Why do the java methods that sort an array have a void return type?
Step by step
Solved in 2 steps
- Java programming Write a method that takes an array of integers as a parameter. The method should return the occurrence of the even numbers in the passed arrayJAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method. Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2 Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average. If the number of elements in an array is odd don't modify the last number of the array. Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to…Does a method that receives an array as an argument have access to the actual array or only a copy of the array?
- java program Description: Write a method that return the average of an array with the following header: public static double average(double[] array); In the main method, 5 double numbers are required to be entered. Input Example: 1.2 1.2 1.3 1.3 1.35 Output Example: The average value is 1.27Java - Functions with 1D Arrays Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function called maxArray() with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array 3. First line contains the size of the array 4. Succeeding lines are the elements of an array 5. First line contains the size of the array 6. Succeeding lines are the elements of an array 7. First line contains the size of the array 8. Succeeding lines are the elements of an array Output Enter size of array: 5 Enter element 1: 1 Enter element 2: 2 Enter…Pseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiples
- JAVA program Write a Java program that asks the user to enter an array of integers. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (6 - 5) and the fourth gap is 5 (12 - 6). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0.

Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0.Aspects of array that are both positive and negative
- the parameter passing mechanism for an array is call by value or call by reference?What happens when an object such as an array is no longer referenced by a variable?When an array is passed as a parameter to a method, modifying the elements of the array from inside the function will result in a change to those array elements as seen after the method call is complete.
