    Default Re: How to input items in array

    Hello jempot and welcome to the Java Programming Forums!

    I hope this example will help you.

    public class Jempot {
     
     public static void main(String[] args) {
     
      //Declare a String Array which can hold 5 items. 
      String[] myArray = new String[5];
     
      //Populate the Array
      myArray[0] = "John";
      myArray[1] = "Rosie";
      myArray[2] = "Mark";
      myArray[3] = "Steve";
      myArray[4] = "Natalie";
     
      //Loop through the Array and print its content.
      for(int a = 0; a < myArray.length; a++){
       System.out.println(myArray[a]);
      }
     
      //Print just one Array value
      System.out.println("\n" + "myArray[2] value is: " + myArray[2]);  
     }
    }

    Take a look at vigneswaras example. Good work.

    He is using a buffered reader to take user input from the console.

    This can also be done using the Scanner class. Here is an example:
