How to communicate with arduino and java in serial port?

I was trying to send a message to Arduino (to test if the Arduino received any message the motor will turn on), the following code works if I run on Terminal

echo 1 > /dev/ttyACM0

But I tried this in Java

Runtime.getRuntime().exec("echo 1 > /dev/ttyACM0");

Anyone knows how to execute in Arduino Serial port?

Java doesn't provide support for serial communications out of the box. You need to use a 3rd party library or extension. Oracle do provide one - Java Communications API

I have used this in the past with AVR Micro-controllers. There are several tutorials on the net to get it up and running.

I used the RXTX lib for Java serial connections.

Very similar code to what worked for me is shown here:
