I'm having trouble making a code for this problem, my class is working with java in while loops and for loops. Write a method that returns true if an integer parameter n is a perfect number, false otherwise. (recall a perfect number is a number whose sum of its proper factors is equal to itself) (Precondition: n >= 1 .. means you are to presume n is positive) : EXAMPLE: 6 is a perfect number 1 2 3 equals 6...
Please write a Java program: Given an array of positive integers, return a count of the number of even integers. countEvens([2, 3, 5])-1 countEvens([4, 20]) - 2 countEvens([3, 7, 1, 11]) 0 Go Save, Compile, Run (ctrl-enter) int countEvens (int[] nums) {
Please do both parts (in Java); thanks! An Armstrong number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself. For example, 371 is an Armstrong number since 3^3 + 7^3 + 1^3 = 371. Draw the flowchart and write a Java code to find ALL Armstrong number in the range of 0 and 999. You should write your code in two ways: (Yes as if you are...
I need help with these java codingbat questions please: Create a method that creates a user id, where the user id is made up of the first letter of the first name and the entire last name. e.g. john smith ->jsmith getUserld("bill", "gates")-"bgates" getUserId("steve", "jobs")"sjobs" getUserId("larry", "page") -"lpage" Go Save, Compile, Run (ctrl-enter) public String getUserId( String firstName, String lastName) Given a number n, create an array with elements starting from 1 to n. e.g. 5 > getNumArray(1) [1] getNumArray...
java programming. One. Write a method public boolean hasOnlyoddDigits(int n) that returns true if its parameter n contains only odd digits (1, 3, 5, 7, or 9), and returns false otherwise. Zero is counted as an even digit whenever it appears inside the number. Remember that for a positive integer n, the expression (n % 10) gives its last digit, and the expression (n / 10) gives its other digits. Correct answer true false false false 357199 7540573 97531000

1. Please provide a C++ program which faithfully reads a list of non-negative integer scores, ultimately terminating the list reading when the sentinel value (lets use -9999) is entered. The program should then correctly report the number of non-negative scores entered and the arithmetic mean (average) of those scores 2. Demonstrate your programs behavior in response to errors on input (that is, show that it faithfully rejects improper input such as alphabetic characters, decimal points, and commas). Here are some...
write in java 1. Assume the availability of a method named makeLine that can be passed a non-negative integer n and a character c and return a String consisting of n identical characters that are all equal to c. Write a method named printTriangle that receives two integer parameters n and k. If n is negative the method does nothing. If n happens to be an even number, itsvalue is raised to the next odd number (e.g. 4-->5). Then, when k has the value zero, the method prints...

Recursion Exercises These exercises provide practice with recursion in Java. Please add notes if possible. Objectives Module: To write recursive solutions for basic problems that require iteration. To identify and address base cases in a recursive method. Reminders during development Each of your solutions to the problems below should be in their own method. If a method header is provided for a problem, then your solution should have that exact method header. Any changes to the method header will receive...
