java计算题求解

[Candy_SS]

青蛙跳井问题，井深100米，青蛙往上跳5米往下滑4米，问多少天能跳上去？
要用java思想实现，求高人指点

(100 - 5)/(5 - 4) + 1=96

这种蛋疼的题目估计只有我这种蛋疼的人才会去写

package temp;

class Frog {
	private int jumpDistance; // 青蛙跳的距离

	public Frog() {
		this.jumpDistance = 0;
	}
    //青蛙上跳
	public void jump() {
		this.jumpDistance += 5;
	}
    //青蛙下滑
	public void slip() {
		this.jumpDistance -= 4;
	}
   //获得青蛙已经跳了的距离
	public int getJumpDistance() {
		return this.jumpDistance;
	}
}

public class Test {
	public static void main(String[] args) {
		int day = 0;
		Frog frog = new Frog();
		while (frog.getJumpDistance() < 100) {
			day++;
			frog.jump();
			if (frog.getJumpDistance() < 100) {
				frog.slip();
			}
		}
		System.out.println("共需要"+day+"天");
	}

}

...3楼写得不错。。

[zzp_407901474]

package frog;
public class Frog{

int jumpdistance=0;
int day=0;

//传个参数,井多深都能算
public int getday(int deep){

while (jumpdistance<deep){

day++;
jumpdistance=jumpdistance+5;
if(jumpdistance<deep){

jumpdistance=jumpdistance-4;
}


}
return day;

}

}

package frog;

public class Test {
public static void main(String[] args) {

Frog frog = new Frog();
int day=frog.getday(100);
System.out.println(day);

}

}
