Create a Search Button - Java

[scurvyjones]

I need to create a search button for a Mock Library Database.
The Items(books, cds, dvds, and magazines) are in an array list.
If a user inputs "Tom" the search button should return any Items that have the String "Tom" in them.

Any helps would be greatly appreciated.

Thanks

Did you try anything on your problem? How long you are working with Java and related stuff?

As I understand, you need to declare another ArrayList, then loop trough the ArrayList, which contains the items, and on each item call the '.contains(String userInput)', if it returns true, add the item to your new ArrayList.

search the new input in the array list ,

ArrayList ar = new ArrayList();
ar.add( "X" );
ar.add( "Y" );

for( int i = 0; i < ar.size(); i++ )
{
if( ar.get(i) == "X" )
{
System.out.println( "OK" );
}
}
or intead of == you can use if( ar.get(i).equals( "X")) as well

@gayankan, learn to use the code tags for posting code.

or intead of == you can use if( ar.get(i).equals( "X")) as well

No. Unless the objective is to determine whether two references refer to the same object, always use the equals(...) method to determine equality of content.

Incidentally, your code doesn't fulfill the requirement. Which is just as well, as it might otherwise have deprived scurvyjones of a learning opportunity.

I think he want to search all the items containing "Tom".
e.g: "Tomcat", "Tommy",....
If so, you have to crate a method to recognize if the input is a substring of the selected item.
e.g: public boolean recognizeItem( String searchKey, String selectedItem )
{ //method body }

Then you can loop over the array and check if recognizeItem() return true, print out the item.
e.g:

for( int i = 0; i < array.length; i++ ) // assume it is a 1-D array
{
     if recognizeItem( userInput, array[ i ] )
           System.out.println( array[ i ] );
}

Hope it useful :)
