This might be closer to what you're looking for: import java.text.MessageFormat; import java.util.Scanner; public class Program { public static void main(String[] args) { System.out.println("enter the number of elements to save word in:"); Scanner sc = new Scanner(System.in); int n; n = sc.nextInt(); sc.nextLine(); // remove the remaining return '\n' character from the stream String[] arr = new String[n]; for(int i = 0;i<arr.length;i++) { System.out.println(MessageFormat.format("element number {0}:",i+1)); // i+1 to list starting with 1 instead of 0 arr[i] = sc.nextLine(); // Use nextLine() to get the whole string instead of just up to the 1st space or newline. } int input; input = sc.nextInt() - 1; // Expecting user to input value of element from list above if(input < arr.length && input >= 0) // Add check to make sure negative value isn't input { System.out.println(arr[input]); } else { System.out.println("i did not find this such element"); } } }

lol in my defense it's not blind if the text was different. change ln 11 to: n = reader1.nextInt(); (gotta match var names)
