------解决方案--------------------
两层就够了。
for ( int i = 0 ;i <=10;i++){
for(int j= 0;j<=30-3*i;j++){
int count = 3*i+2*j+(30-i-j);
if(count==50){
System.out.println(i+" "+j+" "+(30-i-j));
}
}
}

public class Test21 {

for (int man = 0; man < 17; man++) {
for (int woman = 0; woman < 26; woman++) {
if (man * 3 + 2 * woman + (30 - man - woman) == 50) {
System.out.println("男人有:" + man);
System.out.println("女人有:" + woman);
System.out.println("小孩有:" + (30 - man - woman));
System.out.println("****************");
}
}

System.out.println("程序结束!");
