If Java is installed, right-click the Start menu and select File Explorer. Locate the Java installation directory, which will look something like this (depending on your version): C:\Program Files\Java. If you don’t see a Java installation directory in C:\Program Files, look in C:\Program Files(x86)\Java or C:\Java. Open the folder number containing the most recent version number for JRE or the JDK, e. g. C:\Program Files\Java\jdk17. 0. 4. 1 or C:\Program Files\Java\ jdk1. 8. X_XXX. Highlight the full path to the current folder at the top of File explorer and press Ctrl + C to copy.
