Answer 1

You can make all System.out.println in your application not to print anything in console. Create a class like:

import java.io.PrintStream;


public class MyStream extends PrintStream {
   private static final MyStream INSTANCE = new MyStream();

   public static void init() {
      System.setOut(INSTANCE);
   }

   private MyStream() {
      super(System.out);
   }

   @Override
   public void println(Object x) {
      return;
   }

   @Override
   public void println(String x) {
      return;
   }
}

Use it as:

public class Test {

    public static void main(String... args) {
        MyStream.init();
        System.out.println("This line will not print");
    }
}

The will not be printed anymore.
