Please dont worry about rewriting using lambda. You can even do 1-4 in puesdocode just please show where the anon class is. Thanks!

Anonymous Class and lambda Expression Exercises Suppose you've defined a function interface. You will take a double array and and return a double value. The interface is defined as below. //this is a function interface which will takes a double array and return a double value. interface myLambda \{ double apply(double[] array ); An array is given {10,9,8,7,6,5,4,3,2,1}, you will ask to write a code for the following tasks. 1. Calculate the sum of the given array. 2. Calculate the average of the given array. 3. Calculate the maximum of the given array. 4. Calculate the minimum of the given array. First, use anonymous class to finish the above tasks. Then rewrite the code with lambda expressions
