title: Can't import class from the same package
body: <p>I am new to Java and can't find my mistake, the compiler gives me this error message:</p>
  
  <pre><code>-&gt;javac B.java
  B.java:3: error: cannot find symbol
  import a0.A;
           ^
    symbol:   class A
    location: package a0
  </code></pre>
  
  <p>My classes are really simple:</p>
  
  <pre><code>package a0;
  
  import a0.A;
  
  public class B{
      public static void main(String[] args){
          System.out.println("Hello!");
      }
  }
  </code></pre>
  
  <p>Class B</p>
  
  <pre><code>package a0;
  
  public class A {
  }
  </code></pre>
  
  <p>Class A</p>
  
  <p>I work under Ubuntu 16.04, both classes are in the same directory.</p>
