Question

I am gettting error saying that I need to initialize variable

but I want to get inputs from the user and want to print them out. (using "for" loop)

public static void main(String[] args)
{
String input;
int i;
  
Scanner sc = new Scanner(System.in);

for (i=1; i < 5; i++) {
System.out.print(i+ ". Please enter a name: ");
input = sc.nextLine();
}
System.out.println("All names are here:" + input);
}
}

Answer 1

import java.util.Scanner;
public class Main
{
   public static void main(String[] args)
   {
       String[] input= new String[5]; //Use a string array and initialize it
   int i;
  
   Scanner sc = new Scanner(System.in);

   for (i=1; i < 5; i++)
   {
       System.out.print(i+ ". Please enter a name: ");
       input[i] = sc.nextLine();
   }
   System.out.println("All names are here:");
   for (i=1; i < 5; i++) //for loop to iterate through the entered values and display one by one
   {
   System.out.println(input[i]);
   }
   }
}
