它是顶部菜单栏左上角的苹果图标。点击后会打开一个下拉菜单。

点击 Java 图标。 它是一个带有蓝色咖啡杯和橙色水汽的图标。点击它将会在一个新窗口中打开“Java控制面板”。
- 如果没有看到Java图标，那就说明还没有安装Java。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/d\/d1\/Check-Java-Version-on-a-Mac-Step-4.jpg\/v4-460px-Check-Java-Version-on-a-Mac-Step-4.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/d\/d1\/Check-Java-Version-on-a-Mac-Step-4.jpg\/v4-728px-Check-Java-Version-on-a-Mac-Step-4.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

4
点击顶部的更新选项卡。 这个界面会显示你的Java版本，以及你是否需要更新Java。
- 如果有可用的更新，按照说明更新到最新推荐的Java版本。你还可以选中“检查自动更新”框，这样在推出新版本时，Java就会始终更新到最新版本。

{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/6\/61\/Check-Java-Version-on-a-Mac-Step-6.jpg\/v4-460px-Check-Java-Version-on-a-Mac-Step-6.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/6\/61\/Check-Java-Version-on-a-Mac-Step-6.jpg\/v4-728px-Check-Java-Version-on-a-Mac-Step-6.jpg","smallWidth":460,"smallHeight":344,"bigWidth":728,"bigHeight":544,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

在Safari中前往 https://www.java.com/en/download/installed.jsp 。在地址栏中输入 https://www.java.com/en/download/installed.jsp ，然后按 ⏎ Return 。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/b\/b0\/Check-Java-Version-on-a-Mac-Step-7.jpg\/v4-460px-Check-Java-Version-on-a-Mac-Step-7.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/b0\/Check-Java-Version-on-a-Mac-Step-7.jpg\/v4-728px-Check-Java-Version-on-a-Mac-Step-7.jpg","smallWidth":460,"smallHeight":346,"bigWidth":728,"bigHeight":547,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

它是页面中央的一个红色按钮。可能会弹出一个窗口，询问你是否希望在此页面上运行Java。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/4\/4c\/Check-Java-Version-on-a-Mac-Step-8.jpg\/v4-460px-Check-Java-Version-on-a-Mac-Step-8.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/4c\/Check-Java-Version-on-a-Mac-Step-8.jpg\/v4-728px-Check-Java-Version-on-a-Mac-Step-8.jpg","smallWidth":460,"smallHeight":344,"bigWidth":728,"bigHeight":544,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

这个网站将检测你正在运行的Java版本，并且如果有需要会建议更新。

这样将打开一个搜索栏，你可以在其中搜索电脑。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/a\/ae\/Check-Java-Version-on-a-Mac-Step-10.jpg\/v4-460px-Check-Java-Version-on-a-Mac-Step-10.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/a\/ae\/Check-Java-Version-on-a-Mac-Step-10.jpg\/v4-728px-Check-Java-Version-on-a-Mac-Step-10.jpg","smallWidth":460,"smallHeight":344,"bigWidth":728,"bigHeight":544,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

输入时，搜索结果将在搜索栏下方筛选出来。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/7\/7d\/Check-Java-Version-on-a-Mac-Step-11.jpg\/v4-460px-Check-Java-Version-on-a-Mac-Step-11.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7d\/Check-Java-Version-on-a-Mac-Step-11.jpg\/v4-728px-Check-Java-Version-on-a-Mac-Step-11.jpg","smallWidth":460,"smallHeight":344,"bigWidth":728,"bigHeight":544,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

它是一个小黑盒子图标，角落里有一个白色的命令提示符。点击后将打开Mac“终端”。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/4\/44\/Check-Java-Version-on-a-Mac-Step-12.jpg\/v4-460px-Check-Java-Version-on-a-Mac-Step-12.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/44\/Check-Java-Version-on-a-Mac-Step-12.jpg\/v4-728px-Check-Java-Version-on-a-Mac-Step-12.jpg","smallWidth":460,"smallHeight":349,"bigWidth":728,"bigHeight":552,"licensing":"<div class=\"mw-parser-output\"><\/div>"}
