Boolean vs boolean as method parameter

For a method that has a Boolean parameter, as opposed to boolean, is it acceptable to use true or false?

For example, AbstractRenderer.setSeriesVisibleInLegend(Boolean visible):
renderer.setSeriesVisibleInLegend(false);

or would it make a difference in doing:
renderer.setSeriesVisibleInLegend(new Boolean(false));

It will make no difference - if compiler accepts just. "True" or "false" it means it is doing autoboxing - so it would be fine; if it does not accept. Then you haveto use new Boolean(truie)

Yes, it works and compiler doe not complain so it isOK to use true and false in this case:

  public static void takeBoolean(Boolean b){
       
       
    }
   
    public static void main(String[] args) {
       
       
        takeBoolean(true);

}

You see how it works:

public class TestBoolean {
  public static void takeBoolean(Boolean b){

        System.out.println("Class of b:" + b.getClass());

         System.out.println("Vlaue  of b:" + b.booleanValue());


    }

    public static void main(String[] args) {


        takeBoolean(true);

}

}
        

Open in new window


Output:

Class of b:class java.lang.Boolean
Vlaue  of b:true

I think it will work only after Java 5 or 6 - when they introduced autoboxing which deals with those types like Integer, Boolean , Double...

The only difference would be if there is overloading

here we defined two methdos which differe that one tkaes boolean and anothe takse Boolean,
then in thios case it will take the method wchich uses Boolean:


public class testBooolean {

     public static void takeBoolean(boolean b){
                     System.out.println("I type here something else");
     }



    public static void takeBoolean(Boolean b){

        System.out.println("Class of b:" + b.getClass());

         System.out.println("Vlaue  of b:" + b.booleanValue());


    }

    public static void main(String[] args) {


        takeBoolean(new Boolean(true));


}
 
}       

Open in new window


Output:

Class of b:class java.lang.Boolean
Vlaue  of b:true

however in this case:
it wil use method which has argiment of boolean:
(unless you have tw exactly identical methods which only differe by Bollean vs boolens - then you do not care. This is just exotic example

public class TestBoolean{
  public static void takeBoolean(boolean b){
                     System.out.println("I type here something else");
     }



    public static void takeBoolean(Boolean b){

        System.out.println("Class of b:" + b.getClass());

         System.out.println("Vlaue  of b:" + b.booleanValue());


    }

    public static void main(String[] args) {


        takeBoolean(true);
        

}
}

Open in new window


Output

I type here something else
