Question
hi, i am writting a java Random Numbers Test, and hystogram,and i wanted to know if someon can help create it?
it need to use these already created variables,There are several methods you need to write. Their headers are given here:
here is what the output should look like for scaled pairs of numbers frequency. This histogram is much easier to view.
Find the maximum value in an array, using static int max( int[] arr ) Compute a random integer in the range [a .. b), using static int randomInteger( int a, int b ) Draw a simple histogram of the array arr., using static void drawHistogram( int[] arr ) Compute num random integers in the range [0 .. range) and put the frequency in arr[]., using static void doSingleTest(int[] arr, int num, int range) Compute num pairs of random integers in the range [0 .. range) and put the frequency in arr[]., using static void doPairsTest(int[] arr, int num, int range)Explanation / Answer
// please check if posible consider my effort
1>
static int max( int[] arr ) {
int maxi=Arr[0];
for(int i=1;i<size;i++)
if(maxi<Arr[i])
maxi=Arr[i];
return maxi;
}
2>
static int randomInteger( int a, int b ) {
Random r = new Random();
int Low = a;
int High = b;
int R = r.nextInt(High-Low) + Low;
return R;
}
