Question

JAVA PROGRAMMING

Is there a way I can use a method to place a user input variable into an array? Then call the same method to print the array? I'm new to Java programming I'm not sure how to continue. For example:

import java.util.Scanner;

public class PartayScanner {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter pokemon 1:");

String pokemon1 = scan.nextLine();

System.out.println("Enter pokemon 2:");

String pokemon2 = scan.nextLine();

System.out.println("Enter pokemon 3:");

String pokemon3 = scan.nextLine();

System.out.println("Enter pokemon 4:");

String pokemon4 = scan.nextLine();

System.out.println("Enter pokemon 5:");

String pokemon5 = scan.nextLine();

System.out.println("Enter pokemon 6:");

String pokemon6 = scan.nextLine();

System.out.println("Here are your pokemon!");

System.out.println(pokemon1);

System.out.println(pokemon2);

System.out.println(pokemon3);

System.out.println(pokemon4);

System.out.println(pokemon5);

System.out.println(pokemon6);

Hi, you cannot use a single method for once to take value and then to print the values. what you can do is you can do both of these work one after the other in a sequence. Like if you call a method it will ask user to input values and after taking all the values it will print all those values right after input from user. If you want to do both of these separately, you have to create two different methods, one for taking input and one for showing the output. Call them whenever you want.  

import java.util.Scanner;
    public class Test {
            void userIO{
                 int ar[];
                 Scanner scan = new Scanner(System.in);
                 for(int i=0; i<5; i++) {
                     System.out.print("Enter number " + (i+1) + ": ");
                     ar[i] = scan.nextInt();    // Taking user input
                 }
                 for(int i=0; i<5; i++) 
                     System.out.println("Number " + (i+1) + ": " + ar[i]);
            }
            public static void main(String[] args) {
                 userIO();      //Calling the method.
            }
   }

In above example, I have used only one method for both purposes.

Happy Coding.

PLEASE GIVE A THUMBSUP IF IT WAS HELPFULL AND LEAVE A COMMENT FOR ANY QUERY.
