As the title says. I was attempting to import java.util.random using “import java.util.random;” and got an error message:

Libraries must be installed in a folder named ‘libraries’ inside the sketchbook folder (see the Preferences window).  
The package “java.util.random” does not exist. You might be missing a library.

any help would be greatly appreciated.

It’s capital Random, not random: `import java.util.Random;`  
[Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/util/Random.html](http://Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/util/Random.html)

However, Processing got its own “easier” **random()** function:  
[Processing.org/reference/random\_.html](http://Processing.org/reference/random_.html)
