How To Return Array From A Method / Back Into Main Method That Prints Out Stuff

View Replies View RelatedWriting A Method That Returns Words Without Four Letters Back To Main Method
May 27, 2014I have to write a method called censor that gets an array of strings from the user as an argument and then returns an array of strings that contains all of the original strings in the same order except those with length of 4. For example if cat, dog, moose, lazy, with was entered, then it would return the exact same thing except for the words with and lazy.
Currently, my code so far just prints [Ljava.lang.String;@38cfdf and im stuck.

System.out.println ("How many words would you like to enter?");

Java Method - Return True If String Can Be Found As Element Of Array And False Otherwise
Mar 17, 2014I am new to Java and would like to ask how to do this question specifically:
Code a Java method that accepts a String array and a String. The method should return true if the string can be found as an element of the array and false otherwise. Test your method by calling it from the main method which supplies its two parameters (no user input required). Use an array initialiser list to initialise the array you pass. Test thoroughly.
Overriding In Java - Foo Method Of Class X Is Not Throwing Compile Error
Jul 29, 2013class SubB{
public void foo(){
System.out.println(" x");

super.foo();
if(true) throw new RuntimeException();
System.out.println(" B");
}
public static void main(String [] args){

Why the foo method of class X is not throwing a compile error because according to the override rule, if the superclass method has not declared exception, the subclass method can't declare a new exception...
Main Method Separated From Other Method
Jan 13, 2014Here's a class called Fibonacci
Java Code:
public class Fibonacci {
public static int fib(int n) {
if (n < 2) {return n;}
else {return fib(n-1)+fib(n-2);}
[code]....
it contains one method called fib() and one main method.If I would want to have the main method in another class than fib(), how would I write the two classes? Only cutting the main method from this class to another one doesn't work.My question is, is the reason it doesn't work because I then would have to have a constructor in the Fibonacci class, and create a Fibonacci object first which I then use the method on?

Jan 26, 2014The idea is to create a program to add plants and retrieve plants from a Nursery. I created a class with the properties of the plants and also there is the class an Array list to keep track of the plants entered ( they will have to be printed later) (I am not too sure if adding a public class there is the best option.
The program will allow the user to pick and action and from there the code will do something. I don't want to have all the code inside 'main' The problem is in line 114.This is what I have so far.

Calling A Method To The Main
Sep 10, 2014I have been reading about methods and I do have a beginner level understanding on how they work. I was trying to mess around and make a dog calculator using methods. I ran into a small snag; I cannot get the method to call to the main or the program to compile correctly. The first code below is the original. To me it looks like (based off of some examples I looked at) there should be no problems, but NetBeans gives me a few errors. 1) line 8- "cannot find symbol, variable dogYearCalc; 2) line 18 illegal start of expression; and 3) line 22 - unreachable statement.
import javax.swing.JOptionPane;
public class KrisExample {
public static void main (String[] args) {
double dogYears = 0;
JOptionPane.showInputDialog (null,"Please enter you dog's age in human years:");
[Code] ....
Someone told me that I was calling dogYearCalc without any arguments in your main method. I take that to mean that I needed to add it to the main, so I did here:
public static void main (String[] args, double dogYearCalc) {
That got rid of my first error, but then when I tried to run the program NetBeans said that I have no main class, so switched back to the original program above.
I thought that when I calling the dogYearCalc method on line 10 was the whole purpose of using a method. It seems to me that putting it somewhere in the main is counter productive.

Splitting Up Main Method / Class?
Jan 29, 2014I've written a program just for the sake of it (to learn) and it seem's like theres quite a lot in the main method that perhaps could be split up into seperate classes. I'm not too sure where should start with this though, or what my thought process should have been as I was writing the program.
import java.util.Scanner;
public class Loops {
public static void main(String[] args) {
int answer = 16;
Scanner scan = new Scanner(System.in);
// Question
System.out.println("What is 4 x 4 ?");

here's a version without code comments as they might make it harder to read here -
import java.util.Scanner;
public class Loops {

Scanner scan = new Scanner(System.in);
System.out.println("What is 4 x 4 ?");
