- when an individual array element of an array of type int is passed to a method, it is passed by reference. True FalseJava: Write a complete method to create an array of random integers. Method Specification The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between the lower and upper bound., using these rules: The lower bound is always inclusive. If the boolean parameter is true, the upper bound is also inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). If any of the parameters are invalid, null is returned. Driver/Tester Program I have provided you with a driver/tester program that you can use to test your code before submitting. Paste your code into the placeholder at the top of the file. I strongly recommend running this program before you submit your homework.

- 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 numMultiplesIn java when an array is passed to a method, what does the method receive? A. The reference of the array B. A copy of the array C. Length of the array D. Copy of first elementProblem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false
- A bit new to methods and need a little bit of help. Swap Method Your task is to write a public static method named swap that takes a single parameter which is an array of doubles. This method should swap the first and last element in the array and then return the adjusted double array. You can assume that all arrays passed into the method are a length of 2 or more. For example, the test data provided when passed into the swap method should go from: {8.34, 7.221, 10.643, 93.2} toQuestion: 1. Write a method that has an int parameters. Creates an array of integers of that size. Reads in values for the array from the user. Returns the newly created array. 2 Write a method that given an array of integers.returns the index of the smallest integer.Write a method that returns the index of the smallest element in an array of doubles. The method should receive an array for formal parameters.
