Calling java functions from Clojure -


I can use (.toUpperCase "GOOD") in the closure, because "GOOD" is Java string, and Java UpperCase is the string in the method.

I can also use the java function as a way of calling (java.io.file / separator) from the closure.

But, why do not I (java.lang / object wait3) or (java.lang.system/println "hi")?

  • Can not we use all Java functions from the closure?
  • If not, then there is a rule to call them? If so, where are the references for those tasks?

You can use all Java functions to see the closest page of the closure.

Specifically, you need to get exactly the right words based on sentences, for example the way you are building Java, eg. To execute the println method on the stable member "out" from Java.lang.System: 

  (. Println (system / out) "Hi")
< / Div>

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
