[Debian] Debian上安装java

1.root@VM-12-7-debian:~# apt update

2.root@VM-12-7-debian:~# apt-get install default-jdk ,出现needrestart is being skipped since dpkg has failed 报错，使用

 systemctl restart dpkg-db-backup.命令，重启服务，重新输入 apt-get install default-jdk 命令。

3.安装完成后，通过检查java版本来验证它：

root@VM-12-7-debian:~# java -version
