How do you determine if an array is negative?

Approach:

1. Traverse the elements in the array one by one.
2. For each element, check if the element is less than 0. If it is, then increment the count of negative elements.
3. For each element, check if the element is greater than 0.
4. Print the count of negative and positive elements.

How do you check if all numbers in an array are negative?

Do the linear scan of array. If Yes then calculate z = arrA[i]-x; Make the arrA[z] element as negative. Once the linear scan is done, just check all the elements in arrA[] from 0 to range are negative, if yes them array contains all the numbers of the given range, return true, else false.

How do you remove negative numbers from an array?

Then iterate backward and remove the last indices with the pop method as long as they are negative. The array will be left with is positive values.

How do you find positive numbers in an array?

Can I use a negative integer as the size of array?

No, you cannot use a negative integer as size, the size of an array represents the number of elements in it, –ve number of elements in an array makes no sense.

How to count negative items in array in Java?
