// Sample demonstrating calling Java methods like normal

// called like normal script functions.

// Java types used
var Files = Java.type("java.nio.file.Files");
var FileSystems = Java.type("java.nio.file.FileSystems");
var System = Java.type("java.lang.System");

var fs = FileSystems.default;
var bind = Function.prototype.bind;

// Java methods as "functions"

// Java method with bound "this"
var Path = bind.call(fs.getPath, fs);
// Java static method
var Property = System.getProperty;

// call Java static methods and bound instance methods
// like normal script functions.

var root = Path("/");
// print URI for root dir
print(root.toUri());
var home = Path(Property("user.home"));
// list home directory
Files.walk(home).forEach(print);
