Hello jempot and welcome to the Java Programming Forums!

I hope this example will help you.

Code :

---

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]);  
 }
}

ok i got this one thx...
but you already populate it in the array,... im wondering if the user going to input items in it and save it?...what am i going to use if i continually save an item in array??

Code :

---

import java.io.*;
public class ArrayRead 
{
    public static void main(String[] az)throws IOException
    {
        String s[]=new String[5];
        System.out.println("Enter theStrings");
        BufferedReader b=new BufferedReader(new InputStreamReader(System.in));
        for(int i=0;i<5;i++)
            s[i]=b.readLine();
        for(int i=0;i<5;i++)
            System.out.println(s[i]);
    }
}

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:
