問題３はこれでOK？

public class AverageOfSuccessor {
public static void main(String[] args) {
int student1 = 89;
int student2 = 55;
int student3 = 32;
int student4 = 94;
int student5 = 60;

int count = 0;　
int sum = 0;　
if(student1 >= 60) {　count++;　sum += student1;　}
if(student2 >= 60) {　count++;　sum += student2;　}
if(student3 >= 60) {　count++;　sum += student3;　}
if(student4 >= 60) {　count++;　sum += student4;　}
if(student5 >= 60) {　count++;　sum += student5;　}
int average = sum / count;
System.out.println("点数が60点以上の人の平均値は" + average + "点ですた。");
}
}
