An empty array of Populates the array with a series of integer values between 0 Integers. populate None and 100 (inclusive) that are randomly generated. Sample input/output is given below: Ponulated array: [24, 90, 5, 78, 11, 71, 58, 73, 80, 14]

JAVA Which is true about arrays and methods? A. Arrays cannot be passed to methods B. Passing an array to a method creates a copy of the array within the method C. An array is passed to a method as a reference D. A programmer must make a copy of an array before passing the array to a method

Write a Java method that takes an array of type int and returns a boolean value. The method returns true if the number of positive elements in the parameter array is larger than the number of negative elements. The method returns false if any of the following conditions is satisfied: • The parameter array is of length of 0 or 1 • The number of positive elements of the parameter array is less than or equal to the number of negative elements • The number of positive elements or negative elements is equal to zero The method's header is as follows. public static boolean verify (int[] x) Sample run Result int[] x = (1, 2, 3}; verify(x); {5}; verify(x); int[] x = {1, 2, 3, -5, -1}; boolean b = verify(x); int[] x = new int[0]; verify(x); false boolean b = int[] x = boolean b = false true false boolean b = BIU A Paragraph +v

Write a Java program tat prompts user for a list of integers with 0 as the last value.Save the values in an array. Assume there can be maximum 100 values. Theprogram should have the following methods:- A method that takes the array as parameter and updates each value in thearray to the square of the value.- Another method that takes the original and modified arrays as parametersand displays the original and the squared values.

Write a program named GradeStats.java then implement the following method: public static int[] gradeStats(int[] arr) It accepts int array representing test grades for CISY432 then calculates and returns the following grade statictics: highest, lowest, average, number of grades that are greater than or equal to 70, the number of grades that are less than 70 It returns these five numbers as an int array, and the 1st element is for highest, 2nd for lowest, 3rd for average 4th element for number of grades that are greater than or equal to 70 5th for the number of grades that are less than 70 For example. O Type here to search DELL

In java i have some code for a method that finds the index of an integer that is passed in thet int is (target) the method also has the array called (array) and the first and last element of the array. also for this method to work the array has to be in descending order "static int find(int [] array, int first, int last, int target)" thats the method with all the variables that are passed to it my guess is that the first if statement just will have a short line that is "return -1;" because since the array has to be in descending order the first element cant be greater then the last element in the array but im confused on the rest because i cant find a way to make them one line codes with the conditions that i have to meet in the comments any help would be aprreaciated

Task 2: Write a static method which takes an ArrayList of Strings and an integer and changes the ArrayList destructively to remove all Strings whose length is less than the integer argument. So if the integer argument is 4 and the ArrayList is: tomato cheese chips fruit butter tea buns pie The output tomato cheese chips fruit butter is:

Intellij - Java Write a program which does the following: Create a class with the main() method. Take a string array input from the user in main() method. Note: Do not hardcode the string array in code. After the String array input loop, the array should be: words[] = {"today", "is", "a", "lovely", "spring","day", "not", "too", "hot", "not", "too", "cold"}; Print the contents of this array using Arrays.toString() method. Write a method called handleString() that performs the following: Takes a String[] array as method parameter (similar to main method). Loop through the array passed as parameter, and for each word in the array: If the length of the word is even, get the index of the last letter & print that index. Use length() and indexOf() String object methods. If the string length is odd, get the character at the 1st position in the string & print that letter. Use length() and charAt() String object methods.

Problem: 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

The Delicious class – iterative methods The Delicious class must:• Define a method called setDetails which has the following header: public void setDetails(String name, int price, boolean available) This must find in the ArrayList the Chicken with the given name, change itspricePerKilo to the given price parameter and set whether it is in stock or not. A value of true for the available parameter means the chicken is in stock and a value of false means it is sold out (not in stock). Note that there will only be at most one Chicken object of the given name stored in the ArrayList.• Define a method called removeChicken that takes a single String parameter representing a chicken’s name. This method must remove from the ArrayList the Chicken object (if any) with the given name. The method must return true if a cheese with the given name was found and removed, and false otherwise.The Delicious class – challenge method In the Delicious class complete the findClosestAvailable method: This...
