Is it necessary to set the JAVA_HOME variable every time system is restarted?

I have recently formatted my system and installed Ubuntu 16.0.4 and done all necessary setup for running react-native project.But since then every time i restart the system, getting following error,

ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

I am setting path by using following command,

export JAVA_Home=/home/syamkishore/Downloads/android-studio/jre

If i do so error will be cleared. But if I restart the system again same error occurs.

Can somebody suggest the permanent solution to set the Java path once forever? Thank You.
