2、>本地連接3>屬性中，修改IP、網(wǎng)掩碼）（4）在PC機(jī)的dos命令控制臺ping虛擬機(jī)的IP，確保正常，能ping通（即將虛擬機(jī)內(nèi)外ping通）。（5）配置好虛擬機(jī)下的oracle的數(shù)據(jù)庫和監(jiān)聽。（6）在eclipse中編寫相關(guān)代碼，并用jtable實(shí)現(xiàn)圖形化界面，用以實(shí)現(xiàn)與數(shù)據(jù)庫的連接和操作數(shù)據(jù)庫等功能。（7）在eclipse中導(dǎo)入數(shù)據(jù)庫的驅(qū)動。（8）運(yùn)行eclipse，查看運(yùn)行結(jié)果。2. 核心代碼2.11. 數(shù)據(jù)庫連接package .dbc;import java.sql.Connection;import java.sql.DriverManager
