Want to remove debug information

Question

Hello everyone,
I am wondering how to remove debug information (for example, System.out or System.err) automatically when I build/compile a Java project? Does Java compiler or build tool has such options when we build/compile a Java application?
Thanks in advance,
George

Answer 1

The resource you recommended is very helpful. If I
can not use 3rd party libraries in my application,
are there any other approaches to remove debug
information?

GeorgePls be forewarned that this is not perhaps the cleanest way to do it, but it will work.
//begin with writing our own utility that prints to the console
package com.mylogger;
class MyLog
   private final static Printwriter out = new PrintWriter(System.out, true);
   private static boolean shouldPrint;
   static
          //read a property from a config file
          //the property should be set to true for say development
          //and false for say production
          Properties props = new Properties();
          props.load(ClassLoader.getSystemClassLoader ().getResourceAsStream("path to your config file"));
          boolean shouldPrint = Boolean.valueOf(props.get("shouldPrint")).booleanValue();
   public void log(String str)
          if(shouldPrint)
                  out.println(str);
          else
                 //do nothing, no output statements to console
}hope this helps.
