format method

[swaraj gupta]

Why the output is coming so? Can any one suggest me a concrete rule for such a behavior........

public class Trial
{
  public static void main(String... args) throws Exception 
    {
        System.out.format("Hello world %b" ,"false");   //true
        System.out.format("Hello world %b" ,false);      //false 
        System.out.format("Hello world %b" ,"lse");      // true  
        System.out.format("Hello world %b" ,"True");    //true 
        System.out.format("Hello world %b" ,true);       //true
    }
}

for %b, if the value is boolean value false or null, then the output is false otherwise its true...

With the note that this also applies to the Boolean wrapper class.
