Highest Of Three Grades

So I have created this program but I am having a couple of small problems with it. The first problem is that the user inputted numbers should all be on the same line. I have spent hours trying to figure this out and I have looked online but I've had no luck. The second problem is that the "lowest score" should be 42 and not 42.0. I don't understand how to make it so the number is an integer. I have posted the output that i'm getting and the way the output should look like at the bottom.

import java.util.Scanner;
public class Random
{
public static void main(String [ ] args) {
Scanner input = new Scanner(System.in);
double a, b, c;

[Code] .....

This is the output that i'm getting.

Enter three scores: 87
42
94

The average is: 74.33333333333333
The lowest score was: 42.0
The average without the lowest score is: 90.5
The grade is: A

This is the way the output should look like.

Enter three scores: 87 42 94

The average is: 74.33333333333333
The lowest score was: 42
The average without the lowest score is: 90.5
The grade is: A
