Sorry to bother again, but I have more problems =|

I have a main class where a method is called:

public static void main(String[] args)
{
int[] array1 = ArrayUtils.randomArray(10, 6) ;
}

And then there is the method being called:

Generates a random array
@param n the size of the array
@param range the random numbers go from 0 to range - 1
^ Instructions given by my teacher, below is what i tried
*/ 
public static int[] randomArray(int n, int range) {
Random arraygen = new Random(); // I guess I'd have to create a random variable...
 
int[] array2 = new int[n]; // So this statement 'should' create a random array everytime its called?? (with value 'n' taken when its called in the tester class)
int ranger = arraygen.nextInt(range-1);
 
for (int i=0;i<=array2.length;i++)  // going thru each value of the array, length was 'n'
{
  array2[i] = arraygen.nextInt(ranger); //Create random value for each array item???
//  System.out.println("Random array value " + i + " is " + array1[i]);  //Random values DO get printed if i uncomment this, but then program crashes afterwards
}

Even if I uncomment the 'system.out.println' line near the end, I do get all the random values but at the end it says:
java.lang.ArrayIndexOutOfBoundsException: 10
at ArrayUtils.randomArray(ArrayUtils.java:48)
at ArrayUtilsTester.main(ArrayUtilsTester.java:9)

Help?

 

 

what if you change

for (int i=0;i<=array2.length;i++)

to

for (int i = 0; i < array2.length; i++)

Does it make sense why this is important?

 

 

Thanks yeah I get it now. If the array length is 5, it already loops through 5 and then it should stop. Was hoping you could help me out with more parts of this exercise. Will post them in 15 mins.

If you fill up your code with System.out.println() statements, you will be able to see for yourself if it generates random values. It will probably also answer many other questions you may have. (eventually, you should learn to use the debugger instead of relying on System.out.println() ).

 

 

Yup, thanks to all i'm done =D

 

 

Would :

1. Using a debugger
2. Using Debugging Sysouts
3. A ponder after forming the correct question to be put in the forum

actually providing a helping hand in solving the issue ?

Thanks.
