    Default Java array problem

    *newbie java student

    So this is my problem:
    Task: Create a java program with a one-dimensional array (name it as arraySearch), the size of the array will given by the user upon run-time. Your program should also let the user to store elements in the array. Once the array has been populated with elements/values, your program should ask the user to give a number to be searched in the array. Ex: Search the element: 5. If there is an element 5 in your array, display it with its address, if there's none, display "Search Value is Not Found."

    So far i only have done this:
    import java.io.InputStreamReader;
    import java.io.BufferedReader;
    import java.io.IOException;

    public class arraySearch
    {
    public static void main(String args[])throws IOException
    {
    int[] myArray;
    int n,b,c,d,e,copy;

    BufferedReader buffer = new BufferedReader(new InputStreamReader(System.in));

    System.out.print("Please specify the size of array: ");
    n = Integer.parseInt(buffer.readLine());
    copy = n;
    myArray = new int[n];
    System.out.print("Please specify the first element");
    b= Integer.parseInt(buffer.readLine());
    System.out.print("Please specify the second element");
    c= Integer.parseInt(buffer.readLine());
    System.out.print("Please specify the third element");
    d= Integer.parseInt(buffer.readLine());
    System.out.print("Please specify the fourth element");
    e= Integer.parseInt(buffer.readLine());
    int[] myArray= (b,c,d,e);


    }
    }

    Default Re: Java array problem

    Hi tipsydmano, welcome.

    You would be better off using a for loop to accept user input. As it stands you have declared an array of size 'n', asked the user to input four entries and then recreate the array using the four values input by the user.
    Have you tried compiling and running the code because I would expect an error on the last line which should read as follows.

    Java Code:
    int[] myArray = [b]{[/b]b,c,d,e[b]}[/b]
    Regards.
