArea textarea;//文本区域 //此处省略一万字 public static void main(String[] args){ SlNotepad SlNotepad=new SlNotepad("亮亮记事本1.0正式版"); SlNotepad.setVisible(true);//show(); } } ``` 程序跑起来的效果是，就仿佛后面的文档不存在一样。 MainActivity.java里面没有main函数啊，它是怎样开始执行的？ 我不知道怎样把自定义的那个记事本类型用起来，求大神指点~~

一个人独立开发项目有点迷茫，请各位指点迷津

首先呢，请允许我自我介绍一下，小弟工作半年有余，之前在一家公司从事的是JAVA初级程序员的工作，负责一个模块的开发，经济模块，说大也不大，在开发之中偶尔参与了其他模块的编码，后来有余公司的原因（经济纠纷），我不得不离职，现在经朋友介绍来到了另一家公司，说起来大家也别笑，是一个婚介公司规模也蛮大，有十几年的历史，由于几个幕后老板想入IT行业，所以就找我和我的朋友（美工）2个人来试试这行的水，在我看来不管以后的结果或者薪资如何，对我来说都是一个不错的锻炼机会，但是现在就迷茫了，现在接的第一个项目是主要是用于以交友为基础的大型资讯平台，我大致分为了3个模块，会员管理员模块、新闻管理模块和活动模块，因为时间原因准备采取自己比较熟悉的技术Spring2.0+Struts1.2+JDBC(这个是之前公司项目经理所写的一个工具类，很齐全，很方便，用熟了很喜欢)，环境准备使用JDK5+Tomcat5.0+Mysql5.0+。 说了这么多大家也应该有所了解了吧？需求文档我写了一个初始版本，也已经通过了，现在就是想问下大家，接下来我该如何规划我的项目，我该遵循一个什么样的步骤？因为都是我一个人来做，所以没有整个项目开发经验的我，真的是觉得好迷茫，好无助，对于以后功能的细节是否能完成这个我倒不是很担心，比较网上有那么多的前辈和开源代码，我对我自己的实力也比较有信心，只是这整个项目我该的规划我改如何呢？比方说框架搭好后我该从哪一个地方开始下手，设计数据库的步骤，等等，谢谢各位多多指点啊。 这里我还要谢谢我的经理，感谢他给我这次锻炼机会，我一定会努力的完成的！ [b]问题补充：[/b] 这个，找几个朋友来也不是没有想过，我跟经理也有提议，他说你先把这个项目做出来，看效果如何在考虑。（PS：他们的态度完全在于试水），忘了说了，有一个美工和我一起开发，我也就是这个美工介绍过来的，囧。

JAVA 自定义类导入报错的问题。。。。

在学JAVA 用TXT文档编译运行的。先上环境设置，JAVA_HOME: C:\Program Files\Java\jdk1.8.0_60 CLASSPATH:.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar; PATH:%JAVA_HOME%\bin; 我在E盘创建了一个文件夹，取名为com，又创建了1个子文件夹：sly。 一个Person类： package com.sly; public class Person{ private String name; private int age; public void setName(String name){ if(name.length()>6||name.length()<2){ System.out.println("您设置的人名不符合要求"); return; } else{ this.name = name; } } public String getName(){ return this.name; } public void setAge(int age){ if(age>100||age<0){ System.out.println("您输入的年龄不合法"); return; } else{ this.age = age; } } public int getAge(){ return this.age; } } 一个测试类TestPerson: package com.sly; import com.sly.*; public class TestPerson{ public static void main(String[] args){ Person p = new Person(); p.setName = "a"; p.setAge = 20; System.out.println("姓名："+p.getName()+"年龄："+p.getAge()); } } 用cmd编译后，总是报错：Person（）无法找到。 明明导入了Person类 为什么无法找到呢？

JAVA 环境搭建及eclipse问题

各位好， 小的在设置JAVA环境变量时遇到问题，烦请大神看下，谢谢。 我之前下载了一个是JDK，但那时操作应该有些问题，也没设置path，见图1。  eclipse下载后显示的内容见图2.  如果我把之前的文件删除的话显示图3.  我按照网上的方法，设置变量，path等内容，见图4，图5。系统变量%JAVA_HOME%点击浏览文件能正确打开路径，而CLASSPATH打开的却是我的文档（怀疑这地方是否设置有误）。    需求：我想把之前下载的JAVA(TM)删掉，用新下载的JDK,如何操作； 我的CLASSPATH设置的变量值是否有误呢? 在命令行 输入 java -version 及输出一段内容，显示见图片。  path中 的变量值： 

java中的反射的变量定义问题

新人初学，还望各位能多多帮助 我在学习反射的过程中，遇到这样一个问题 String s1 = new String (new StringBuffer("abc")); 这条语句我看了下JDK文档，发现String的构造函数中有一个构造方法的参数是StringBuffer的对象，然后又看了看StringBuffer的定义，发现这条语句等于 String s1 = "abc"; 为什么要这样写呢， 还有 Constructor cs1 = String.class.getConstructor(StringBuffer.class); 这条语句完全看不懂，书上说Class（大写）中存在一个getConstructor这个方法，我也查了下，确实是有的，但是又说了，所以通过String.class(小写)获取关于String类的字节码，我看了下getConstructor的返回值，是一个构造函数，但是具体这条语句是怎么实现的，我还是不懂，求教各位，为什么这个class一会大写，一会小写，‘ 初学，求助，谢谢
