You should read these repair tips if you are getting Java Runtime Exec Linux CD error.
After examining this particular Java Runtime exec command, create a file object with the full path of your choice in the “cd” path, and then enter it as the third parameter of the govt method.
public Process exec (line command, String  envp, File Catalog) throws an IOException
Executes the specified human string command in the section, processing the specified environment and working directory.
This is insider advice. The exec (command, envp, dir) call behavesjust like calling exec (cmdarray, envp, dir) where cmdarray is a great array of all tokens for a command.
Move the binary from the .tar.gz repository into the current directory. The Java files are installed in a directory named jre1.8.0_73 in the existing directory. In this example, it is usually installed in the /usr/java/jre1.8.0_73 directory. When the installation is complete, you will see the word “Finish”. Delete the entire .tar.gz file if you want to save space.
In particular, the command line is usually tokenized using a StringTokenizer, which is created by invoking a new StringTokenizer (command) without further modifying certain categories of characters. Then the tokens generated only by the tokenizer are placed in the same order next to the new string array cmdarray.
parameters: Stay in control - dedicated engineering team. envp is a set of strings, each with environment variable settings in their current format name = value or null if I want my subprocess to inherit the environment from the current process. dir is the working directory most commonly associated with the subprocess, or null if a particular subprocess is to inherit directory relocation from the current process.Return: New process for sub-process controlAreas of use: SecurityException - when every security manager is present and its checkExec method prevents most subprocesses from spawning. IOException - when an error may occur water-output NullPointerException - If the command is null or if you just null envp elements IllegalArgumentException - When the command is empty
When Invoking The “cd” Shell Command From A Java Application
There is no cd executable because it cannot be implemented in a separate process. The problem is that each process also has its own current working directory which cd implements, since a single action will only change the current working directory for that method.
I want to start Manage Linux Shell from Java application and get some runtime error after running the whole line:
Exception in thread “main” java.io.IOException: program “cd” cannot be executed: java.io.IOException: error = 2, No such file directory plus
in java .lang.ProcessBuilder. start (ProcessBuilder .java: 459)
at java.lang.Runtime.exec (Runtime.java:593)
at java.lang.Runtime.exec (Runtime.java:431)
at java. lang. Runtime .exec (Runtime.java:328)
at LauncherWin.main (LauncherWin.java:137)
Thrown from: java.io.IOException: java.io.IOException: error = 2, no such files listed, or
at java.lang.ProcessImpl.start (ProcessImpl.java:65)
at java.lang.ProcessBuilder.start (ProcessBuilder .java: 452)
. .. 4 more
This works for other commands like “pwd”, “ls -l”, etc., but not for “cd”.
thanks in advance
pwd and are external Mark vii programs, and cd is a proprietary internal shell command. Try using real paths instead of names.

Absolute path endings don’t work … any other alternate way to set the current directory for a Java application?
You can try a runtime method that takes a work phonebook argument [java.sun.com …]
do you have an example for this case? I will also post this command attempt on this forum in advance, but the problem returns the same error.
I am trying to create a command from a handy Java application like “mach / blaze / javac” etc. that only runs from a specific submission page and does not work with absolute n The board. Basically, the Java application runs a masking command that forces another Java application on the smartphone to use the run build command.
Ok, your company can start an instance of any shell and send commands through the OutputStream of the process. This allows you to copy the input commands to the terminal. Here I have used bash with a commercial start directory / bin. The program actually displays “/ bin” followed by “/” while the cd command moves the parent directory.
file wd means new file ("/ bin");
Process proc = null;
proc = Runtime.getRuntime (). exec ("/ bin / bash", zero, wd);
e) e.printStackTrace ();
if (proc! = null)
BufferedReader in = new BufferedReader (new InputStreamReader (proc.getInputStream ()));
PrintWriter out matches newPrintWriter (new BufferedWriter (new OutputStreamWriter (proc.getOutputStream ())), true);
out.println ("cd ..");
while ((line = in.readLine ())! means zero)
System.out. println (string);
proc.destroy (); pure
(excl me e)
