creating a new line for string

Question

made a program that counts and outputs users based on user input. I want the program to display the names one below the other with the line break but stuck on how to. the code is below:

package uk.ac.reading.cs2ja16.Glen.Stringtest;

import java.util.Arrays;

import java.util.Scanner;



public class stringnames {



    public static String[] countNames (String names) {



        // Create Scanner object

        @SuppressWarnings("resource")

        Scanner names1 =new Scanner(System.in);



        // Read a string

        String read= names1.nextLine();



        // Split string with space

        String numPeople[]=read.trim().split(" ");



        System.out.println("The Number of names inputted is:  "+ numPeople.length);





       return numPeople;

    }   





    public static void main(String[ ] args){



        System.out.println("Enter the amount of names you want(make sure you make space for each name):\n");

        String[] namesout = countNames(null);

        System.out.println(Arrays.toString(namesout));

    }   

}

Answer 1

First of all, the countNames method does not need a parameter, so delete that String names thingy in the method declaration. And delete the word null in your method call.

Now, you can either use a for loop or use one of the methods in the new Stream API if you're using Java 8.

I'll show you both ways.

For loop:

for (String name: namesout) {
    System.out.println(name);
}

the println method automatically adds a new line character at the end of the string that you want to print.

Stream API:

Arrays.stream(namesout).forEach(System.out::println);
