Java双重嵌套for循环实现百钱买百鸡的写法（一）

        //定义一个记录循环次数变量int count = 0;for(int chk = 1; chk <= 100 / 5; ++chk) {for(int hen = 1; hen <= 100 / 3; hen++) {int chilk = 100 - hen - chk;if(chilk + hen + chk == 100 && chilk / 3 + hen * 3 + chk * 5 == 100 && chilk % 3 == 0) {count++;System.out.println("第"+count+"可能：");System.out.println("鸡翁："+chk+"只\t"+"鸡母："+hen+"只\t"+"鸡雏："+chilk+"只\t");}}}System.out.println("一共有"+count+"可能");

执行结果：
