JAVA循环题，，求大神指教

100元怎么买100个蛋，鸡蛋1毛一个，鸭蛋3元一个，鹅蛋6元一个

 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);
                    }                   
                }
        }               
    }   
}

这不是java问题 是数学问题

 public class HowToBuyEgg {
    public static int getNumberOfEggs(int eggNum,int money,int pChikchen,int pDuck, int pGoose){
        int gooseNum = money/pGoose;
        int duckNum = money/pDuck;
        for(int i = 0; i <= gooseNum;i++){
            for(int j = 0; j <= duckNum;j++){
                if((pGoose*i+pDuck*j+(eggNum-i-j)*pChikchen*0.1) == money){
                    System.out.println("All "+money+" RMB can buy "+(100-i-j)+" eggs and " + j + " duck eggs and "+ i + " goose eggs");
                }
            }
        }
        return 0;
    }

    public static void main(String args[]){
        getNumberOfEggs(100,100,1,3,6);
    }
}

All 100 RMB can buy 70 eggs and 29 duck eggs and 1 goose eggs

 //x+y+z=100
//0.1x+3y+6z=100

for(int x=1;x<=100;x++){
    for(int y=1;y<=100;y++){
        for(int z=1;z<=100;z++){
            if( (x+y+z=100) && (0.1x+3y+6z=100) ){
                System.out.println("鸡:"+x+"  鸭:"+y+"  鹅:"+z);
            }
        }
    }
}
