The elements of an integer-valued array can be set to 0 (i. e., the array can be cleared) recursively as follows: An array of size 0 is already cleared; Otherwise, set the last of the uncleared elements of the array to 0, and clear the rest of the array Write a void method named clear that accepts an integer array, and the number of elements in the array and sets the elements of the array to 0.

The method definition to this question can be given as:

Method definition:

public void clear (int[] arr, int num) / /define method clear.

{

if (num = = 0) / /if block

{

return 0; return value.

}

else / /else block

{

arr[num - 1] = 0; / /assign value in arr.

return arr[]; / /return value.

}

}

clear (arr, num - 1); / /calling

Explanation:

The description of the above method definition as follows:

Firstly we define a method that is "clear" that does not return any value because its return type is "void". This method accepts two integer variables that are "arr[] and num" where arr[] is an array variable and num is an integer variable. Inside a method, we use a conditional statement in if block we check that num variable value is equal to 0. if this condition is true so, it will return 0 otherwise it will go to else block in else block it will assign value in variable arr[num-1] that is "0" and return arr value.
