asked on Create a class called BarChart that displays a series of asterisks (*) for a specific number.
Dear Java Gurus,
I have an assignment where I need your help.
This is the Question:
Create a class called BarChart that displays a series of asterisks (*) for a specific number. The class’s constructor should have one integer parameter that represents the number of asterisks to display. The class should also have a method called displayBar that displays the series of asterisks.
Create a second class called BarChartTester that contains the mainmethod. The method should ask the user fora number and use the BarChart class to create a BarChart object that displays the appropriate number of asterisks. This should be repeated five times.
The BarChartTester class should produce the following example input/output:
Enter a number: 5
*****
Enter a number: 15
***************
Enter a number: 7
*******
Enter a number: 3
***
Enter a number: 23
***********************
I have attached my code in the question.
I am using Netbeans
The error I am getting is :

That clearly tells you where the error is - your code won't compile. We can't say anything else as you haven't posted your code

Those should be in separate files. Please post them in separate sets of code tags

The first thing you need to do is check your curly braces. You're trying to write too much code before compiling it. You should write/compile in small increments. A class never ends in a semicolon

Sure CEHJ...changed that.
I am wondering how to link both these classes to get the output as required.
