A Java Exception has occurred. I just create new folder put JAR file inside that folder and also place lib folder that is used for Java project and finally JAR file is working fine.
The same virtual machine launcher error - java exception has occurred happened with me in eclipse .This error was due to the package name . I changed the package name and the problem solved.
Take a few steps back and add some details. What game version? What version of java are you using? And are you sure that's what the OS is using by default? Open a cmd window and type: java -version while I'm not sure about 1.20, I do know for 1.16.5 and older you need Java 8, for 1.17-1.19.4 use Java 17.
As for the "A Java exception had occurred" error, this may also be because the file requires command line arguments to run. In this case, read the documentation of the program/file to see what you need to do, or ask on a dedicated help forum for the program/file (this is usually also found in the docs)
@Stephen - the question was about " A fatal exception has occurred " while using java --version (two hyphen,) the solution in this answer is to " uninstall that version and install a newer version instead ".
An IO (Input-Output) Exception is predictably caused by something wrong with your input or output. It can be thrown by most classes in the java.io package for many reasons to prevent errors. For example, using a scanner to read data and receiving an invalid type or writing data into a file that doesn't exist.
This happens because when you run it thru cmd, you’re explicitly using the correct version of Java, but when your running it by double-clicking on it, you're use whatever javaw.exe is associated with .jar files, and that could be the wrong version (e.g., Java 8 vs Java 24).
I am working on java wicket framework and Apache tomcat. When I tried to start tomcat, it shows Java Virtual Machine Launcher pop window "Could not create the Java Virtual Machine".
I have written a Java program on Eclipse and I'm able to run the program. But when I transfer it to Notepad++ and run it via command prompt. It gave me an ERROR message. Any idea on how to solve i...
The method throws an exception, which basically means it can run into an error and the try catch block is a way to handle that error without your program crashing.
