Help me out with this in Java:

1. Create an array 1, 23, 4, 4, 22, 34, 45, 11, 33. Use lambda to find the smallest number in the array. Deduplicate the array, and multiply each element of the deduplicated array by 2, and then find the sum of the arrays multiplied by 2, for example, arrays 1,2,3,3, after deduplication is 1, 2, 3, multiplied by 2 is 2, 4, 6, and the final sum is 12. 2. Define an interface (Eatable), which defines an abstract method: void eato; Define a test class (EatableDemo), provide two methods in the test class One method is: use Eatable(Eatable e) One method is the main method, call the useEatable method in the main method
