hi hamsa,
first of all: it is usually frowned upon to send text as pictures. so
please copy text as text in the future. the are people with terminal
mail clients or visually impaired using screen readers.
the data in your example is neither valid json value nor a valid json
stream. either you use a json array [{"book":…},{…}] surrounded by
square brackets and missing the trailing comma and unmarshal it into a
[]Book or []*Book. or you use a json stream where multiple json values
follow each other separated usually be a new line and creating a
json.NewDecoder and calling it multiple times to read all books until
you receive a io.EOF error.
have fun and happy holidays

how to unmarshal more than one json object ..
Here is the code
data, err := ioutil.ReadFile("file.txt")
checkError(err)
x:=string(data)
fmt.Println(x)
var b1 book
err1:=json.Unmarshal(data,&b1)
fmt.Printf("Books : %+v", b1)
checkError(err1)
if b1.ID==ID {
log.Printf("The book with ID:%d has title: %s, it was publiched at date:
%s,his author is: %s,it's genre is: %s,it was published by: %s,it's language is:
%s.",b1.ID,b1.Title,b1.PubDate,b1.Author,b1.Genre,b1.Publisher,b1.Language)
}else{
fmt.Println("There is no such book!")
}
that's the output if the file has one object

it doesn't work if there are many objects
