title: Can't import a class in java. Code refuses to believe it exists
body: <p>Okay so I made code that wants to find the area of a circle, triangle and square. There are two java files in my package folder, Mung.
   For some reason I keep getting the error
  Shapes.java:2: error: package Mung does not exist</p>
  
  <p>Here's my code.</p>
  
  <pre><code>import java.io.*; import java.util.*;
  import Mung.*;
  public class Shapes
  {
     public static void main(String args[])
     {
        System.out.println(areaSquare());
        System.out.println(areaCircle());
        System.out.println(areaTriangle());
     }
  }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>import java.io.*; import java.util.*;
  public class ShapesAssignment
  {
     public ShapesAssignment (double r,double h,double w)
    {
    double radius = r;
    double height = h;
    double width = w;
    }
     public double areaCircle()
     {
        double cArea = Math.PI * radius;
        return cArea;
     }
     public double areaTriangle()
     {
        double tArea = (height*width)/2;
        return tArea;
  
      }
      public double areaSquare()
     {
        double sArea = (height*width);
        return sArea;
  
     }
     public double radius;
     public double height;
     public double width;
  }
  </code></pre>
