For instance I compiled this java example given here . compilation is successful. When I try to execute the program, I get the error message, could not find or load mainclass ArrayDemo.
Appreciate your help.

Hi -
When I compile the program using command prompt, I am in C:\Users\Farooq\MyPrograms directory. MyPrograms is where all my programs are.
Below is the actual program, it does not have package statement.
class ArrayDemo {
public static void main(String[] args) {
     int[] anArray; // declares an array of integers
anArray = new int[10]; // allocates memory for 10 integers
anArray[0] = 100; // initialize first element
anArray[1] = 200; // initialize second element
anArray[2] = 300; // etc.
anArray[3] = 400;
anArray[4] = 500;
anArray[5] = 600;
anArray[6] = 700;
anArray[7] = 800;
anArray[8] = 900;
anArray[9] = 1000;
System.out.println("Element at index 0: " + anArray[0]);
System.out.println("Element at index 1: " + anArray[1]);
System.out.println("Element at index 2: " + anArray[2]);
System.out.println("Element at index 3: " + anArray[3]);
System.out.println("Element at index 4: " + anArray[4]);
System.out.println("Element at index 5: " + anArray[5]);
System.out.println("Element at index 6: " + anArray[6]);
System.out.println("Element at index 7: " + anArray[7]);
System.out.println("Element at index 8: " + anArray[8]);
System.out.println("Element at index 9: " + anArray[9]);
}
