Searching through a text file java

Question

So I am trying to search through a text file and if the user input is found, it returns the entire sentence including white spaces.But apparently I only get the first string and nothing pass the first string in the sentence. For example if i have a text file called "data.txt" and the contents in the first line is " I am a legend". after user enters "I am a legend" the output after the file is searched is "I". Any help would be appreciated.

 public static void Findstr() { // This function searches the text for the    string

    File file = new File("data.txt");

     Scanner kb = new Scanner(System.in);

    System.out.println(" enter the content you looking for");
    String name = kb.next();
    Scanner scanner;
    try {
        scanner = new Scanner(file).useDelimiter( ",");

        while (scanner.hasNext()) {
            final String lineFromFile = scanner.nextLine();
            if (lineFromFile.contains(name)) {
                // a match!
                System.out.println("I found " + name);
                break;
            }
        }
    } catch (IOException e) {
        System.out.println(" cannot write to file " + file.toString());
    }

package com.example;

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class FileSearch {

    public void parseFile(String fileName,String searchStr) throws FileNotFoundException{
        Scanner scan = new Scanner(new File(fileName));
        while(scan.hasNext()){
            String line = scan.nextLine().toLowerCase().toString();
            if(line.contains(searchStr)){
                System.out.println(line);
            }
        }
    }


    public static void main(String[] args) throws FileNotFoundException{
        FileSearch fileSearch = new FileSearch();
        fileSearch.parseFile("src/main/resources/test.txt", "am");
    }

}


test.txt contains:
I am a legend
Hello World
I am Ironman

Output:
i am a legend
i am ironman

The above code does case insensitive search. You should use nextLine() to get the complete line. next() breaks on whitespaces.
