Our client just contacted us and said that they are planning from time to time to provide us with four integers instead of two and three. Thinking: What would be a universal/generic solution for dealing with such clients? Should we be proactive and write methods with 5, 6, 7, etc., parameters in advance? Review Multi-Way Conditional Statements, Implement the main method to invoke any of the following methods on demand, test your program with different inputs, and make sure it runs without errors. please use below code in answer and follow structure of example code    public static int sum(int num1, int num2){ return num1 + num2; } public static int sum(int num1, int num2, int num3){ return num1 + num2 + num3; } public static int sum(int num1, int num2, int num3, int num4){ return num1 + num2 + num3 + num4 ; }

I need help with this Java program. I got some minor error that I couldn't fix. Checker Classes You will have to implement specific checks to highlight errors found in the source files. We provided an interface Check.java that defines a single method public Optional<Error> lint(String line, int lineNumber) . All the checkers you write should implement this interface and hence, you need to implement the lint method. All of these should return an an Error when one is present with a custom message of your choosing to describe what the error means to the user. If the condition a Check is looking for is not present for a line, should return Optional.empty(). Other class Error.java public Error(int code, int lineNumber, String message) Constructs an Error given the error code, line number and a message. public String toString() Returns a String representation of the error with the line number, error code and message. The representation should be formatted as (replace curly braces with…

THIS IS MEANT TO BE IN JAVA. What we've learned so far is variables, loops, and we just started learning some array today. The assignment is to get an integer from input, and output that integer squared, ending with newline.  But i've been given some instructions that are kind of confusing to me. Please explain why and please show what the end result is. Here are some extra things i've been told to do with the small amount of code i've already written... Type 2 in the input box, then run the program so I can note that the answer is 4 Type 3 in the input box instead, run, and note the output is 6. Change the output statement to output a newline: System.out.println(userNumSquared);. Type 2 in the input box Change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before). This is what I have so far...   import java.util.Scanner; public class NumSquared {public static void main(String[] args) {Scanner scnr = new…

Still referencing Java, (I hope this is how follow-up questions work, you know my previous question) how could method overloading help reduce errors and are method overloads a top-down or bottom-up approach? Or, is there a difference between top-down and bottom-up in consideration to overloading methods vs writing the actual program?

I am getting an error: findOrCreate()Cannot resolve method findOrCreate in RolePermission.Also, when I try Option 3: The method cannot be reference if it is non-static. I'm not too familiar with it so do you suggest I make it static?

For your final project, you will simply calculate the correct change due after purchase. In our previous assignment, we calculated quarters change in a void function. Here we are doing value returning functions. Do not overcomplicate this. I have provided ample instructions and hints. Plan your mode of attack before you start. If you need assistance, refer first to the hands-on exercise and tutorial you completed on Value Returning Functions in Kotlin in the Methods module. After that, ask me! 1. Create a local double variable called change and set it to a test value (e.g. 44.77) 2. Create five separate functions dollars0, quarters(), dimes(), nickels() and pennies(). 3. Each function will - accept a double amount as an argument - calculate and display that denominations number (e.g. 7 Dollars) - then return the recalculated change (e.g. 0.67) In Kotlin, the function signature for quarters would be: quarters(myChange: Double): Double For this to work, you will need to work from the…

Question 2, please. Returns a pair consisting of the max value in the AD, and of the set of keys that attain that value.

Give a concrete example of a function, where blackbox testing might give the impression that “everything’s OK,” while whitebox testing might uncover an error. Give another concrete example of a function where the opposite is true. You need to support both examples with test cases.
