Answer 1

import java.util.*;
This .* will import all all classes which are in util package so again no need to write
import java.util.Scanner;

But if not need all classes, then don't use to import all classes. But here you are using only extra Scanner class methods, then java.util.Scanner; is enough.. Unnecessary classes importing will slowdown execution.

Remove all those extra unnecessary charecters..

Enough all static method, but All is in same class hence no need to call through class name. just ex: sum(2,3) is enough.. So your program has only extra hidden charecters, remove all and give input by require space separating or line by line..
Ex: 2 1 1 ( for addition.)

Answer 2

There are lots spaces which are not just space but some hidden characters "\u0000" So clear the spaces.. and while calling a static method u should call it wilth this syntax : classname.method_name()

Answer 3

Answer 6

Not able to answer in DM. Not working for me.

nextInt() will not ask you input in separate line.. Only nextLine() will consume entire line and goes to next line for next input.. So in this program, you can input just input like 4 5 1 as a space separated, in separate lines also works but not need... Try and reply if any problem....
