Mockito / Powermock Private Void Method

Jul 29, 2014

I need to mock a private void method which takes no arguments using mockito and powermock.

The method belongs to a instance which is a spy.

I am working with an old project converting the unit tests from one testing framework to another.

Invoke A Void Method From Another Class?

May 31, 2014

I'm pretty new to Java. I was working the project about gamble. I'm having trouble with invoking the void method from another class. This is what I have done so far.

There are two classes, and I'm trying to invoke gambleAnotherRound method from gambler class into highlighted part in casino class. So, what I want to do is when the program generates "else" part, it goes back into another gamble round.

public class gambler {
public void gambleAnotherRound(double dollarsBet) {
dollarsSpent += dollarsBet;
Random randomNumbers = new Random();
double randomDouble = randomNumbers.nextDouble();

[Code] ....

Below one is casino class.

// use a System.out.print statement to ask how much money each gambler should bet.
// Then declare a variable dollarsBet of type double, and set its value to the keyboard's
// keystroke (be sure to use keyboard.nextDouble()).
// If the user enters 0, then issue a break statement, so that the while loop terminates
// Else, invoke the gambleAnotherRound method of each Gambler, and pass it the variable dollarsBet

[code] ....

Call Void Method For Array

Mar 6, 2014

I am writing a program to take user input in order to create an array, then call a void method that will read in the numbers (from user's input) and fill the array.This method must use a loop to do this.(The array is to be passed to the void method as a parameter)

in theory, this should change the contents of the array, but without returning a result. Because it is a void method, the array is only passed through the method, not returned; Am I correct?How can I return the array and display it without having to change my method type?

Here is my code:

Java Code: package program7array;
import javax.swing.JOptionPane;

public class Program7Array
public static void main(String[] args) { // main method
int howMany = Integer.parseInt(JOptionPane.showInputDialog(null, // user decides how long array is
"How many numbers are there?"));
double [] numbersArray = new double[howMany]; // creating the array
makeArray(numbersArray, howMany); // calling the array

When To And Not To Use Void

Apr 9, 2014

I know void means it doesn't return anything but to me when I think it doesn't return anything it just does equations and other things. So why can you use this? Or is Void like returning input such as a Scanner?

void printStates() {
System.out.println("cadence:" +
cadence + " speed:" +
speed + " gear:" + gear);
}

Using String In A Void Or INT?

Apr 20, 2014

I am trying to make a custom texture system for a block in Minecraft, I am not too advanced with Java and am not sure how to make this work the way I want it to.

Java Code:

/** The list of the types of step blocks. */
public static final String[] blockStepTypes = new String[] {"stone", "sand", "wood", "cobble", "brick", "smoothStoneBrick", "netherBrick", "quartz"};
private Icon missing;
private Icon icon1;
/**
* From the specified side and block metadata retrieves the blocks texture. Args: side, metadata
*/

[code]....

Alright, so basically I figured I could just tell the code to see if the block is made out of Stone, then to set the texture to Stone, or if it's made out of Sand, then set it to Sand.What I usually get is Eclipse telling me to "insert '!= null' check", "insert '!= null' check", and then just error out saying "Opperator != is undefined for the argument type(s) boolean null"

Working Through Printf And Void

Sep 1, 2014

I have a program that I have created from scratch called Product and I also created a Tester program to test my theory. The only problem that I have is that I am getting an error with this statement System.out.printf statement. The statement needs to print out "Program [name = HP ENVY x360 TouchSmart, price = $xxxxxx". The error states that "The method printf(String, Object...) in the PrintStream is not applicable for the arguments (String, String, void).

Which tells me that it is referencing back to the class file where I have

public void applyDiscount(double percent) {
percent = price - (price * percent); //establishing the discount
}

The lines of code in my tester file are (partly displayed)

String formatString = "Product[name = %s, price = %.2f]";
System.out.printf(formatString, product.getName(), product.getPrice())
//user input the discount amount
System.out.println("Enter discount percentage [0 - 100]: %.2f ");
double discount = user_input.nextDouble();
System.out.printf(formatString, product.getName(), product.applyDiscount(discount)); //This is the line giving me an error.
}

I have coded three classes ,1 class containing the Main method. I have declared three private data fields in Staff class and two data fields in Address class.

What Does Static Private Actually Mean

Mar 19, 2015

So I'd like to know what all the statement, not sure if it's the correct way of calling them but I'd like to know what like all of those purple-ish colored words in eclipse actually mean.Here's what I know so far, so if you can add some stuff to it or just correct me:

public - can be accessed by different classes.
private - can't be accessed by different classes.
static - adds a '.' which pretty much lets you like use methods on it? Not really sure about this one.
final - a final value of a variable meaning it couldn't and willn't change?
super - I have no clue, maybe something that has to be executed first? Not sure.
void - bassicly you don't have to use return as it doesn't return any value.
this - Uh-.. I think it has something to do with the class this keyword has been entered into, not quite sure what it does though.

I assume there are alot more but I am just not sure about these common ones, what the actually do and what's their purpose?
