合計点、平均点の求め方

public class Main {
public static void main(String[] args) {
int [] scores = {20, 30, 40, 50, 80};
int sum = 0; //集計結果
for (int i = 0; i < scores.length; i++) {
sum += scores[i]; //変数sumに合算
}

	int avg = sum / scores.length;
	System.out.println("合計点:" + sum);
	System.out.println("平均点:" + avg);
	
}

}
