へロンの公式ってそうだったっけか？
俺の記憶だとこれなんだが，間違ってたら直せ
public class Menseki {
double a;
double b;
double c;
public Menseki(double a,double b, double c){
this.a = a;
this.b = b;
this.c = c;
}
public double getA() {
return a;
}
public double getB() {
return b;
}
public double getC() {
return c;
}
public double getMenseki(){
double s = (a+b+c)/2;
return Math.sqrt(s * (s - a) * (s - b) * (s - c));
}
}
