Lambda Widgets

Use the supplied Widget class

In the primary logic, instantiate an ArrayList of Widget Loop 20 times

In each iteration use a Supplier to get a randomly generated Widget

The value should be a random value from -10 to 90

The name should be a String made of random uppercase letters (ASCII codes 65 to 90)

For each random Widget, use a Predicate to test if the value is zero or greater.

If the Widget has a positive value, use a UnaryOperator to convert the Widget name to all lowercase letters, then add the Widget to the ArrayList

If the Widget has a negative value, ignore that Widget and move on

Outside of that loop, create another loop to iterate through the ArrayList

For each iteration, use a Consumer< Widget> to print each Widget on its own line

Do not use the toString() method of Widget

The format should be: Widget[ value: 77 name: pfwiiqdd] where the fields for value and name have a fixed width
