Question

I\'m writing a program which allows the user to input his data then outputs it. Its 3/4 correct but when it arrives at outputting the address it only prints a word lets say

Answer 1

We can easily done using scan.nextLine .It will read the rest of the input till the end. Then assign it to your variable. Entire sentence can be printed easily . Here is the example for your better understanding.

    String s = "HackerRank ";

    Scanner scan = new Scanner(System.in);


    String s2;



    scan.nextLine(); // read the rest of the line of input (newline character after the double token).
    s2 = scan.nextLine();



    /* Concatenate and print the String variables on a new line integer variables on a new line; 

    System.out.println(s + s2);

    scan.close();

} }
