need help with if statement actions

[KRXB]

hello,

im working on a program that simulates a library, in this library there are 4 classes: llibrary, book, patron, and libraryMain.

In libraryMain, i'm using if statements to allow the user to input text into the menu, choosing different options. When i run the program, it runs through the if statements in order, so i cant enter something like "show patrons" without it executing the "invalid entry" string from the previous case.

i would like the to allow input for every set of cases at the same time without going in order.

String input;
 
        System.out.print("Enter a selection: ");
 
        input = in.nextLine();
 
        // add/remove books control
        if (input.equalsIgnoreCase("add a book"))
        {
            System.out.println("Enter book to add: ");    
        }        
        else if (input.equalsIgnoreCase("remove book"))
        {    
            System.out.println("Enter book to remove: ");
        }
        else
        {
            System.out.println("Invalid Entry");
        }
 
        System.out.print("Enter a selection: ");

I can not see any patron object created in the code. Is it the complete code?
