Hello and welcome to Stack Overflow!

Since you are declaring class javatesting1 to be in a package test1, Java expects to find that class in a folder named like the package in order to scan it (using the wildcard). I have tested your code, importing using wildcard *, with a folder structure like this

folder

• javatesting2.java
• test1

  • javatesting1.java

Try editing your folder structure.

Also please try do adhere to coding conventions: class names should be named using CamelCase, e.g. JavaTesting1
