### java game creation i would like to know how to calculate the total value of random numbers

It's been a month and a half since I started studying Java, and I have the task of creating a simple game.
The contents of the game are as follows.
・ 3 players
・ Roll the dice 3 times each and find the total value for each.
・ The person with the largest total value wins

I'm creating it using an array and random numbers, but I'm stumbling because I don't know how to write the code to find the total value.
I would appreciate it if you could teach me.
I look forward to working with you.

: 5 3 1
9 ← The total value is not calculated, and it seems that the random number is output as it is.
: 2 6 3
8 ← The total value is not calculated, and it seems that the random number is output as it is.
: 5 2 6
5 ← The total value is not calculated, and it seems that the random number is output as it is.

Corresponding source code

package test;

public class SaikoroGames {

public static void main (String [] args) {

// Decide the number of players
int [] r = {1,2,3};

int sum = 0;

// Loop for the number of people
for (int j = 0;j System.out.print ("[" + r [j] + "]" + ":");
for (int i = 0;i for (int n = 0;n<1;n ++) {
System.out.print (dice () + "");
sum = dice () + dice () + dice ();
}
}
System.out.println ();
System.out.print (sum);
System.out.println ();
}
}

// roll the dice
static int dice () {
return (int) (Math.random () * 6) + 1;
}
}

What I tried

I googled how to find the total value using an array and random numbers, but it didn't work.

Supplementary information (FW/tool version, etc.)
• Answer # 1

The cause is here

``````for (int i = 0;i<r.length;i ++) {
for (int n = 0;n<1;n ++) {
// Here, a random number is generated and displayed.
System.out.print (dice () + "");
// I am trying to make a total value here, but it is not the number displayed above because it has nothing to do with the random number above
sum = dice () + dice () + dice ();
}
}``````

The dice function only describes the process of randomly creating numbers.
So the dice () displayed in print and the dice () performed in sum areIt's a different thing
If you tell me completely, it will not be good for you, so I commented on the pointed out part.

About two hints (almost the answer) of the solution
-Let's define a variable once and put it in it instead of displaying dice () directly. Then you can use it for other processing without losing the numerical value.

``````int hokan = 0;
hokan = dice ();``````

・ How about calculating the total value every time you ask for a random number?

``sum + = ○○``

Something is entered in ○○. It is the same as the one displayed by print, so you should be able to do it by referring to the first hint.
Please do your best.

The total value is not calculated, and it looks like the random number is output as it is.

You can only see it (if you put it out as it is, you won't get "8" or "9"). The total value of the random numbers is actually recorded.

However, in the total calculation and output respectively`dice ()`Is called, so the displayed value is not used for the total.
