使用 Math.random()来实现百钱百鸡方法？
我换了很多种方法
不管是嵌入FOR循环   还是   if语句
都要报错。
无法使用random   来实现百钱百鸡呢？

高手麻烦写个来看看

public class Baiqian
{
public static void main(String [] args)
{
int x=0,z=0;
int y;
for(int i=0;i <20;i++){
x=i;
for(int j=3;j <100;j+=3){
z=j;
y=100-x-z;
if(5*x+3*y+z/3==100&&y> 0&&x> 0){
System.out.print(x+ "\t "+y+ "\t "+z+ "\t ");
System.out.println();
}
}
}
}
}
这是我最初写的代码。
直接给你贴出来了。

public class Chicken {
private static int chicken1 = 15;
private static int chicken2 = 9;
private static int chicken3 = 1;
private static int total = 300;

/**
* @param args
*/
public static void main(String[] args) {
for (int i = 0; i <= 20; i ++ ){
for (int j = 0; j <= 34; j ++ ){
for (int k = 0; k <= 300; k += 3){
if( i*chicken1 +j*chicken2+k*chicken3 == total){
System.out.println( "( " + i + ", " + j + ", " + k + ") ");
}
}
}
}
}

}

输出结果：
