Answer 3

Each primitive datatype has a wrapper class, which need to be distinguished from the datatype itself

Answer 4

The answer is these variables are not numbers variables, but treated as strings.

The place in memory number variables and string variables are treated differently by compiler.

Again the software designers create the rules for compilng the selected language.

Sometime we as humans forget intelligent electronics devices only understand 0's and 1"s. All computer programs no matter the language are reduced to machine language by compiler!. The circuits in the electronics devices use Logic such as OR, AND, NAND, OR, NORD FLIP-FLOPS, CPUs Registers, etc. to community with humans.

Most of these things no longer concern most programmers today. Memories of computers today are inexpensive!

Answer 5

I have posted my opinion on Strings already!!

Answer 6

Ask someone that designs compiler. My previous statement pointed to designers that are over sixty years of age. The stacks and smaller memories means the programmers programmed mostly in Assembler language, which means the programmers push and pop registers. They used 1/1000 the memory used today by programmers.
