Answer:

The delimiter use is "::".

Explanation:

The Java inbuilt String.split( ) function is use to split a String into an array of String.

The split( ) takes delimiter as arguments/parameter which determines at which point the string is to be broken down into different part/token.

From the above code snippet;

Each line in the file a.txt that is not null is splitted using the statement below:

String[ ] v = line.split("::");

The line is splitted using "::" as delimiter and the resulting array is then assigned to the variable 'v'.

For instance, a line in the file could take the form:

John::Smith::Music

When it is splitted,

String lname = John;

because lname make reference to index 0 of the array.

String fname = Smith;

because fname make reference to index 1 of the array.

String dept = Music;

and dept make reference to index 2 of the array.

toThePowerOf is a method that accepts two int arguments and returns the value of the first parameter raised to the power of the
inessss [21]

Answer:

cubeVolume = toThePowerOf(cubeSide, 3)

Explanation:

The function toThePowerOf, receives two int arguments say, a and b, where a is the first argument and b is the second argument as follows:

toThePowerOf(a,b)

The function returns the first argument(a) raised to the power of the second argument (b) i.e a ^ b as follows:

toThePowerOf(a, b){

return a^b

}

In the call to the function, the first argument a, is replaced with the variable cubeSide and the second argument b is replaced with the value 3.

Hence, the returned result becomes cubeSide ^ 3 which is then stored in a variable cubeVolume as follows:

cubeVolume = toThePowerOf(cubeSide, 3)

A function defined beginning with void SetNegativesToZeros(int userValues[], ... should modify userValues such that any negative
Stels [109]

Answer:

   public static void setNegativesToZero(int userValues[]){

       System.out.println("Array before setting negatives to zero "+Arrays.toString(userValues));

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

           if(userValues[i]< 1){

               userValues[i] = 0;

           }

       }

       System.out.println();

       System.out.println("Array After setting negatives to zero "+Arrays.toString(userValues));

   }

Explanation:

Using Java programming Language, the method is created to receive an array of ints as parameter (as specified in the question)

Using a for loop, we iterate over the entire array checking for values that are negative (<0) and setting them to zero.

See a complete program below

import java.util.Arrays;

import java.util.Scanner;

public class num1 {

   public static void main(String[] args) {

   // Create an array and assign values

       int [] arr = {1,2,3,-1,1,2,-4};

   //Calling the method setNegativesToZero

   setNegativesToZero(arr);

   }

//Creating the Method

   public static void setNegativesToZero(int userValues[]){

       System.out.println("Array before setting negatives to zero "+Arrays.toString(userValues));

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

           if(userValues[i]< 1){

               userValues[i] = 0;

           }

       }

       System.out.println();

       System.out.println("Array After setting negatives to zero "+Arrays.toString(userValues));

   }

}
