[Solved] How to create various types of inputs in order to test my algorithm? [closed]

You can use Arrays.sort() to sort your array before feeding it, each of the following describe how to achieve one thing you asked for – try to do each on the array (one at a time) before invoking sort(a)

To sort the array in ascending order:

Arrays.sort(a);

To sort the array in descending order:

Arrays.sort(a,Collections.reverseOrder());

To set constant value to each element in the array:

for (int i = 0; i < a.length; i++) a[i] = 0.25;

To partially sort a list (25% sorted):

Arrays.sort(a,0,a.length/4);

Bonus: to print the array (for debugging purposese usually):

System.out.println(Arrays.toString(a));
