People.java:52: 需要 ".class" paixu(people[]); ^ People.java:52: 需要 ')' paixu(people

People.java:52: 需要 ".class" paixu(people[]); ^ People.java:52: 需要 ')' paixu(people[]); ^

错误主要出现在paixu（）函数中，现将paixu（）函数修改如下：
public void paixu(People people[])
{
People temp;
for(int i=0;i<9;i++)//你一共定义了9个people对象，故i取值应该是从0到8
{ for(int j=i+1;j<9;j++)
{
if(people[i].height { temp=people[i];//注意temp是People类型，不能将people[i].height赋值给它
people[i]=people[j];
people[j]=temp;
}
}
System.out.println(people[i].toString());//应该调用people[i]的toString()方法
}
}
