Question

lets say i input : ‘dog is mammal’

i would like to search for this sentence in a text document. How do i do this in java ?

    System.out.println("Please enter the query  :");
    Scanner scan2 = new Scanner(System.in);
    String word2 = scan2.nextLine();
    String[] array2 = word2.split(" ");

this code snippet accepts the string ‘dog is mammal’ and process each tokens separately.

For example : ‘dog is mammal’

dog

>

>

is

>

>

mammal

>

>

i would like to process the input as

dog is mammal

>

>

I doesnt want it to process it separately. I wanted it to process it as a single string and look for matches. Can anyone let me know where i am lacking ?

Answer 1

If you want to process the String as a single piece of text, why split up the string into words. I would just use the original word2 you have which is the whole text AFAICS

EDIT: If I run

System.out.println("Please enter the query  :");
Scanner scan2 = new Scanner(System.in);
String word2 = scan2.nextLine();
System.out.println(">"+word2+"<");

I get

Please enter the query  :
dog is mammal
>dog is mammal<

The input is not broken up by word.
