Using Java From DOS Command Line - Cannot Find Or Load Main Class

Nov 10, 2013

When I try to run Java from the Windows DOS command line, I'm running into trouble:
 
1. When I run Java from the wrong directory, I get the error Error: cannot find or load main class myapp1.
 
2. When I get to the "right" directory (.../MyApp1/build/classes/myapp1/, which is where the MyApp1.class file resides), I get the following error:
 
Exception in thread "main" java.lang.NoClassDefFoundError: MyApp1 (wrong name: myapp1/MyApp1)
 
1. The CLASSPATH variable is not set (when I type echo %CLASSPATH% the system returns %CLASSPATH%).

2. I also get the same error above when I use: > java -cp . myapp1

3. I've made sure the PATH is set correctly in environment variables, with the Java path at the beginning of the path string).

Using Eclipse To Maintain Java Application - Could Not Find Main Class Error

Sep 3, 2014

I currently use Eclipse to maintain our Java application. I recently upgraded from Java 6 to Java 7. I updated my Eclipse projects to use the Java 7 .jar files. I can run the application from Eclipse via the Run Configuration.

I can also run the Ant build and it completes successfully. When I install the application on my desktop, I receive the "Java Virtual Machine Launcher: Could not find main class..." error. My CLASSPATH is set to ".".

Toggling Function Behavior Over Time

Jan 6, 2015

I have two classes LightController & Circle. I am trying to create a method to do the following.

1.Grows the diameter of the circle referenced by the receiver's instance variable light, to the argument size.

2. The diameter is incremented in steps of 2, the xPos and yPos are decremented in steps of 1 until the diameter reaches the value given by size.

3. Between each step there is a random colour change. The message delay(anInt) is used to slow down tthe graphical interface, as required.

How can I write the method to do this? I have been fiddling around for ages and just had no luck.

The method is called public void grow(int size) and is in the Light Controller class.

Both classes can be seen below.

import ou.*;
import java.util.*;
/**
* Class LightController
* This class uses the Circle class, and the Shapes window to simulate a disco light, that grows and shrinks and changes colour.
*
*/

public class LightController {
/* instance variables */
private Circle light; // simulates a circular disco light in the Shapes window
private Random randomNumberGenerator;

[Code] ....

Toggling Function Behavior Over Time

Jan 8, 2015

I have two classes LightController & Circle. I am trying to create a method to do the following.

1. Increase the size of the circle by increments of 2 as created in grow()
2. Once it has reached the size specified to then reduce in size in crements of 2 as created in shrink()

I have got the method to increase the size but once it reaches the specified size it then does not shrink.The method is called public void lightCycle(int sizeIncrease) and is in the Light Controller class.Both classes can be seen below.

import ou.*;
import java.util.*;
/**

Find If Number Entered By User Consecutive Or Not

Feb 21, 2014

I need to find if the number entered by the user are consecutive or not!

Ex:this should return a true!! This should return false!

(1,2,3) (3,5,7)
(3,2,4) (1,2,2)
(-10,-8,-9) (7,7,9)

My program seems to work ok when i enter number in order like 1,2,3 = true , and all the numbers for false seem to be working as well! my problem is when i enter number like 3,2,4 that are not in order but still are consecutive!! I thought that another if statement would be the solution but i have tray several different ones and still can't make it work !!!

Java Code:

import java.util.*;
public class Consecutive{
public static void main (String [] args){
Scanner console= new Scanner(System.in);
System.out.println("Enter three numbers");
String numbers = console.nextLine();

[[Code] .....

User To Input 10 Numbers - Find Smallest Element In Array

Dec 2, 2014

I am trying to write a code that asks the user to input ten numbers and then finds and displays the smallest number out of the ones given. I am supposed to implement arrays into the program to do this. But the problem I have run into is that when I compile the code in jgrasp, I am given several error messages and I am not quite sure what I have done wrong. I'm assuming it is either a syntax or a logical error on my part but reading over the code I do not understand what is causing these errors.

This is the most current draft of my code:

import java.util.Scanner;
 public class Exercise7_9 {
public static void main(String[] args) {
double[] numbers = new double[10];
//Enter ten double numbers: Scanner(System.in)
java.util.Scanner input = new java.util.Scanner(System.in);
System.out.println("Please enter ten numbers: ");

[Code] .... 
 
/* Sample Run:
Enter ten numbers: 1.9, 2.5, 3.7, 2, 1.5, 6, 3, 4, 5, 2
*/

And these are the exact error messages:

----jGRASP exec: javac -g Exercise7_9.java
Exercise7_9.java:35: error: '.class' expected
if (double m > list[i]) {
^
Exercise7_9.java:35: error: illegal start of expression
if (double m > list[i]) {

Check For Upper Case Letters From User Input - Cannot Find Symbol Compile Error

Apr 15, 2015

I decided to code this quiz I took in class about asking the user to input a string and the code is suppose to check for upper case letters. If a upper case letter is found, it should increase a count by one. Once the check is done, it should display the number of uppercase letters. For some reason I am getting this weird compile error stating that symbols can't be found...

Java Code:

import java.util.*;
import java.lang.*;
public class StringCheck{
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.println("please enter a string: " );
String s = input.nextLine();

I have permanently set the path of bin of JDK 1.6 in the environment variables of my system. I am able to compile any of my java programs successfully. But when I give command to run the program I am getting an error "could not find or load main class".

When I write the command "set classpath=.;" program runs successfully. I want to know whether I have to set this classpath everytime I run a new progaram. Is there any permanent way to set classpath ?

Error - Could Not Find Or Load Main Class

Sep 30, 2014

I'm trying to run a java program from cmd. I'm using Windows 8, java version "1.8_0_20". I've got two classes, the main class called Middleware and a secondary class, called WorkerThread, of which the main class is using functions. I've successfully compiled both .java files with javac, and created the .class file. So all files are in the same folder. However, when I attempt to run the main class with java Middleware, I get the error message: "Error: Could not find or load main class". Here's the main class:

package middleware;
import java.net.*;
import java.util.concurrent.*;
public class Middleware {
//Number of threads serving clients.
private static int nr_threads = 5;
private static int portNr = 6789;
private static ServerSocket welcomeSocket;
private static ExecutorService executor;

[code]....

My code compiles and runs fine in eclipse but on the console, I'm having troubles.

Altering Parent Method Behavior By Overriding Method It Calls

Apr 21, 2014

I have two classes (Daughter and Son) that contain some very similar method definitions:

public class Family {
public static void main(String[] args) {
Daughter d = new Daughter();
Son s = new Son();
d.speak();
s.speak();

[Code] .....

Each of those classes has a "speak" method with two out of three lines being identical. I could move those into a parent class, but I need each of the child classes to continue to exhibit its unique behavior. I'm trying the approach below, which replaces the unique code with a call to a "placeholder" method that must be implemented by each child class:

public class Family {
public static void main(String[] args) {
Daughter d = new Daughter();
Son s = new Son();

[Code] .....

This works and moves the shared code from two places (the Daughter and Son classes) into one place (the new Mother class, which is now a parent class of Daughter and Son). Something about this feels a bit odd to me, though. It's one thing for a child class to override a parent class's methods to extend or alter their behavior. But, here, I've implemented an abstract method in the parent class to alter what happens when the parent class's method (speak(), in this case) is called, without overriding that parent class method itself.

Error - Could Not Find Or Load Main Class GameTester

Oct 29, 2014

I was trying to write my own version of the game SimpleDotCom from Head First Java. I have two files:

Game.java:
package project_01;

byte hitCount = 0;
String result = "miss";
int counter = 0;
String checkGuess(int[] location,int userGuess){

The two files are in the same directory, "project_01" and the CLASSPATH environment variable is set to ".;".
The game compiled but when I tried launching it with "java GameTester" it returned the error : Could not find or load main class GameTester. I know my game is horrible and probably extremely buggy but I'll fix all the bugs, etc. later, right now I just need to get it to run.
