java布尔返回问题/从放入数组的方法中获取因子
在一个小时前发布了一个关于早期问题的帖子,并在4分钟内收到了疯狂的回复后,我会再试试我的运气。程序有5种方法,我目前正在制作所有这些方法,所以它们不会全部出现在这里(由于之前的响应,将其放入)。现在的问题是,我得到的最后一种方法,实际上除了制作打印语句之外,还能做些其他事情,以正确工作。该方法是不完整的,它不仅需要找到所述数的因子,还需要将它们存储在一个数组中,将它们相加,然后确定该数是否完美。最后一个未显示的方法是打印每个数字的实际数组(如果有)。“testperfect”是我遇到问题的方法,在eclipse中,我收到一个错误,说这个方法必须以布尔类型返回结果。任何形式的帮助都将不胜感激
import java.util.Scanner;
public class tgore_perfect
{
private static int count;
private static int perfect;
public static void main ( String args [])
{
count = getNum ();
//System.out.print(count);
boolean check = validateNum();
//System.out.print(check);
while (validateNum() == false)
{
System.out.print ("Non-positive numbers are not allowed.\n");
count = getNum();
}
if (validateNum() == true)
{
for ( int i = 0; i < count; i++ )
{
perfect = getPerfect();
testPerfect();
}
}
}
public static int getNum () //gets amount of numbers to process
{
Scanner input = new Scanner ( System.in );
int counter;
System.out.println ("How many numbers would you like to test? ");
counter = input.nextInt();
return counter;
}
private static boolean validateNum() //checks user input
{
if (count <= 0)
{
return false;
}
else
{
return true;
}
}
public static int getPerfect() //gets number to process
{
Scanner input = new Scanner ( System.in);
perfect = -1;
System.out.print ("Please enter a possible perfect number: ");
return perfect = input.nextInt();
}
public static boolean testPerfect() //tests the number to see if is perfect
{
int sum = 0;
int x = 0;
for( int i = 1; i < perfect; i++ )
{
if((perfect % i ) == 0 )
{
x = i;
sum += x;
}
if( x == perfect)
{
return true;
}
else
{
return false;
}
}
}
}
