Read In Java Source Code File As Command Line Argument

Oct 31, 2014

I am trying to complete this question. I understand the most of it but I haven't go a clue to read in the file name.

Full question: Implement a program that reads in a Java source code file and checks to see if it has balanced {}brackets. Your program should use a stack, implemented as a linked list, to check the brackets.

NOTE: you can use a reference called top which points to the head of the list. Your program should run as a command line program and should take a filename as an argument and print one of BALANCED or NOT BALANCED.

For example: c:> java checkBalanced "myProgram.java" BALANCED

Reading TXT File As Command Line Argument?

Apr 23, 2015

I'm having trouble with how to read a text file into my program so the words can be sorted alphabetically. Should I use something like a FileReader?

An example of what I'm trying to do is a .txt file that holds the statement "java is a simple object oriented and distributed and interpreted and robust and secure and dynamic."

The output should organize the words like so: and and and and distributed dynamic interpreted is java object oriented robust secure simple

Here's what I have:

public static void main(String[] args) {
if (args.length != 1) {
System.out.println("Usage: java AscendingAlphabet"

[Code].....

I can never get it to read the file correctly, it just prints the "usage: java..." statement.

JRE :: Rejecting Attempt To Specify Unsupported Characters In Command-line Argument

Oct 30, 2014

We are testing the newest release of JRE 1.6.0_85 (x86).  We are running into an issue when Java launches through IE 10.  We are seeing a command prompt window with the following message as soon as Java launches in IE 10:
 
Rejecting attempt to specify unsupported characters in command-line argument: -D java.security.manager
 
The window is labeled: C:Program Files (x86))Javajre6binjp2launcher.exe
 
The application using Java does launch and run correctly, but the command prompt window stays until the application is closed and Java is stopped.
 
If we add the URL for the website using java to our trusted sites in the local intranet zone and turn off protected mode for that zone, then the command prompt window does not display.  This does not happen with the previous version of JRE (1.6.0_81).  What has changed in this newest version?  We do not want to turn off protected mode.

Declare Array Of 50 Elements Of Type Double - Print Output 10 Elements Per Line

Feb 5, 2015

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class array
{
public static void main(String[] args)

[Code] ...

Is there a way to write this, where, alpha is one array.

Write a program that declares an array "alpha" of 50 elements of type "double". Initialize the array so that the first 25 elements are equal to the square of the index variable and the last 25 elements are equal to three times the index variable. Output the array so that 10 elements per line are printed.

If I have an array of 50 integers, can I break that to read in lines of 10?

Using Printf Command - Java Automatically Moving To Next Line

Aug 4, 2014

I'm learning about the printf command, and when I have it, it is not letting me ad an input. Here is my quick little program:

import java.util.Scanner;
public class TestingPrintF {
public static void main(String[] args) {
// Create a Scanner
Scanner input = new Scanner(System.in);

[Code] ....

The first section works good, but when i move down to the second part it just automatically finishes without letting me enter a phrase.

Cannot Run Java Program That Is Using External Library From Command Line

Mar 30, 2015

I am reading the excellent book Algorithms. The author of this book is using his own libraries.

I have downloaded the libraries (it is a file called stdlib.jar) and I've store it in a directory called ~/Downloads(I am using a macbook pro).

Then I have created a project with IntelliJ Idea 14.1 using the default package (as it is the only way for a program to 'see' these libraries).

The program is running inside the ide, but because of the nature of this book, all the included code must be run from the command line.

The problem is that I cannot run for example the Average class from the command line because the system asks for the external library.

Specifically the error is :

I enter : java -cp . Average

and the Error I get is :

Exception in thread "main" java.lang.NoClassDefFoundError: StdIn
at Average.main(Average.java:11)
Caused by: java.lang.ClassNotFoundException: StdIn
at java.net.URLClassLoader$1.run(URLClassLoader.java:372)

[Code] ....

The Average class is the following :

public class Average {
public static void main(String[] args) {
//Average the numbers on StdIn
double sum = 0.0;
int cnt = 0;

[Code] .....

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).

Command Line And Two Arguments

Sep 14, 2014

i have to run my program from the command line...My code is:

public static void main( String[] args )
{
 
// check command-line arguments
if ( args.length == 2 )
{
// get command-line arguments
String databaseUserName = args[ 0 ];
String databasePassword = args[ 1 ];
 
[code]....

Now everything works in Netbeans but running it from the command line, i get an error message ".java uses unchecked and unsafe operations".I have added a bit more code to the code above

for (int i = 0; i < args.length; i++) {
System.out.println("args[" + i + "]: "
+ args[i]);
}

Just not sure how to run it from the command line,

Command Line Program

Feb 8, 2014

I have a program that runs in the terminal (I use Ubuntu). It asks the user for a String, does something with it, and terminates.It works in the NetBeans terminal, but not outside of it. Specifically, regardless of what I input, it doesn't continue with the program. I enter something, press enter and it just goes to the next line in the terminal.

Java Code:

Scanner scan=new Scanner(System.in);
System.out.println("Enter the music directory:");
String path=scan.nextLine(); mh_sh_highlight_all('java');

how do I pass in arguments when I run the program (still in Linux)? Is there a way to check if the program was launched from the terminal or not?
