Array only printing final element JAVA?

Question

private static String[] nameArray;

public static void newPerson() {
 Scanner scanner = new Scanner(System.in);

 System.out.print("Name: ");
 name = scanner.nextLine();
 nameArray = new String[] {
  name
 };

}

public static void personInfo() {
 System.out.print("Current Persons : \n");
 StringBuilder arrayOutput = new StringBuilder();

 for (String something: nameArray) {
  arrayOutput.append(something);
 }

 String text = arrayOutput.toString();
 System.out.println(text);
}

Hello all thanks in advance for your help I m having a problem I have a loop that call a method once a number is entered in that method is this:

So my question whenever I call the newPerson method and enter a name instead of having all the names stored and in the array and later printed, the personInfo method only prints the final name that I enter in the array why is it not displaying all the names?

You're replacing the nameArray entirely after each input. You have to add it to your array. But it is easier to use 'ArrayList's in this case.

Building on your provided code:

private static ArrayList<String> nameArray = new ArrayList<>();

public static void newPerson() {
       Scanner scanner = new Scanner(System.in); 

       System.out.print("Name: ");
       name = scanner.nextLine(); 
       nameArray.add(name);
}

public static void personInfo() {
    System.out.print("Current Persons : \n"); 
    StringBuilder arrayOutput = new StringBuilder();
    for ( String something  : nameArray) {
        arrayOutput.append(something);
    }  
    String text = arrayOutput.toString();
    System.out.println(text); 
}
