Display Month Using Enumerated Data Type From String Variable
Apr 1, 2014
I have created an enumerated data type that represents months. In my program I have asked the user for the month. I hold the month entered by user into a string variable. From that string variable I'm trying to display the month using my enumerated data type. I know I can use if statements, but is there another simple way to do it?
import java.util.Scanner;
public class demo {
//Enum class called month that has constants in it representing months
enum month{january,february,march,april,may,june, july,august,september,
october,november, december};
[Code] ....

I've been working on a question using parallel arrays where the user inputs an integer 1-12 and the output will be the name of the month and the number of days in that month. This is what I have so far
import java.util.*;
public class DaysMonth
{
public static void main (String args[]) {
Scanner keyIn = new Scanner(System.in);
int[] days = new int[]{31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
[Code] ....
After I enter the user int it just ends.

I want to be able to use the current date to solve a math problem, specifically as follows:If today is March 17, the math problem of the day should be:
(Month times Day of Month) + 99 = Answer of the Day
(3 x 17) + 99 = 150
How can I create a java script to find the current month and the current day of month, multiple those two together, then add 99 and display the answer as a result.

I'm making a Hangman program for Java, here's my code:
import java.util.Scanner;
public class Hangman {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String answerWord = WordList.getWord();
[Code] .....
The Compiler gives me this only error:
Hangman.java:39: error: unexpected type
displayWord.charAt(i)=userInput.charAt(0);
^
required: variable
found: value
I understand that charAt returns i as a value and not a variable. What do I use to return a variable as I intended?

I've got an abstract class
public abstract class AbstractClass
{
//stuff
}
And a few classes that inherit from it
public class Class1 extends AbstractClass
{
//stuff
}
public class Class2 extends AbstractClass
{
//stuff
}
within another class I have a private variable with the type of the Abstract class, and within one of the methods I assign an object to the the variable like this:
public class Test
{
private AbstractClass temp;
public testMethod(){
Class1 anObject = new Class1();
temp = anObject;
}
}
Is this legal? Will temp become a Class1 object?

I don't understand how i'm supposed to define a variable when the user has to type it into the program so it can be converted. This program i'm working on is supposed to convert from meters to feet (meter = feet * 0.305) but the user has to type in the meters they want converted. how do i solve the problem that keeps coming up that says "variable meter symbol cant be found" ? I keep trying different lines to no avail
public class Lab2
{
public static void main(String[] args) {
double feet = meter * 0.305;
double meter = feet/0.305;
System.out.println("Enter in feet for conversion to meters");
meter = meter * 0.305;

So currently I am trying to use a JTextarea to display text and I then prompt users to type in certain words. I have a few problems that I have encountered. Firstly when I use setText and then if I say setText again after that it erases the previous text that was set. Ideally I want to set text once per line in my whenever a certain task is fulfilled. For example if the text says enter y/n, I want the program to go to the next line once I say y or n. Another problem of course is when I setEditable to true I can edit the whole textArea. I just want to be able to edit the line which I am currently at. Is there anything that I can use that mimics the ACM console program, or even the console down below in most IDE's where everything appears to be done line by line?
Also here is an example of what I am trying to do, along with comments:
Java Code:
console.setText("Math is good!");
console.setText("What is 2+2?: "); //using getText gets the whole line, I want
//everything checked after the colon. That is where the input will be
if(line==4){
console.setText("That is correct");
}
else {
console.setText("That is incorrect");
}
//previous text lines are overriden with new ones. I don't want that, nor do I want to be able to edit the
//whole JtextArea mh_sh_highlight_all('java');
A JtextArea is just not getting the job done.

I am totally new to Java. What is the purpose of this method?
Flow of the int x=3; like where does the 3 go step by step?
Passing Primitive Data Type Arguments (from oracle java tutorials)
Primitive arguments, such as an int or a double, are passed into methods by value. This means that any changes to the values of the parameters exist only within the scope of the method. When the method returns, the parameters are gone and any changes to them are lost. Here is an example:
public class PassPrimitiveByValue {
public static void main(String[] args) {
int x = 3;
// invoke passMethod() with
// x as argument
passMethod(x);
[Code] ....
