其实怎么做思路都一样。
class A {
/**
* 求最大公约数
*/
protected int greatestCommonDenominator(int a, int b) {
int temp;
if (a < b) {
a = a + b;
b = a - b;
a = a - b;
}
while (b != 0) {
temp = a % b;
a = b;
b = temp;
}
return a;
}
}
class B extends A{
/**
* 求最小公倍数
*/
protected int lowestCommonMultiple(int a, int b){
return a*b/super.greatestCommonDenominator(a, b);
}
}
public class Result {
public static void main(String[] args) {
A resultA = new A();
B resultB = new B();
java.util.Scanner scan = new java.util.Scanner(System.in);
System.out.println("输入两个数:");
int inputA = scan.nextInt();
int inputB = scan.nextInt();
System.out.println("两数最大公约数：" + resultA.greatestCommonDenominator(
inputA, inputB));
System.out.println("两数最小公倍数：" + resultB.lowestCommonMultiple(
inputA, inputB));
}
}
你自己可以做到的，类B用继承就好了啊
