First open the terminal, enter/usr/libexec/java_home, see


Note that Java is already installed, now let's configure java_home, because this environment variable is used in many Java-related open source projects, and if it is used temporarily, enter it directly:

Export java_home=$ (/usr/libexec/java_home)
When this terminal is closed it will expire, and to set it to be permanent, we usually do this:

Create and open the ~/.bash_profile file in a TextEdit manner

Touch ~/.bash_profile;open-t ~/.bash_profile

java_home=$ (/usr/libexec/java_home-v 1.7)
Export Java_home
Finally, don't forget if. Bash_profile is just created and needs this sentence to make the configuration effective:

source. bash_profile
Finally cmd+t new window, enter

Echo $JAVA _home

To see if the configuration is global in effect
