problem with array

Hello everybody;

I have a problem with array in this static method

we assume we have a 100 books and their titles (I defined an array of object in the main)

and some of them have a same title
so we want to define a method that search first five books that have the title which is entered by user


and i have errors with my code

 public static void findBooks (Book[] findB)//to display the first five books with the same title.
             {
                 Scanner input = new Scanner (System.in);
            int x=0;
            System.out.println("Searching for first five with same title ");
            findB = input..next().charAt(0);
                do{
                
      for (int i=0; i<100; i++){
         
              if (findB[i].getTitle().equals(findB[j].getTitle()) )
                  findB[j].display ();
              x++;
          
              }}while (x<5);
            }
