Java language/ syntax question. Hello. Can you please demonstrate how I can return 'char' key from a 'char'-key and 'int'-value hashmap. I would like to assign that char key to a primitive char variable. Is there anyway to accomplish this? I am using jdk 11. Thank you.

Suppose you have an object made up of two w-bit integers, x and y. Show why x+y does not make a good hash code for your object. Give an example of a large set of objects that would all have the same hash code. c++ and provide good comments.

2. Write a program by implementing your own PRNG (e.g., using a hash function). You must not use any existing random class or function but implement your own. Produce random bytes (like above). Note the purpose of this part is not to design a strong PRNG that passes randomness tests, but rather for comparison with an existing strong PRNG (above).

This question is for Java, and in the picture provided.
