Thread: New to programming

hi, I am very new to programming and i need help on on this question
"a table have 4 legs, a stool have 3 leg, given 300 legs, find number of tables and stools."

it is to be done with public static void main(String[] args){
I started recently with the class so we only know so much to methods,Conditionals and recursion.

I have done quadratic equations with java. so i may know a thing or two on variables and math methods.
the thing is this question has an equation with two variables. I am to list down the number of stools and tables with System.out.print

so, can anyone tell me what i need to know or just how to start out on this question?

I apologize for my english
thank you in advance


edit:i posted on the wrong section , you can still help me out here

Seems to me that there are multiple solutions to this.

The pen and paper version:

1) 96 stools and 3 tables( (96*3)+(3*4) = 300)
2) 92 stools and 6 tables( (92*3)+(6*4) = 300)
3) 88 stools and 9 tables
...ect.

I find it interesting that the number of tables with 4 legs will be multiple of 3, and the number of stools with 3 legs will be a multiple of 4.

Start here:

public class TableStool
{
  public static void main(String[] args)
  {
//continue writing code
  }
}

I never got as far as quadratics in math, I just looked it up on wiki looks like Greek to me.

However I can think of a way to do it without any complex math.

basically start with a do...while loop:

init your variables first:

Start with 3 tables and less than 4 stools will not satisfy the equation:

int legsLeft, stools, tables = 3;
do
{
//more code goes here
}while (stools > 3);

inside this loop, starting with the 3 tables, subtract that number of legs from 300:
then divide the result by the number of legs in stools:

legsLeft = 300 - (4 * tables);
stools = legsLeft / 3;
 
//OR skip the legsLeft variable:
 
stools = (300 - (4 * tables))/3;

Then setup a println to display the number of tables and stools.

After the println, add 3 more tables, it has to be a multiple of 3:

tables += 3;

And then let the do...while do the rest of the work. This might be too simple to get you that A+ however.

Fixed, lol, I was trying not to spoon feed too much. My book has errors in the examples, a headache, but it makes you figure it out on your own.

Put together the example I showed you. Put the do..while inside of the main, and put the rest of the code inside the do..while.

Sorry if you saw it before I finished editing it. There is a complete example there now.
