How many bits would you need to represent each of the 87 stu

How many bits would you need to represent each of the 87 students using a unique permutation of bits in a binary number system? Please explain the reasons To import all classes in a particular package java, util, which kind of sentence we should write? What output is produced by the following? System.out.println(\"A\" + 75); System.out.println(\"B\" + (75 + 100)); System, out.println(\"C\" + 30 + 40); System.out.println(30 + 40);

Solution

2.1. It would take 7 bits to represent each of the 87 students. Six bits are not enough because 2⁶= 64 but seven bits would be enough because 2⁷= 128.

2.2 import all the classes from the particular package:

2.3. Outputs:
A75
B175
C3040
70
