When I type in echo $JAVA_HOME, I get $JAVA_HOME instead of the location of the jdk. I set the path from the environment variables correctly:
Variable name : JAVA_HOME Variable value: C:\Program Files\Java\jdk1.7.0_25
what am I doing wrong?

Try echo %JAVA_HOME% instead of echo $JAVA_HOME.
The first is for Windows (I'm assuming it's windows based on your filepath), the one you're using is for Linux.
In my case, when I typed "echo $JAVA_HOME" I was getting blank, and I resolved it by following these instructions:
$ vim .bash_profile
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .bash_profile
$ echo $JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home
Reference:
In Ubuntu you may setup and confirm the environment variable like this:
~$ sudo apt install default-jdk
~$ sudo nano /etc/environment
# ADD below line
JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"
~$ source /etc/environment
~$ echo $JAVA_HOME
/usr/lib/jvm/java-11-openjdk-amd64
Above commands are:
- install jdk
- edit environment file
- apply edited environment variable
- show $JAVA_HOME
Linux:
$ vi ~/.bash_profile
export JAVA_HOME=/usr/java/jdk1.5.0_07/bin/java
export PATH=$PATH:/usr/java/jdk1.5.0_07/bin
$ source ~/.bash_profile
Verification:
$ echo $JAVA_HOME
$ echo $PATH
$ which java
