Linux Ubuntu下JDK10的安装与配置方法

1、使用PPA源简单安装配置JDK10

1）安装命令

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install oracle-java10-installer

2）配置JDK10为默认

sudo apt-get install oracle-java10-set-default

3）验证安装

$ java -version
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

2、手动安装配置JDK10

JDK10下载地址：https://jdk.java.net/10/

1）解压下载的文件

tar xzvf openjdk-10_linux-x64_bin.tar.gz

2）移动到系统保存已安装JDK的位置

sudo mv jdk-10 /usr/lib/jvm/java-10-openjdk-amd64/

3）添加新的Java方案

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-10-openjdk-amd64/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-10-openjdk-amd64/bin/javac 1

4）更新系统的java并选择JDK 10

$ sudo update-alternatives --config java
here are 3 choices for the alternative java (providing /usr/bin/java).
  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      auto mode
* 1            /usr/lib/jvm/java-10-openjdk-amd64/bin/java      1         manual mode
  2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
  3            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      manual mode
Press <enter> to keep the current choice[*], or type selection number: 

和

$ sudo update-alternatives --config javac
There are 3 choices for the alternative javac (providing /usr/bin/javac).
  Selection    Path                                          Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-9-openjdk-amd64/bin/javac    1091      auto mode
  1            /usr/lib/jvm/java-10-openjdk-amd64/bin/javac   1         manual mode
  2            /usr/lib/jvm/java-8-openjdk-amd64/bin/javac    1081      manual mode
  3            /usr/lib/jvm/java-9-openjdk-amd64/bin/javac    1091      manual mode
Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/lib/jvm/java-10-openjdk-amd64/bin/javac to provide /usr/bin/javac (javac) in manual mode

5）验证安装

$ java --version
openjdk 10 2018-03-20
OpenJDK Runtime Environment 18.3 (build 10+46)
OpenJDK 64-Bit Server VM 18.3 (build 10+46, mixed mode)

和

$ javac --version
javac 10

3、使用sdkman安装配置JDK10

sdkman安装：https://sdkman.io/install

1）列出所有可用JDK版本

sdk list java
