Package Question

I saved the file as Exercise1.java but when I compile it I receive errors as stated:
What must I do to resolve these mistakes? I think it’s got to do with the package statement.

package com.acme;
import java.util.*;
public class Exercise1 {
int counter;
public void go() {
int sum = 0;
int i = 0;
while (i<100) {
if (i==0)
sum = 100;
sum = sum +1;
public void main (String args[]) {
Exercise1 instance = new Excercise1();
> javac Excercise1.java

c:\jdk1.3\bin>javac Excercise1.java
Excercise1.java:5: class Exercise1 is public, should be declared in a file named Exercise1.java
public class Exercise1 {
Excercise1.java:20: cannot resolve symbol
symbol : class Excercise1
location: class com.acme.Exercise1
Exercise1 instance = new Excercise1();
2 errors

It's because of a spelling mistake
Inside main change the following line
Exercise1 instance = new Excercise1();
Exercise1 instance = new Exercise1();
and it will work.

You should compile the code like this:

and run it like this:

You need to compile the code like this
javac com/acme/Exercise1.java
only if the file Exercise1.java is in folder com/acme.
Otherwise you can compile like this:
javac -d . Exercise1.java
this will create com/acme directories and add the put classfile in it.
I agree. Here's the link: http://aspose.com/file-tools
