    Default array problem

    Hello everyone, below is my code;

    import java.util.Scanner;
    public class user1{
     
    public static void main(String args[])
    	{
    	Scanner input = new Scanner(System.in);
    	String array[] = new String [15];//array for name only
    	int x;
    	do{
    	//store name
    	System.out.println("Please enter your name below");
    	name(array);
     
    	displayname(array);
    	System.out.println("To exit, press 5; to contiue press any other number");
    	x=input.nextInt();
    	}while(x!=5);
    	{
    	System.out.println("end");
    	}
    	}//end main
     
    	public static void name(String a[])
    	{
    	Scanner input = new Scanner(System.in);
    	int i=0;
    	a[i] = new Scanner (System.in).nextLine();
     
    	i=i+4;
     
    	}//end method
     
     
    	public static void displayname(String g[])
    	{
    	//look here if issues on 2nd user, 3rd etc.
    	int i=0;
    	System.out.print("|"+ g[i]+ "|"); 
    	}
     
    }//end class

    My problem is that when I add a new string name, the previous string name is replaced. I need to somehow increment my int variable' i' inside my static method named 'displayname', however everytime that method is called, 'i' is set to zero...Please help!! Thankyou

    Default Re: array problem

    Define the variable i outside the scope of the method. Several ways to do this: define it as an instance variable, define it as static outside the method so it can be accessed by the static method....
