I had to make a chart where it took miles 1-10 and convert it to kilometers and then on the other side it needs to show 25-65 (in 5's) kilometers to miles and I dont know how to switch the sides...
import java.util.Scanner;
public class MilesAndKilos {
public static void main(String[] args) {
int miles;
double kilometers=1.60934;
System.out.println(" Miles Kilometers Kilometers Miles");
for(miles=1;miles<10;miles++){
kilometers = miles * 1.60934;
System.out.printf(" %2d %8.3f |
", miles,kilometers);
}
}//end of main method
}
I have this really a graphics program that I'm working on which displays a single die, and right now it is set to the default 6 sides. I need to change it to 12. Here is the program:
My program is supposed to include The three sides of the triangle formatted to two decimal places The perimeter formatted to one decimal place The area formatted to one decimal place The unformatted area. It does run, but it is not decimal formatted. I have read my book to try and figure out how to do this, but it doesn't make since to me.
I had to make a program that allows the user to enter 3 sides and it should output "invalid" if it does not make a triangle and if it does make a triangle it calculates the area of the triangle and it doesnt seem to do anything but say "invalid" as the out put.
import java.util.Scanner; public class MyTriangle { public static void main(String[] args) { Scanner input = new Scanner(System.in); boolean valid = true; double side1, side2, side3, area, A;
Basically the problem is I've been trying to loop my switch (if this is even possible) until the user enters a correct number between 1 and 4. But for some reason when the user enters a correct number (1,2,3,4) the loop runs again. Even when the user enters a wrong number the switch ignores the default and repeats what is in the do.
Am I just trying to loop something that cannot be looped or have I gone?
I needed to make a switch with a string ,but eclipse told met there was an error and that the fix was to switch to 1.7 compliant. I did so and now when i run my program errors come back.
Here are the errors :
Exception in thread "main" java.lang.UnsupportedClassVersionerror: start : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:637) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58)
this is what code i have so far i want to try and get the computer to output a String type result rather than a number and i wonder if there is a way to output the score after the user is done with the game. I couldn't really see if there was a way to incorporate a switch statement.
import java.util.Scanner; import java.util.Random; public class RPSLS { public static void main(String[] args) {
why this switch code does not work for the 'Q'. Everything works fine for the other cases, i.e. 1,2,3, and 'q', but when I type in 'Q', I get the default case. Please note all the values have been defined in an earlier part of the code but for simplicity's sake I have removed them below
do { switch (choix) { //demande le nombre de patons a achete case '1':
I am trying to add a while loop into my switch statement. If you run the program, it will ask to enter the class grade (9,10,11, or 12). If you insert 5, it will say to try again. But, if you enter a wrong number twice, it will continue on to the next part of the program, which is asking how many students are in the class. Therefore, I believe a while loop would work, but it is not working at all. The program still runs, just doesn't fix the error. The program is below:
import java.util.Scanner; public class stephProject { public static void main(String[] args) { //call method welcomeMessage(); //method 1 of 3
I am trying to make GPA calculator. I decided to use only switch statement and make it as simple as possible. The point is to enter as many classes and students as user wants. I keep getting credit points 0 at the end and also text format is not good too. Here is the code.
import java.util.Scanner; import java.io.*; public class SwitchExercise{ public static void main(String[] args) { String grade = ""; String grades=""; String coursename=""; String headingleft="COURSES";
Write an application that reads the quantity for each product until user has completed their order. Your program should use switch, if, for, while and do while statements to read, calculate and display the total retail value of all pro ducts sold for each user transaction. The user should be able to start a new transaction after the first transaction is completed. The user can make no more than 3 total orders
public class Merchandise { private int bootsQTY; private int wranglersQTY; private int hatsQTY; private int chapsQTY;
[Code] ....
When I run my program all of my quantities and the total are 0, I have been stuck for a while trying to figure out how to get values assigned to them...
I am making a programme for a calculator to - Divide, multiply, add and subtract. I have the code written but when I am running it and trying to add it was for some subtracting ....

I have create as short example which contains two classes Cat and Dog followed by a switch statement in the main method.
Class Cat
public class Cat { private String name; //Setter public void setName(String pName) {name = pName;} //Getter public String getName() {return name;} // Constructor public Cat(String catName) {name = catName;}

My Issue is that after creating the objects within the switch statement, is there a way to return the objects back to the main method once created within the switch ?
cannot break from while loop. Whenever I am trying to exit from startCustomerManagement-> backEnd() -> mainScreen()..It gets stuck between mainScreen and backEnd screen. However I can exit from backEnd()->startCustomerManagement() screen

I was making this program and I ran into an issue which is that I cant seem and understand how to get the numbers to go to the other side of the table
I had to make a program that converted 1-9 miles to kilometers and the other side 25-65 (increments of 5) kilometers to miles and thats the part I am having trouble with.
Here is what I have so far
import java.util.Scanner; public class MilesAndKilos { public static void main(String[] args) { int miles; double kilometers=1.60934;
[Code] ....
and this is how I want it to look
MilesKilometersKilometers Miles 1 1.609 | 25 12.430 2 3.219 | 30 15.538 3 4.828 | 35 # here 4 6.437 | 40 # here 5 8.047 | 45 # here 6 9.656 | 50 # here 7 11.265 | 55 # here 8 12.875 | 60 37.290 9 14.484 | 65 40.398
I am new to Java and I am trying to use values that are set for cases in the switch operator.
The first menu ask for you to pick a product and each product has a price on it.
The second menu ask you to pick a state with each state having a decimal value on it.
The third is asking you to put the number of cases and each case is 12 items.
A key note to remember is that each part that a person is choosing is on a different instance!
Here is an example of what i am trying to do.
Menu 1: I picked case 1 that is Computer and it is worth 1000 Menu 2: I picked case 1 that is CT and it's tax is 7.5
Third choice: I picked case 1 and that has 12 items
I want the subtotal witch is: (1000 * 12)
Subtotal in this situation is: 120000
Next i need the total value which is based on what state they picked for the tax percent value picked from the state menu case: (12000 * 0.075 + 120000)
Total value is: 129000
I will post the code I have but based on the choices a person makes will determine the values and I need those values set in the cases to put in a math equation. The problem I am having is retrieving these numbers form the cases inside the menu options and they are on a different instance. So How can I do this in Java code?
Here is the code:
This is menu 1
Java Code:
import java.util.*; //scanners and more class menu{ public void display_menu() { System.out.println ("Please select your product"); //Gives user direction System.out.println ( "1)
What I want to happen is to add 2+ contacts by entering "a" from the menu. Then I want to enter "c" and have it display those contacts. But it doesn't seem to remember that I changed the arrayList masterList.
Java Code:
public class ContactListApp2 { public static void main(String[] args) { boolean quit = false; while (quit == false) { System.out.println("Main Menu:");
int grade = 68; switch (grade) { case 100: System. out.println( "You got an A. Great job!" ); break; case 80: System. out.println( "You got a B. Good work!"); break;
Combining switch statements into if...else decisions? I'm basically trying to teach myself java and am at the point where I have to combine two user inputted values into if...else statements, only I don't really grasp how to do so. (This stuff is soooo addictive.) I'm trying to let the user input the type of residence they have, how many hours they are usually home, and then recommend a pet based on that. I just don't get how to input both selections they make in if...then statements. I get a bunch of errors as soon as I start the if...else part.
import java.util.Scanner; public class PetAdvice { public static void main(String[] args) { int houseType; int hourHome;
