初学java，鸡兔同笼求解

Question

public static void main(String[] args){
int rabbit=0;
int chicken=0;
if(rabbit+chicken==35&&2*chicken+4*rabbit==94){
System.out.println(rabbit);
}

}
这样为什么不可以啊？

Answer 1

你要写
for (int rabbit=0; rabbit <= 100; rabbit++)
for (chicken=0; chicken <= 100; chicken++)
{
if(rabbit+chicken==35&&2*chicken+4*rabbit==94){
System.out.println(rabbit);
}
