What I want to happen is the code under the first comment to to execute if true, or go to the code under the next comments and execute if that statement is true and if that is not true I want the last block of code to execute underneath the last comments.
//Main method public static void main(String args[])throws IOException{ boolean runProgram = true; Scanner keyboard = new Scanner(System.in); //runs program while runProgram is true while (runProgram){
I want to ask a user his name. If he writes John, then program should answer "John is your first name." Is he writes Smith, the program should say "Smith is your last name." If user writes anything else, such as Sue, the program should state "This is not your name."
How to ask user input and also how to work with the nested if-else statement. For some reason I do not understand, my code always results in "This is not your name" even if user writes John or Smith.
import java.util.*; public class NestedIfElse{ public static void main(String args[]) { String name; Scanner reader = new Scanner(System.in); System.out.println("What is your name?");
So from what iv learnt in Java and programming in general is that using a case statement is far more efficient that using multiple IF statements. I have an multiple IF statements contained within a method of my program, and would like to instead use a case statement.
So I want to make a simple Java that ask the user to pick a powers and it has two options.If the user picks magic then execute the first if statement then ask the user again which type of magic the user wants.I can't make it work it keeps printing the else statement. Why is that?
import java.util.Scanner; public class Variable { static Scanner zcan = new Scanner(System.in); public static void main(String[] args)

I have a piece of code for an applet that I want to run as the main applet code, and I want it to loop until a boolean is true, but it needs to paint while the code is looping. Here is the relevant part of my code ....
I have the code and it works very well, but my professor wants us to use Junit testing to test our code. I've never used JUnit before, how it works. Is it possible to have a boolean value (true or false) randomly set?
Here is the code I need to test:
package musicalinstruments; class MusicalInstrument { public String name; public boolean isPlaying; public boolean isTuned; public MusicalInstrument(){ isPlaying = false; isTuned = false;
I am making a program, where the user answers 3 questions and then I add the number of correct answers in to the (int) numberofcorrect variable, then I want to print the results, and no matter how many correct, the program executes first the correct if statement, then the else statement.
Eg: I have 2 correct it will print:
"Grade B, 2 of 3 "
"You failed the test"
Why does it do that? How can I change my code so the else statement dosent print if one of the if statments is allready printed?I want to know how to not execute the else statement, if one of the if statements have allready been executed.Below is my current code for this problem:
if (numberofcorrect == 3){ System.out.println("Grade A, full score");} if (numberofcorrect == 2){ System.out.println("Grade B, 2 of 3 ");} if (numberofcorrect ==1) { System.out.println("Grade C, 1 of 3");} else { System.out.println("You failed the test"); }
So, I don't know how to start off this program. I'm not looking for the final answer, but I don't know two things: 1. the objective, 2. what type of thing do I start it off with? A method? I'm pretty sure it's not a class right because it already has a class?
public class WebFarm { private ArrayList<Server> servers; /* constructors and other methods and instance variables not shown */ } public class Server
[Code] ....
the Instructions:
The ping() method of the Server class returns true if the server is currently functioning normally; otherwise it returns false. Write a definition for the needsAttention() method of WebFarm that returns an ArrayList containing the servers that are not functioning normally:
public ArrayList<Server> needsAttention() { //I can put code here }
Create an application that generates a quiz. Prompt for the user's first and last name, college major, and confidence in test taking (high, medium, or low). The quiz should contain at least five true/false questions about horticulture. When the user selects the correct answer, a message of positive reinforcement should be displayed. If the user selects the incorrect answer, the correct answer should be displayed with a message of constructive criticism. At the end of the quiz, display the number of correct and incorrect answers as well as the percentage of correct responses for each user.
import java.util.Scanner; class HorticultureQuiz { public static void main(String[] args){
I'm supposed to take this truth table and alter it so it displays 1's and 0's instead of true false. I'm assumed to do this I would just need to change the variable type and replace true and false with 1 and 0 but every way I try this does not work.
//a truth table for the logical operators.
class LogicalOpTable { public static void main(String args[]) { boolean p, q; System.out.println("P Q AND OR XOR NOT"); p = true; q = true; System.out.print(p + " " + q +" ");
I want to execute my jsp code to compare two dates after every 10 seconds if user enter date and current sys date are equal it will send the mail to the user automatically. Below is my jsp code
this if condition i want to check the date after every 10 seconds and when two dates are equal it will send the mail using below mail code
if(ExpcReDt.compareTo(dateStr)>0) { out.println("Expected return date is greater than current date"); } else if(ExpcReDt.compareTo(dateStr)==0)
I'm trying to create a program that has two labels... one in the top left and one in the top right... so far when i run it only the one in the top right (label2) shows... also In the program there will be multiple button and when I click a button it will show a different panel and then i can go back to the first panel to select other panels... so far i haven't figured out how to make panels visibility go false/true with actionlistener. last thing... when i have more then one panel added to the frame none of them show up.
Java Code:
//Matthew import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Test{ public static void main(String[] args){
Assignment: Given an array of scores sorted in increasing order, return true if the array contains 3 adjacent scores that differ from each other by at most 2, such as with {3, 4, 5} or {3, 5, 5}.
public boolean scoresClump(int[] scores) { for (int i = 0; i < scores.length; i++) { int a = scores[i]; int b = scores[i + 1]; int c = scores[i + 2]; if (Math.abs(b-a) + Math.abs (c-b) <=2) return true; } return false; }
I got it right for some of the input, but not one of them. I tried to use the for loop and if statement on a specific input that I got wrong:
I suspect it has something to do with the for loop, but I don't see the problem with it. It should work, shouldn't it? But anyway, here is the error for {4,5,8} :
import java.util.Scanner; public class AdditionQuiz { public static void main (String[] args){
//Generate random two integers using utility System.currentTimeMillis int n1 = (int)(System.currentTimeMillis() % 10); int n2 = (int)(System.currentTimeMillis() / 7 % 10);
[Code] ....
however the true/false result can not be printed due to the "answer" variable...
public class Main { private static void foo(Integer a) { System.out.println("Integer"); } private static void foo(long a) { System.out.println("long");
[Code] ....
This code prints long. Why is that? How did compiler decided that it likes long version of foo() method the most. If I had to guess I'd pick int... or possibly Integer as they are most similiar to what was passed. But why long?
I am unable to run this java mail code, whats the error!!
public class Class1 { final String senderEmailID = "from@gmail.com"; final String senderPassword = "password"; final String emailSMTPserver = "smtp.gmail.com"; final String emailServerPort = "465"; String receiverEmailID = null;
[Code] ...
I get an error as this
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1 at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1949) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:654) at javax.mail.Service.connect(Service.java:317)
