java compiler errors when compiling fibonacci program

[baldy1324]

i am writing a program in java to do the fibonacci sequence.
here is the code:class main
{
public static void main(String[] args)
{
int n = 350;
double first = 0;
double second = 1;
System.out.print(first);
System.out.print(" ");
System.out.print(second);
System.out.print(" ");

while (n>0)
{
double third = first + second;
first = second;
second = third;
System.out.print(third);
System.out.print(" ");
n--;
}
}
}

when i compile it with javac there are no errors
when i run java to run/interpert it it gives the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: main/class

any ideas?

Perhaps try naming your class something other than main? Weird name for a class.

Not sure what's wrong, I just copy and pasted your code exactly and it worked perfect for me. Did you make sure to name your file main.java?

class name must match filename. E.g. public class DogStar { ... } must be in a file called DogStar.java

when you run it, type:


java main


you don't need a .class extension.

:KS That'll be it

java.lang.NoClassDefFoundError: main/class

Means you have typed java main.class and java interprets this as package main, class class.
