[JAVA]计算完美数并输出

public class PerfectNum
{
public static void main(String args[])
{
int count=0;
Perfect pn = new Perfect();
for(int i=1;i<10000;i++)
if(pn.isPerfect(i))
{
System.out.print(i+"/t");
count++;
if(count%3==0)
System.out.println();
}
}
}

class Perfect
{
int i;
boolean isPerfect(int x)
{
int y=0;
for(i=1;i<x;i++)
{
if(x%i==0) y+=i;
}
if(x==y) return true ;else return false;
}
}
