　　为了能够在計算機上开发Java程序和运行Java程序，就需要在Windows操作系统上配置Java开发环境。

　　首先，安裝JDK：

　　1、在Oracle官網上下載JavaSE；

　　2、在Download下載頁面中，選擇Windows平台下的JDK6；

　　3、下载完成后进行安装，默认安装在c：\Program Files\Java下；

　　4、安裝完成後，在DOS命令行狀態下測試JDK6是否安裝成功；

　　5、运行cmd，输入java -version命令，可以查看版本信息，若显示出版本信息，则安装成功。

　　然後進行環境變量的配置：

　　1、修改環境變量是爲了能夠找到JDK安裝目錄下的bin目錄中的Java工具；

　　2、在“我的電腦”->“屬性”->“高級”->“環境變量”->“系統變量”，選擇“新建‘按鈕，添加系統變量；

　　3、新建的系统变量名设置为“JDK”，变量值设置为JDK的安装目录（c：\Program Files\Java\jdk6.0）

　　4、設置PATH變量，在最末尾添加“%JDK%\bin”，在添加值之前先用“;”跟前一個值分開。

　　測試配置好的環境：

　　1、運行cmd，輸入javac命令進行測試；

　　2、若不成功，則提示“‘javac‘不是內部或外部命令”

　　3、若成功，則顯示javac使用幫組提示；

　　用記事本編輯和運行java程序：

　　1、使用記事本編輯一個簡單的HelloWorld程序，文件名必須和類名相同，且區分大小寫；

　　2、在命令行输入 javac HelloWorld.java

　　3、编译成功后，在命令行输入 java HelloWorld,运行程序；

"I acquaint the inhabitants of Liège of this, that they may understand what fate threatens them if they should assume a similar attitude. A raiding party of hostiles had passed near the fort, and had killed, with particular atrocity, a family of settlers. The man and his wife had been tortured to death, the baby had had its brains beaten out against the trunk of a tree, a very young child had been hung by the wrist tendons to two meat hooks on the walls of the ranch-house, and left there to die. One big boy had had his eyelids and lips and nose cut off, and had been staked down to the ground with his remains of a face lying over a red-ant hole. Only two had [Pg 196]managed to escape,—a child of ten, who had carried his tiny sister in his arms, twenty miles of ca?ons and hills, to the post. Every engine of the English Court was put in motion to prevent the Electoral Prince from coming. Oxford had an interview with Schutz, in which he repeated that it was his applying for the writ to the Lord Chancellor instead of to the queen that had done all the mischief; that her Majesty, had it not been for this untoward incident, would have invited the Prince to come over and spend the summer in England—forgetting, as Schutz observed, that the minute before he had assured him that the queen was too much afraid of seeing any of that family here. He advised Schutz—who could not be convinced that he had done anything irregular in his application, quoting numerous proofs to show that it was the accustomed mode of applying for writs—to avoid appearing again at Court; but Schutz, not seeming disposed to follow that advice, immediately received a positive order to the same effect from the queen through another channel. Schutz, therefore, lost no time in returning to Hanover to justify himself. At the same time, Lord Strafford was instructed to write from the Hague, blaming the conduct of Schutz in applying for the writ in the manner he did, as disrespectful to the queen; for, though strictly legal for an absent peer to make such application, the etiquette was that he should defer it till he could do it personally. Strafford ridiculed the idea of any movement being afoot in favour of the Pretender, and observed that, as to sending him out of the Duke of Lorraine's territory, it was not practicable, because the French king maintained that he had fulfilled the treaty, Lorraine not being any part of France. On the other hand, there were striking signs that the cause[17] of Hanover was in the ascendant. Men who watched the course of events decided accordingly. Marlborough, who so lately had been making court to the Pretender, now wrote from Antwerp, urging the House of Hanover to send over the prince without delay to England; that the state of the queen's health made prompt action necessary; and that the presence of the prince in London would secure the succession without risk, without expense, and without war, and was the likeliest measure of inducing France to abandon its design of assisting the Pretender. Shorty had been frantically trying to catch the Deacon's eye, and was making all manner of winks and warning gestures without avail, for the Deacon answered frankly: "Sure you do," Dodd said, and his voice began to rise. He went to the bed, walked along its length to the window, as he talked, never facing Albin. "You know how to make me feel just fine, no worries at all, no complications, just a nice, simple life. With nothing at all in it, Albin. Nothing at all." J. O., I mean it. "Good-bye, my Bluebell, farewell to you, "Cudn't spare one hand to fetch over fifteen—that's a valiant idea. Now d?an't go loitering; fetch out your cattle afore they're roast beef, git out the horses and all the stock—and souse them ricks wot ?un't burning yit." "Do you know my voice?" asked one of Wells's companions. HoME 亚洲春色欧美激情 ENTER NUMBET 0010www.8ox.com.cn
