以往安裝Java SDK跟Android SDK都是在Windows上 突然要在Linux上搞還真是有點讓人不知所措 步驟有點繁雜 後來找到比較簡單的作法 紀錄一下 先使用 yum list java* 查一下目前可用的java opensdk版本 再選擇要安裝的版本 yum install java-1.6.0-openjdk.x86_64 怕麻煩或是沒有版本需求的話也可以直接上最新的 yum install java-latest-openjdk.x86_64 裝完的版本會出現在 /usr/lib/jvm/java-14-openjdk-14.0.2.12-1.rolling.el7.x86_64 (後面看你裝哪版而不同) 然後還要設定全域變數 編輯 /etc/profile 最下方加入 JAVA_HOME變數以安裝的版本為主 export JAVA_HOME=/usr/lib/jvm/java-14-openjdk-14.0.2.12-1.rolling.el7.x86_64 export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export PATH=$PATH:$JAVA_HOME/bin 最後執行生效 source /etc/profile 最後再看版本狀態對不對 java -version

Apple在WWDC發布了最新的作業系統macOS Big Sur之外,也宣布未來Mac將會全採用Apple自家設計的晶片Apple Silicon,因此推出相對應的整合開發環境Xcode 12。Xcode 12會為英特爾x86_64 CPU和Apple Silicon各生成一個二進位檔,並且綑綁一起作為單個應用程式發布
