Answer 1

Reya Patriarca declare 4 variables if you want and then use conditional statements to get the result.
Edit: It can also be done in other ways.

Answer 2

Scanner scan = new Scanner (System.in);

double first = scan.nextDouble();
double second = scan.nextDouble();
double third = scan.nextDouble();

You can also use an array or you can use a loop:

for (int i = 0; i < 3; i++){

double input = scan.nextDouble();

}

It depends on your skills if you need to store all values to get the max or if you are able to get it by using one loop.

Answer 3

Scanner input = new Scanner(System.in);

System.out.println("Type in three numbers (doubles)");
System.out.println("on a single line:-");

String[] mystring = input.nextLine().split(" ");
if (mystring.length == 3) {
Double first_double = Double.parseDouble(mystring[0]);
Double second_double = Double.parseDouble(mystring[1]);
Double third_double = Double.parseDouble(mystring[2]);

System.out.println(Double.max(Double.max(first_double, second_double), third_double));
}
input.close();
}
