[Java知识库]【java】打卡

之前学过一点java，最近再看看

一、鸡鸭鹅问题

public class Egg {
	public static void main(String[] args) {
		int chicken = 0, duck = 0, goose = 0;
		for( int i = 0; i < 100; i++)
		{
			chicken = i;
			for( int j = 0; j < 100; j++) {
				duck = j;
				goose = 100 - duck - chicken;
				if( chicken + duck * 30 + goose * 60 == 1000 && chicken > 0 && duck > 0 && goose > 0) {
					System.out.println("鸡:" + chicken + "鸭:" + duck + " 鹅:" + goose);
				}
			}
		}
	}
}

success

这个chicken + duck * 30 + goose * 60 == 1000 为啥称30，乘60，我乘3，乘6等于100不行吗？
