Arrays

[BoXxI2004]

in an array how would u create an random array, ask the user to input some number they can be any like 14 , 25 .. and how would u store them?

[wtd]

As array of random numbers, or an array of random length?

[BoXxI2004]

well the user inputs the length he wants... and radom numbers (in a range) are created in the array

so you would just use a forloop to fill in the array

code:

for (int i=0;i<yourArray.length();i++) {      yourArray[i] = //generate random value here }

For the random value, you got to include somethign like .util.Random; and then initialize your randNum class or what not I'm not sure

BoXxI2004-> plz make you avtare smaller, it mess with frame on small rez comps.

Hmmm... not tested:

code:

import java.lang.*; import java.io.*; import java.util.Random; public class Test {    private static int desiredLength;    public static int[] intArrayOfLength(int length)    {       return new int[length];    }    public static void promptForRandomLength(PrintStream output = System.out) throws IOException    {       output.print("Please input a random length: ");    }    public static void readRandomLength(InputStream input = System.in) throws IOException    {       BufferedReader in = new BufferedReader(new InputStreamReader(input));       desiredLength = Integer.parseInt(in.readLine());    }    public static int[] intArrayOfDesiredLength()    {       return intArrayOfLength(desiredLength);    }    public static void populateIntArrayWithRandomValues(int[] arr)    {       Random randNum = new Random(System.currentTimeMillis());       for (int i = 0; i <arr.length; i++)           arr[i] = randNum.nextInt();    }    public static void main(String[] args)    {       int[] myArray;       promptForRandomLength();       readRandomLength();       myArray = intArrayOfDesiredLength();       populateIntArrayWithRandomValues(myArray);    } }
