As a part-time student, you took two courses last term. Write a Java program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for each course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less 2.0 and a congratulatory message if the GPA is 3.5 or above.
In fact, I'm not yet past that "Hello World" program.I'm following the steps in "Head First: Java" book, and reached that point where one is ready to write his/her 1st Java code. Here's mine:
public class MyFirstApp { public static void main (String[] args) { System.out.println("I Rule!"); System.out.println("The World!"); }
}
As simple as it should be, and compiles fine producing the correspondent class. But it doesn't run, however, and spits the following execution-time errors:
Exception in thread "main" java.lang.UnsupportedClassVersionError: MyFirstApp : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:643) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:277)
I have two files - I can get the second one to populate with the first ones data and then delete the first one. I cannot get it to then rename itself to the name of the first file. It also only hits the 'rename' section of the code providing I place system.gc in otherwise it completely skips it.
I am having an issue where the code does something very strange when run. Everything seems to be ok in the code but I don't know what is wrong as no error is given.
Here is the code:
import java.util.Scanner; public class Pizza { private static int pizzaSmall = 10; private static int pizzaMedium = 12; private static int pizzaLarge = 14; private static int costPerTopping = 2; /**@return The total cost of the pizza when given the pizza size and the toppings.*/
[Code] ....
And here is the console output:
Please enter the number of Cheese toppings that you would like: 1 Please enter the number of Pepperoni toppings that you would like: 1 Please enter the number of Ham toppings that you would like: 1 Please enter Small for a Small Pizza, Medium for a Meddium Pizza, and Large for a Large Pizza: The number of Cheese toppings is 1. The number of Pepperoni toppings is 1. The number of Ham toppings is 1.
I wish to display a progress bar during a lengthy file translation process. When I created a ProgressBar class to do this and tested it with a short test program, it seemed to work fine. But when I add my ProgressBar class to a package containing various other classes, put that package in a jar file, and then execute the class using the progress bar from a menu in my main program, the frame of the progress bar shows up with the appropriate caption but the JLabel, JProgressBar, and JButton are not displayed. I have gone over my code numerous times and checked that the ProgressBar class constructor is getting the proper arguments.
// package gov.nasa.jpl.ephemeris; import java.awt.*; import java.awt.event.*; import javax.swing.*; /** * Progress bar with message text above the bar and a Cancel button below it */ public class ProgressBar extends JFrame { private boolean _cancelled = false; private JProgressBar _progressBar = null;

I have also been wondering whether I need a separate instance of the border for each panel, or whether I can just create one instance and use it for all three panels.
I have a java program which would display a message dialog box. The problem is it would stopped working before even displaying the message dialog box. This is my code.
import javax.swing.JOptionPane; public class HelloDialog { public static void main(String [] args) { JOptionPane.showMessageDialog(null, "Hello World!"); } }
There is a pop-up window which would say "Java(TM) Platform SE binary has stopped working." I am using textpad. What should I do with this?
I need making the toString() method return a String rather than display a message to the screen. Also, I'm not supposed to call the toString method in my demo class to test it, so what should I do instead?
public class cupDispenser { String location; int noOfCups; cupDispenser(String location,int cups) { this.location=location; this.noOfCups=cups; } public String getlocation()
I'm using Scene Builder 2.0 and have added an ImageView to the parent AnchorPane. I've added my PNG files for the app icon and the various buttons. I select the ImageView in Scene Builder and then crawl the filesystem to the project package folder and select the PNG for the Image. The assigned image is displayed in the Imageview in Scene Builder in both design mode and Preview mode.
While everything else shows up properly when the app is executed, the image assigned to the ImageView does not display.
I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException { int returnVal = fc.showSaveDialog(window); if (returnVal == JFileChooser.APPROVE_OPTION) { StyledDocument doc = (StyledDocument)text.getDocument(); HTMLEditorKit kit = new HTMLEditorKit(); BufferedOutputStream out;
[Code] ....
The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?
I'm trying to make a stock program that stops the user from entering in textfield and displays a message when stock is low. There's just 2 problem the entered value by the user is only decremented twice then the total stock resets for example with SofaTotal and the if statement doesn't work:
I am trying to write a java code for a homework problem in my intro java class but im having problems. This is the problem:
Write a program that open the MyFile.txt and read from a file with these criteria.
1)-The program should display the first five lines of the file’s contents only.
2)-If the file contains less than five lines, it should display the file’s entire content. You must check for end of file and less than 6 lines on the loop iterations.
3)- your program should use loop to read the line by line of the file MyFile.txt.
The serperate myfile.txt has this
I can still remember, at the end of that year, we sat for the last time in our circle together. She played us her favorite song, "like a bridge over troubled water" and quietly passed out a gift she had made for each of us.She had made each of us a pottery heart with our name and the date on it on the back each read "I believe in ME".We all cried including her. She told us she would always remember US. We believed she would.
and this is what the code is suppose to look like after you run it : Java33.png
And this is what i have so far : Java22.png
what needs to go next to complete the javascript to show the first 5 lines of the text files?
I'm currently working on a program that is supposed to translate morse code and then display the result and I'm stuck, my program has tons of errors when I try to compile.
public class Assignment10 { public static void main ( String [] args ) { String str = Input.getString("Please type in a word"); char [] letters = {'a','b','c','d','e','f','g',
I written java code in JSP to display data. I know it is bad practice. Actually my Business-service communicates with DB and returning data in the form of MAP. I don't have beans Because the fields in DB is dynamically changing. So, for now I'm retrieving Data by writing Java code in JSP. Is there any other way to display data without writing java code in JSP?
import java.util.Scanner; public class Magic { public static void main ( String args[] ) { Scanner in = new Scanner (System.in); int[][] square = new int [4][4]; int sqlength = square.length; int magicValue = sqlength * (sqlength * sqlength + 1) / 2;

Here is what the output should look like.
Please enter the 4 values for row 0, separated by spaces: 1 2 3 4 Please enter the 4 values for row 1, separated by spaces: 5 6 7 8 Please enter the 4 values for row 2, separated by spaces: 9 10 11 12 Please enter the 4 values for row 3, separated by spaces: 13 14 15 16
Write a program that will read two numbers and an integer code from the keyboard. The value of the integer code should 1, 2, 3, 4. If the value of the code is 1, compute the sum of the two numbers. If the code is 2, compute the difference (first number minus second). If the code is 3, compute the product of the two numbers. If the code is 4, and the second number is zero, compute the quotient (first divided by second). If the code is not equal to 1,2,3,4, display an error message. The program is then to display two numbers, the integer code and the computed result to the screen
here is the code that I have so far:
public static void main(String[] args) { Scanner read = new Scanner (System.in); int num1, num2, code, sum; System.out.println("Please enter a number"); num1 = read.nextInt();
How i would convert this java code to display using the printf statement, with two decimal places to the right...here is the source code so far, but it has a few errors and needs to be reformated for printf
import java.util.Scanner; // scanner class public class PROB3_CHAL15 { public static void main(String[] args) { double checks =0, totalfee =0, fee = 10, fee1 =.1, fee2 = .08, fee3 = .06, fee4 = .04, checkFee; String input; Scanner keyboard = new Scanner(System.in);
I have been creating a Java program to track inventory using an array. I need to add a search function to it to take a term, input through a text field, and locate a matching instance within the array. How can I code a JButton to grab test input from a JTextField and search for it within the array then display the corresponding information? I also need to add buttons to add and delete items as well.
I have imported several maven projects but I am trying to import a spring project via eclipse and it is not displaying. I did the following file->import->Existing maven projects->browse (found my project)->finish..... The project does not display and I cannot find it. I tired to do it again and the project cannot import because I cannot select it meaning it is already installed.
