    Default can some please help me with this?

    My question is, how can i stop the for loop from executing the else statement every time it cannot find a match for the searchInput? even if the for loop found a match for searchInput the for loop still executes the else statement. how can i deal with this?



    here's my original code:

     
    // The For loop executes the Else statement until a match is found for the if statement, how can i deal with this?
    public void searchBook()
        {
        	String searchInput = JOptionPane.showInputDialog(null, "Enter Search Query: ", "Book Search", JOptionPane.INFORMATION_MESSAGE);
     
        	int x;
     
            try
            {
     
        	for(x=0 ; x<bookName.length ; x++)
        	{ 
        		if(searchInput.equalsIgnoreCase(bookName[x])) 
        		{
        			JOptionPane.showMessageDialog(null, "Book Found !" + "\nTitle: " + bookName[x] + "\nAuthor: " + bookAuthor[x] + 
        				"\nPublisher: " + bookPublisher[x] + "\nBook ISBN: " + bookID[x] , "Book Search", JOptionPane.INFORMATION_MESSAGE);
        		}
     
        		else
        		{
        			JOptionPane.showMessageDialog(null, "BOOK NOT FOUND !" , "Book Search", JOptionPane.ERROR_MESSAGE);
        		}	
        	}
            }
     
            catch(Exception e)
            {
     
            }
     
        }

    thanks in advance...

    Okay, how about you post a question outside of the code block, and post one with better detail.
    If that is your original code, then "how do I deal with it" doesn't make much sense seeing as you're the one who put the else in there.

    2 Simple ways to do it, you can either:
    Remove the else all together, and instead use a boolean variable which is set to true if a match is found, but outside the loop you test if(!matchfound) and put the fail code in there; OR
    Replace else with else if, and test if the current X variable is going to be the last time the loop executes and then print.
