2014 10 17 補充 :
以下是今天在1台 RAM 4G 的電腦上
使用 Live DVD 安裝 Oracle Java 的過程

作業系統 Linux Mint 17 Qiana Cinnamon 32 bit ( Live DVD )
電腦 RAM 4G

先更新 Mint

sudo apt-get purge openjdk*
( 此步驟為移除系統原先安裝的 openjdk
參考網頁  http://way3sec.blogspot.tw/2012/07/ubuntu-1204-oracle-java-7.html  )

接下來的安裝過程參考以下網頁 :
Oracle (Sun) Java JRE for Ubuntu, Linux Mint and Debian
https://sites.google.com/site/easylinuxtipsproject/java
+
http://www.wikihow.com/Install-Oracle-Java-on-Ubuntu-Linux

到官網下載副檔名為 tgz 的檔案
( Firefox 預設下載到 /home/mint/Downloads 目錄中 )

解壓縮下載的檔案
( 在 Files 這個程式的下拉式選單中就有解壓縮的選項 )
( 解壓縮後 /home/mint/Downloads 多出 jre1.8.0_25 這個目錄 )
( 解壓縮後 從官網下載的檔案就可以刪除了 )

接下來在 Terminal ( 終端機 ) 依序執行以下指令
每個指令會間隔 2 行 方便閱讀
有的指令後會有  -->
代表執行後螢幕出現的文字
或相關的事項

指令如下:


sudo mkdir /usr/local/java


sudo mv /home/mint/Downloads/jre1.8.0_25/ /usr/local/java/jre1.8.0_25/


sudo gedit /etc/profile
-->
在檔案最後加上以下文字
JRE_HOME=/usr/local/java/jre1.8.0_25
PATH=$PATH:$JRE_HOME/bin
export JRE_HOME
export PATH
儲存檔案
關閉檔案
關閉 gedit 這個程式


. /etc/profile


sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jre1.8.0_25/bin/java" 1
-->
螢幕出現以下敘述 :
update-alternatives: using /usr/local/java/jre1.8.0_25/bin/java to provide /usr/bin/java (java) in auto mode


sudo update-alternatives --set java /usr/local/java/jre1.8.0_25/bin/java


java -version
-->
螢幕出現以下敘述 :
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) Server VM (build 25.25-b02, mixed mode)


cd /usr/lib/mozilla/plugins


sudo ln -s /usr/local/java/jre1.8.0_25/lib/i386/libnpjp2.so


sudo killall Xorg
-->
執行此指令前
先把其他所有的程式都關閉
只留下Terminal ( 終端機 )
執行此指令後會重新登入


這樣好像就可以用了
