Hi,
I have a program to write for a chapter on loops and I have no clue where to start. I have to write a program that take in an int and prints the factors of the numbers.

example:

Please enter a number : 12
1
3
4
12

If you guys can help i would really appreciate it. Thanks.

Use a for-loop to loop through the numbers until the loop reaches the number. You can check if a certain number is a factor of the entered int, by using the %-operator. The %-operator gives you the remainder of the division. Thus if a certain number is a factor of the entered int, then the remainder will be equal to 0.

this is what i got so far but it still doesn't work. i can't get the any number to print except for 0;
my book says i have to use the nextFactor method and the hasNextFactor method and that it has to print this way
example:
150
2
3
5
5
if you could help me with this I would really appreciate it. Thank guys.

public class FactorGenerator
{
public FactorGenerator(int aNum)
{

num = aNum;
divBy = 1;
}


public int nextFactor()
{
while(divBy < num)
{
divBy++;
factor = num % divBy;

}
return factor;
}
public void hasNextFactor()
{
for (int i = 1; i < num; i++)
{
factor = num % divBy;

}

}



private int num;
private int divBy;
public int factor;
}

You don't need the divBy. It is enough to divide by the i variable. That variable already holds the divisor.

hmmmmm. Your code is a little confused. Where is your main() method ? The following code produces the desired output and uses your method and variable names with some modification. When you have compiled it type : java FactorGenerator 12
to produce all the factors of 12. Replace 12 with any other number you wish to obtain the factors of that number.

public class FactorGenerator
{
public FactorGenerator(int aNum)
{

num = aNum;
divBy = 1;

}

public void nextFactor()
{

factor = num % divBy;
divBy++;

}

public void hasNextFactor()
{

for (int i = 1; i <= num; i++)
{

nextFactor();
if (factor == 0 ) System.out.println( i );

}

}

public static void main (String[] args)
{

FactorGenerator fg = new FactorGenerator ( Integer.parseInt ( args[0] ));
System.out.println ( fg.num );
fg.hasNextFactor();

}

private int num;
private int divBy;
public int factor;
}
