GetSystemJavaInfo

Get system java info using Node.js

How to use

S1mple. There's only 2 methods: isJrePresent() and getJreVer()

isJrePresent()

isJrePresent() returns a boolean indicating whether if JRE exists and can found in PATH env.

getJreVer()

getJreVer() returns a list consists of the version information of JRE. An example return value looks like this:

[ '17.0.2', 17, 0, 2 ]

where the first string is the full version number, and the rest are major, minor, and bugfix.

If no JRE found, it will return an array consisting an empty string: [ '' ]

Notes

Note that all of these functions above are synchronized methods. They are wrapped using an async function.

If you prefer in-sync functions, use isJrePresentSync() and getJreVerSync().
