importance of parameter

[payal sharma]

public class Q48
{
static int x = 9;
static int y = 'V';

public static void processInt(int i)
{
System.out.println("process-1");
i = 18;
process(y);
}

public static void process(long l)
{
System.out.println("process-2");
l = 27;
}

public static void process(short s)
{
System.out.println("process-3");
s = 36;
}

public static void main(String[] args)
{
processInt(x);
System.out.println(x);
System.out.println(y);
System.out.println((char)y);
}
}
why process(long l) called instead of process(int i) when passing integer parameters
thanks in advance

Helo!
Int does not fit in short version thus next wider version, long, is chosen since int version is missing.

Hi Payal,
I am confused about your question. You have only two methods named process one takes a long and the other takes a short.
The long method is called because the compiler will automatically widen an int into a long. The compiler will never narrow automatically without complaining loudly.

Hi all:
I think Payal wanted us to think on a different line.In the original version of the problem you are correct to say that process(long) is getting called since the *int y* that is being passed to the process(int) within the processInt(int) method doesnot fit into the process(short) format.
Let us modify the code to the following and then discuss the issue :

<font size=+0><pre>
public class Q48 { 
    static int x = 9; 
    static int y = 'V'; 
    public static void processInt(int i)  { 
        System.out.println("process-1");
        i = 18; 
        process(y); 
    } 
    public static void process(long l) { 
        System.out.println("process-2");
        l = 27; 
    } 
    public static void process(double s) { 
        System.out.println("process-3");
        s = 36; 
    } 
    public static void process(int i) {
        System.out.println("process-4");
        i = 100; 
    }
    public static void main(String[] args)  { 
        processInt(x); 
        System.out.println(x); 
        System.out.println(y);
        System.out.println((char)y); 
    } 
} 
</pre></font>

Which overloaded process() method would be called and why?
Looking forward for the discussion on this.

Hi desai!
So you put the in version of process there which was originally not there.

Thanks all for your prompt reply in my every post-
Yes sandeep is correct I want to ask this issue and I even written the same code with some modification in other post --> refrencing problem.
thanks in advance

Doesn't this method called........
public static void process(int i) {
System.out.println("process-4");
.........
}

Somehow these seems obvious to me.Am I missing something.....

Hi all,
I had replied to a post by Payal in sufficient depth, which eventually went on to discuss the ambiguity errors while compilation.
That should answer why process(int i), is being called in this case.
Let me know if you still have problems.
Hope this helps,
