Option 1:-

Running the following command in the command prompt will return the Java Version Installed, If Java is not installed then it would return “Unknown Command” error message.

Code (fw): Select all Collapse

java -version

For eg.
If it is installed then the above command would return

Code (fw): Select all Collapse

java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b18)
Java HotSpot(TM) Client VM (build 25.66.-b18, mixed mode, sharing)

You may capture the output programmatically and then decide.

Option 2:-
You can also read the registry value to verify the Java installation

32 bit
"HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion"

64 bit
"HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment\CurrentVersion"
