Question

When I want to run my java code, I have this problem :

Exeption in thread "main" java.lang.ArrayIndexOutOfBoundsException:0
     at com.ibm.icu.text.BreakDictionary.main(BreakDictionary.java:44)

i can’t run my code… It’s simple

public class main{
   public static void main(String[] args){
      System.out.print("Hi");
   }
}

Answer 1

WTF is com.ibm.icu.text.BreakDictionary?

Make sure of the class whose main you are running. I suspect you’re not running your class. Your java command should look like this:

java -cp somepath com.mycompany.mypackage.MyClass

Better yet, use an IDE like eclipse that make it easy to run a class

Also, rename your class from main to MyClass – anything with a leading capital letter – it’s good coding style
