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;}
}
}

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);

[Code] ....

How To Link Compress Method To Return Statement Method GetPText

Set Method Return Type Determined Inside Method

I need to write a method that will consume string representation of Object type and will return one object of this type. How to set return type for the method in this case?

Here is exmaple :

public <?> identifyType(String typeString){
if (typesString.matches("String")){
return new String("");
}else if (typeString.matches("Integer")){
return new Integer(0);
}

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

Mar 2, 2015

public class School {
public final int MIN_GRADE = 0;
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.

Return Int X To Main Method And Print It Out

Oct 10, 2014

I tried to create a simple program. The main method is supposed to call out the secondary method to use Scanner in order to ask a person to type in a number, which will be assigned to int x. Then the secondary method supposed to return the int x to main method, which supposed to print it out. And for some reason I just can't do it. No matter what the main method refusing to accept the int x.

import java.util.Scanner;
public class Return{
static Scanner newNum= new Scanner(System.in);
public static void main(String[] args){
getInt();
System.out.println(x);
}
public static getInt( ) {
// TODO Auto-generated method stub
int x;
System.out.print("give a num");
x= newNum.nextInt();
return x;
}}

Method Should Return A Double That Is Diameter Of Circle

Jul 9, 2014

What's that diameter? Create a new method for the circle class called diameter. Add this method to the circle class described on page 15-1. It should return a double that is the diameter of the circle. No parameters are passed to this method.

In a tester class, test the performance of your new diameter method as follows:

(Your project should have two classes, Tester and Circle.)

here is what i have so far:

public class Circle
{
public Circle (double r)
{
radius = r;
}
public double area()
{
double a = Math.PI * radius * radius;

If Java did not support overloading based on return type, this program should not work, right?

Return Array Data From A Method Back To Main

I believe I have the array correctly reversed within the 'reverseArray' method. I'm trying to send this array back to main, but it appears to contain empty data (a bunch of zeros).

Java Code:

double[] numbers = new double [NUMBER_OF_ELEMENTS];
//Invoke initialize method
initialize(numbers);
