Using Java from Clojure in plain !@#%^%ing language, with some simple goddamn examples.

java-examples.clj

; Short answer: use import to import a given class
; In java:
;   import java.io.File;
(import java.io.File)

; Preferred: put it in your ns
(ns my-namespace
  (:import java.io.File))

; Instantiate an object with an argument
; 
;   File f = new File("C:/file.txt");
;
(File. "C:/file.txt")

; Use some methods
;
;   File f = new File("C:/file.txt");
;   if(f.exists()){
;     return f.getName();
;   }else{
;     return null;
;   }
;
(let [f (File. "C:/file.txt")]
  (if (.exists f)
    (.getName f)
    nil))

; Use a static method, with arguments
; 
;   File.createTempFile("prefix", "suffix", "C:\Temp");
;
(File/createTempFile "prefix" "suffix" "C:\Temp")
