Java编程问题修改

Question

这是一个Java的分解质因子程序 想问一下如何删除最后打印出来的那个* ？

package test;
import java.util.Scanner;
public class test {
public static void main(String[] args)
{
    System.out.println("Hello world!");
    Scanner s= new Scanner(System.in);
    int n=s.nextInt();
    System.out.print(n+"=");
    for(int i=2;i<=n/2;i++)
    {
        while(n%i==0)
        {
            System.out.print(i+"*");
            n/=i;
        }
    }
    s.close();
}
}

package test;
import java.util.Scanner;
public class test {
public static void main(String[] args)
{
    Scanner s= new Scanner(System.in);
    int n=s.nextInt();
    System.out.print(n+"=");
    for(int i=2,t=n;i<=n/2;i++)
    {
        while(t%i==0)
        {
            System.out.print(i+(t!=i?"*":"\n"));
            t/=i;
        }
    }
    s.close();
}
