Answer:
Hi DancingGrace! The issue with the code is that it is trying to extend multiple classes which is not a feature in Java programming.
Explanation:
The extends keyword allows a class to use the attributes and properties of the base class it is extending and add more features and properties into it's own class. This is useful in programming where different models share similar properties but are slightly different. An example would be designing a class for Car and Bike. Both have some similar properties like wheels, engine, etc, however they are different forms of transport. A useful implementation would be to define a class called Vehicle with similar attributes, and have the Car and Bike extend it.

Answer:
2048 blocks
Explanation:
From the information given:
The memory size of a computer with fully associative cache = 2¹⁶ bytes
The no. of blocks in a single cache = 64
In which each block size = 32 bytes
The no of blocks in the main memory = memory size ÷ block size
The no of blocks in the main memory = 2¹⁶ ÷ 32
The no of blocks in the main memory = 2¹⁶ ÷ 2⁵
The no of blocks in the main memory = 
The no of blocks in the main memory = 2¹¹
The no of blocks in the main memory = 2048 blocks
