It make the Inter function expand from the correspondence tool to apply the work of the procedure, and this is on breaking to make business enterprise can at tile Inter go forward an alldirections business service and can exchange information in real .The Java language still simplified the construction of the software agent, at not far future, customer can perhaps ill the native puter send ont the software agency to inter, in order to arrive the worldwide locations to search an information for needing or proceeds the limited service. The individual administer financial the assistants is a GUI of simple function to apply the procedure, and expend the proceeding record to the customer39。s usual ine, and is beneficial to the nlanagement of personal finance, and operate easily then. This text totally containing part of two parts, the firsts arc Java summary, from the Java origins, development environment and install with obtaining of development software (JDK) three aspects introduced the 河北經(jīng)貿(mào)大學(xué)畢業(yè)論文 IV Java basic concept, such as: Java history, Java construction, characteristic。 Soft hardware environment, the learning of the JDK and the JDK tool that develop of Java etc. The second is part of to put great emphasis on introduction in the personal administer financial the assistant inside my responsible for models for involving of document piece input, output, add, delete and system line. in a specific way importation that include tile document input, output, add and delete record, use the line and make class can be linearized etc Key Word: Individual Financial Administer, Java, OO 河北經(jīng)貿(mào)大學(xué)畢業(yè)論文 V 目 錄 1 JAVA 概述 ........................................................................................................ 3 JAVA 的起源 .............................................................................................. 3 Java 簡(jiǎn)史 ........................................................................................... 3 Java 的前身： Oak............................................................................. 3 Java 的推出 ....................................................................................... 4 Java 與 Web ....................................................................................... 5 Java 結(jié)構(gòu) ........................................................................................... 6 Java 特性 ........................................................................................... 8 JAVA 開發(fā)環(huán)境 ........................................................................................ 14 Java 開發(fā)的硬件環(huán)境 ..................................................................... 14 Java 開發(fā)的軟件環(huán)境 ..................................................................... 15 獲取和安裝 SUN 公司的 JDK ....................................................... 16 JDK 工具的內(nèi)容 ............................................................................. 17 2 軟件結(jié)構(gòu)設(shè)計(jì) ................................................................................................ 18 軟件的設(shè)計(jì)流程 ..................................................................................... 18 個(gè)人技術(shù)重點(diǎn) ......................................................................................... 19 輸入輸出 ......................................................................................... 19 處理文件 ......................................................................................... 20 添加和刪除 ..................................................................................... 22 線程 ........................................
