How to connect via SSH in Java and execute 2 commands in a row?

Question

linux

Good afternoon. I am writing a script to connect via ssh to the machine. The tasks are as follows:
1) Connect
2) Execute the transition to the directory and then run the script with the parameters
3) Close the connection
So. Used jsch library. There were exec and shell examples. Exec is not suitable because it executes 1 command, and Shell could do, but these commands must be entered from the keyboard. And I need these commands to be executed by the script. Can you advise how to solve this problem?

Answer 1

command1 && command2

Answer 2

Option 1: execute two commands together
command1 && command2
Option 2: execute cd in the script itself
add cd at the beginning of the script
