Print out userinput 1 ,2 ,3 , Array,Java,Eclipse

Question

I'm trying to make a program that asks the user to type in 3 cities and the program is supposed to take the 3 cities , and put them in a String Array , the first city in [0],second in [1] and third in [2] , I got it to ask for them , collect the answers but it's only Printing out the first answer, not all 3. Any ideas how I can fix that?

My code looks like this atm

public static void main(String[] args) {

    String ans;   
    String[] favoritStad = new String [3];
    Scanner scanner1 = new Scanner (System.in);

    System.out.println("skriv in 3 favoritstäder");
    String Användarinlägg1 = scanner1.nextLine();
    String Användarinlägg2 = scanner1.nextLine();
    String Användarinlägg3 = scanner1.nextLine();

    favoritStad[0] = Användarinlägg1;
    favoritStad[1] = Användarinlägg1;
    favoritStad[2] = Användarinlägg1;


    System.out.print(Användarinlägg1);  

}

Användarinlägg is userinputt , favorit stad is favcity the string "ans" was just an idea I tried to make to collect all 3 answers and print it out but never figured it out

Solved it ! Just needed to add

System.out.print(Användarinlägg2);
System.out.print(Användarinlägg3);

A hint: I wouldn't use anything but ASCII for any code. Just causes pain in the --- you know where... — ppeterka

As I suggested in my comment below your question - use a for loop. Also always check twice if you are not using the same variable (for example Användarinlägg1) over and over.

favoritStad[0] = Användarinlägg1;
favoritStad[1] = Användarinlägg2;
favoritStad[2] = Användarinlägg3;

for(int i=0; i<favoritStad.length; i++) {
    System.out.println(favoritStad[i]);
}

In your code you've added the same element 3 times.

You need to use:

favoritStad[0] = Användarinlägg1;
favoritStad[1] = Användarinlägg2;
favoritStad[2] = Användarinlägg3;

And in order to print you can use for loop or just:

System.out.print(favoritStad[0]);
System.out.print(favoritStad[1]);
System.out.print(favoritStad[2]);

You can use for loop to print all the values of an array. You can use something like below:

for (int i=0; i<favoritStad.length();i++){
    System.out.println(favoritStad[i])
}

Try this way

favoritStad[1] = Användarinlägg2;
favoritStad[2] = Användarinlägg3;

Now Print Array:

1st way :

for(int i=0; i<favoritStad.length; i++) {
    System.out.println(favoritStad[i]);
}

2nd way:

 for(String s :favoritStad) {
      System.out.println(s);
  }

Also you need to print...

System.out.print(favoritStad);

instead of

System.out.print(Användarinlägg1);
