Java卡電子錢包試驗(yàn)報(bào)告

1、Java卡電子錢包實(shí)驗(yàn)報(bào)告需求分析可以應(yīng)用于現(xiàn)實(shí)中的 Java卡電子錢包需要有電子錢包的安裝、選擇與撤銷選擇、存款、借款、獲取錢包余額以及身份驗(yàn)證。 等功能。定義4條命令，分別為校驗(yàn)PIN加錢、減錢和讀余額。其中，加錢、減錢 和讀余額都是對(duì)錢包余額的操作.PIN的引入增加了錢包應(yīng)用的安全性， Wallet應(yīng) 用要求在進(jìn)行交易（加錢或減錢）之前，必須進(jìn)行PIN校驗(yàn)，只有PIN校驗(yàn)成功后，才能對(duì)余額數(shù)據(jù)進(jìn)行修改。同時(shí)在取消選擇應(yīng)用時(shí)，重載了deselect方法將PIN的校驗(yàn)結(jié)果清空，從而要求在每次選擇應(yīng)用后都需進(jìn)行PIN驗(yàn)證，避免了安全漏洞的產(chǎn)生。系統(tǒng)結(jié)構(gòu)圖安裝public staticvoid
