My school gave me a project to create a BlueJ program for an e library. I was running a linear search and although the compiler doesn't show any error, the program doesn't execute after taking the input for "booksearch" (in the excerpt below). Basically, after taking the name of the book taht is to be searched for, no display of present or absent is there. The program abruptly terminates. What to do?

What I have tried:

...
System.out.println("Enter the book to be searched: ");
String booksearch= sc.nextLine();
int j;
for(j=0;j<10;j++)
{
if (booksearch==book[j])
System.out.println("The book is present at " + j);
break;
}
if(j==10)
System.out.println("Book not found");

Solution 1

I see multiple problem in this.
1.

if (booksearch==book[j])

should be

if (booksearch.equals(book[j]))

2. wrong break statement, it should be

if (booksearch==book[j]) {
        System.out.println("The book is present at " + j);
        break;
}

3. don't know how you initialized book array.
