How To Return Values In Object Return Type Function (method)

Apr 2, 2014

How do i take input values for TwoDPoint (which are objects) and return it back in numerical values also print them.

When i create an object in main method and pass values to my function of return type TwoDPoint,it gives error:- found int,int need TwoDPoiint,TwoDPoint.

// Here is what i tried to do:

Created class TwoDPoint that contains two fields x, y which are of type int. Defined another class TestTwoDPoint, where a main method is defined.In the main method created two TwoDPoint objects.

Then I modified the class TestTwoDPoint and add another function to it. This function takes two TwoDPoints as input and returns the TwoDPoint that is farthest from the point (0,0).

Then I added another function to TestTwoDPoint. This function takes two TwoDPoints as input and returns a new TwoDPoint whose x value is the sum of x values of the input TwoDPoint's and whose y value is the sum of the y values of the input TwoDPoint's.

class TwoDPoint {
int x = 2;
int y = 4;
}
class TestTwoDPoint {
public static void main(String args[]) {
TwoDPoint obj1 = new TwoDPoint();
System.out.println(obj1.x);
System.out.println(obj1.y);

JSF :: Dynamically Adding Components - Object Doesn't Have Such A Property That Is Readable

Jan 12, 2011

In a project I'm ivolved in I have to dynamically add some components. All was going well until I had to generate data tables dynamically. I'm iterating a list of "SomeObject" and when I try to access a property of that object Glassfish tells me that object doesn't have such a property that is readable. I have getters for those properties and SomeObject implements Serializable as well. I used BalusC resources but I'm having no luck.

Equals Method - Take Object Reference And Return True If Given Object Equals This Object

Mar 28, 2014

Create an equals method that takes an object reference and returns true if the given object equals this object.

Hint: You'll need 'instanceof' and cast to a (Geocache)

So far I have:

public boolean equals(Object O){
if(O instanceof Geocache){
Geocache j=(Geocache) O;
if (this.equals(j)) //I know this is wrong... but I can't figure it out
return true;
}

else return false;
}

I think I have it correct up to the casting but I don't understand what I'm suppose to do with the this.equals(). Also I'm getting an error that I'm not returning a boolean... I get this all the time in other problems. I don't get why since I have to instances of returning booleans in this. "returns true if the given object equals this object" makes no sense to me. I assume the given object, in my case, is 'O'. What is 'this' object referring to?

Method Must Return Int Type - If Given Integer Is Strong Return A / If Not Return B

Sep 7, 2014

I want to use a method, which takes for example an int and also returns an integer. For example, if the the given integer is strong return a, if it is notstrong return b. How would you write that in a Code?

I want to use that in a more general way. I want to give a method mlong the value X of the type date and let it return an int. Type date consists of 3 int, one of them is the int month.

mlong should return an int depending on the X.moth. at the moment my code looks like this:

// File1:
public class date {
public int day;
public int month;
public int year;
}

// File 2:
public class monthlength {
public int mlong(date X) {
int t;
t = X.month;
if (t == 1 || t == 3 || t == 5 || t == 7 || t == 8 || t == 10 || t == 12)
{ return 31; }
if(t == 4 || t == 6 || t == 9 || t == 11)
{return 30;}
}
}

Abs - Return New IntClass Object Representing Absolute Value Of Argument

Feb 19, 2014

I don't know how to define "abs." Here are the instructions:
 
The purpose of this exercise is to add to the IntClass class below a method, abs, that takes as its only argument an IntClass object and returns a new IntClass object representing the absolute value of the argument.
 
Define the desired method as a class method.
 
Define the desired method as an instance method.
 
In each case, use the main method to test your code.

There's two boxes of editable code. I'm having trouble with the first one, the one with "abs."

Here is more code:

My code goes here
 
}

Here's another box of code that they want me to fill out:
 
public class MainClass
{
public static void main( String[] args )
{
 
My code goes here...

OOP A Method Being A Return Type In A Method?

May 21, 2015

I stumbled upon a method that im not sure how to handle (yet).Below the code:

public DateTime() {
this.day = day(milliseconds);
this.month = month(milliseconds);
this.year = year(milliseconds);
this.hour = hour(milliseconds);
this.minute = minute(milliseconds);

[code]...

The two last methods stumped me. The return type to each is "DateTime", according to JUnit complaints.I know that I can use the "this" keyword to reference to the object. But how do I get these two methods to return the correct result?

Return Method Involving Arrays

public class School {

public final int MAX_GRADE = 100;
private int [] grades;
public School( int students ) {
grades = new int[students];

[Code] ....

The output is :

The numbers in the array are: 1 2 3 4 6 7 8 9 10 13 14 15
The highest grade is: 11

For some reason it is not giving me the highest number in my array. Did I write the method wrong ? Is my array even passing through HighestGrade ?

Covariant Return In Overridden Method

Mar 5, 2015

For starters here is my code:

Java Code: class A {
int x=5;
}
class B extends A {
int x=6;
}
public class CovariantTest {
public A getObject() {

[Code] ....

And this is the output I get:

sub
5

I am unable to figure out how this is outputting 5 instead of 6. The getObject method of SubCovariantTest is obviously the one being called, and it returns a new B(). So why am I getting class A's x value? I thought since I was getting a B object returned that I would get B's x value.

String Method To Return A Double

Jul 11, 2014

I'm having an issue with figuring out how to structure and call a method using a string prompt. My prof has given us specific methods to create, and the one I'm having issues with is blic static double getOperand(String prompt). What I have currently is this:

public static double getOperand(String operand1, String operand2){
Scanner input = new Scanner(System.in);
System.out.println("What is the first operand?");
operand1 = input.toString();

System.out.println("What is the second operand?");
operand2 = input.toString();
return operand1, operand2;
}

which is obviously not working. When I asked my prof he sent me this, "The String paramater in the getOperand() method is intended to have the prompt value that is passed to it. Within the method, the prompt is then displayed, what the prompt is asking for is input, and then returned to the method call.For example, if the method is public double getOperand(String prompt) within the method you would display the prompt, as in System. out. println(prompt), use the Scanner class to create an object, perhaps called input, and then use the input object to get the value asked for by the prompt. Once you have that value, which in this example would be a double, then return the value to the method that called it.

The call could be something like this: double value = getOperand("What is the first operand?");". But that only works a little. Clearly I'm missing something and no matter what I google, or how many times I read the chapter, I am just not getting this. Everything else up to this point has been easy. and I can create regular methods just fine, the menu method works, but I can't figure out this string method and all the rest build off this method.

Why Recursive Method Continue To Return 0

Nov 13, 2014

I was told to write a method that adds up the sequence of the formula (n/2n+1) eg. 1/3 + 2/5 + 3/7 etc. simple enough i suppose. my method is below

public static double Series(int n){
if (n==0)return 0;
else return (n/(n*2+1)) + Series(n - 1);
}

However for some reason or another it returns 0 for any number that is put in. I've written it dozens of different ways with no change and i feel like something fairly obvious is being missed on my part. I am honestly intrigued and interested as to why this is happening. i assume it has something to do with the way i put the actual formula in cause if i put anything else in like simply n the recursion would work as expected.
