You can create instance of objects in one of two ways:
(java.awt.Point. 0 1)
;;=> => #object[java.awt.Point 0x3776d535 "java.awt.Point[x=0,y=1]"]
Or
(new java.awt.Point 0 1)
;;=> => #object[java.awt.Point 0x3776d535 "java.awt.Point[x=0,y=1]"]
You can call static methods like this:
(System/currentTimeMillis)
;;=> 1469493415265
Or pass in arguments, like this:
(System/setProperty "foo" "42")
;;=> nil
(System/getProperty "foo")
;;=> "42"
