Returning and using booleans

[Reid Hattaway]

I cant believe how much time ive spent trying to use Java's Booleans. In my opinion, C++ was much simpler here. First, what is the difference, if any, between a Boolean and a boolean? Can i even declare (or construct) or A boolean?
What i would like to do is use a test function that test a condition or two and then returns a Boolean(or is it boolean?) indicating whether the test condition was true or false. Here's what I've tried so far.
private Boolean test(some arguments)
{ if(condition)
return new Boolean("True");
//Ive also tried return TRUE and return FALSE
else return new Boolean("False");
//Ive tried return new Boolean(1) and return new Boolean(0)
}
When this functions returns its value I would like to use it in an IF statement. It seems that Java only accepts Booleans (or booleans?) expressions in an IF test conditon.
Do I really need booleans? If i do, whats the correct way to use them here?

A boolean is a primitive that can be initialized to "true" or "false" (without the quote marks). A Boolean is a wrapper object used when you have a boolean and need an object. The two are not the same.

Yes, you really need booleans. Try this.

<font size=+0>private boolean test( some arguments )
{ 
    if ( condition )
    {
        return true ;
    }
    //I've also tried return TRUE and return FALSE
    // [B]These won't work because they are in caps[/B]
    else 
    {
        return false ;
    }
    //Ive tried return new Boolean(1) and return new Boolean(0)
    // [B]booleans and Booleans do not accept integers[/B]
}

or you could simply write this:

<font size=+0>
private boolean test( [I]some arguments[/I] )
{
    return ( [I]condition[/I] );
}

This returns whatever boolean value the condition evaluates to

Definitely better, Junilu. I was trying to stick fairly close to the code he gave so he could see the changes, but I would definitely use yours in real life.
