JAVA-通过身高体重计算BMI判断人的体型（普通版）

代码：（给出BMI的相关注释）

abstract class People{
	int weight;
	int height;
	public People(int w, int h) {
		this.weight = w;
		this.height = h;
	}

	abstract public float stature();
	public void drawResult() {
		System.out.print("体重:"+this.weight+"(KG) 身高:"+this.height+"(cm)");
		
//		BMI 
//		float statureResult = this.stature();
//		if (statureResult<= 18.4) {
//			System.out.println("体型：偏瘦");
//		}else if (statureResult <= 23.9 && statureResult > 18.4) {
//			System.out.println("体型：正常");
//		}else if (statureResult < 23.9 && statureResult <= 27.9) {
//			System.out.println("体型：超重");
//		}else if (statureResult > 27.9) {
//			System.out.println("体型：肥胖");
//		} else {
//			System.out.println("啥，应该不会运行到这里吧？");
//		}
		float statureResult = this.weight/this.stature()-1;
		if(statureResult>=-0.1&&statureResult<=0.1) {
			System.out.println("体型：标准");
		}else if (statureResult<-0.1) {
			System.out.println("体型：偏瘦");
		}else if (statureResult>0.1) {
			System.out.println("体型：偏重");
		}else {
			System.out.println("啥，应该不会运行到这里吧？嘿嘿嘿");
		}
	};
}

class Woman extends People {
	Woman(int w, int h){
		super(w, h);
	}

	@Override
	public float stature() {

		//BMI=体重（千克）除以身高（米）的平方（kg/m2）
		//return this.weight/((this.height/100)^2);
		//	女性：(身高cm-70)×60﹪=标准体重
		return (float) ((this.height-70.0)*0.6);
	}
}
class man extends People {
	man(int w, int h){
		super(w, h);
	}

	@Override
	public float stature() {
		
		//BMI=体重（千克）除以身高（米）的平方（kg/m2）
		//return this.weight/((this.height/100)^2);
		//男性：(身高cm-80)×70﹪=标准体重
		return (float) ((this.height-80.0)*0.7);
	}
}
public class PeopleTest {
	public static void main(String[] args) {
		System.out.print("这个男士：");
		man Man = new man(100, 185);
		Man.drawResult();
	}

}
