Kick ShellScript on the server from Java

Preface

I got a dump of the table by kicking the ShellScript on the server with an additional function I've never done it in Java, so I'll write it down I used this person as a reference Here, execute the ShellScript of RenumberData.sh in / home / dev / sample / work / sh /
