Answer 1

u store integers in int type

Answer 2

in mathematics/programming perspective number have two type:
NUM_TYPE_1]number without decimal precision point(with + or - sign)
NUM_TYPE_2]number with decimal precision point(with + or - sign)

now ,
NUM_TYPE_1 is supported by long & double data type in java or any language.
Capacity: 8 Byte(java)
Ex:
long l1=10;//✓✓valid in java****👍👍.
long l1=10.20//✓✓invalid in java ****👎👎.

NUM_TYPE_2 is supported by only double data and not supported in long datatype type in java or any language.
capacity: 8Byte(java)
Ex:
double d1=10;✓✓valid in java****👍👍
double d_a=20.40;//✓✓also valid ****👍👍

i hope you understand and this ans is explain based on what i know about datatype and all and if you feel wrong this one please give comment here i always appreciated that
thank you for your questions

Answer 3

a double is a floating point number with higher precision since it uses double the amount of bytes to represent itself. Usually 4 bytes for a float and 8 bytes for a double, but this is totally platform-dependent.
