    Post cmd prompt exception "could not find or load main class test.java"

    Hello, I'm getting the exception in cmd prompt while running the java program even after it is compiled successfully. I don't know why it can't find the .class file when .java file was available a moment before. I read so many threads relating to this exception and i also did as they said to recreate new java file and compile and run it. But then also it is not working properly. It was working good before 3 months. From last three months this exception has become permanent. Please help me to run files through command prompt. Since it is not working i'm using netbeans now



    Thanks in advance

    Did you use the javac command to compile the program:
    javac test.java
    if there is no error message, the above creates a test.class file
    To execute that code enter:
    java test

    If there are problems:
    On Windows: To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.
    If you don't understand my answer, don't ignore it, ask a question.

    What is in the file: test.java?
    Did the compiling of test.java create a test.class file? Use the dir command to see what is in the folder with the test.java file.
