Java Eclipse homework. I need help coding this

Project 5A - Mixed Results

package: proj5A
class: MixedResults

Create a new project called MixedResults with a class called Tester. Within the main method of Tester you will eventually printout the result of the following problems. However, you should first calculate by hand what you expect the answers to be. For example, in the parenthesis of the first problem, you should realize that strictly integer arithmetic is taking place that results in a value of 0 for the parenthesis.

double d1 = 37.9; //Initialize these variables at the top of your program
double d2 = 1004.128;
int i1 = 12;
int i2 = 18;

Problem 1: 57.2 * (i1 / i2) +1
Problem 2: 57.2 * ( (double)i1 / i2 ) + 1
Problem 3: 15 – i1 * ( d1 * 3) + 4
Problem 4: 15 – i1 * (int)( d1 * 3) + 4
Problem 5: 15 – i1 * ( (int)d1 * 3) + 4

Your printout should look like the following:

Problem 1: 1.0
Problem 2: 39.13333333333333
Problem 3: -1345.39999999999
Problem 4: -1337
Problem 5: -1313

Answer 1

public class MixedResults {

   public static void main(String[] args) {

       Tester test = new Tester();

       test.tester_method();

   }

   

}

class Tester{

   double d1 = 37.9, d2 = 1004.128;

       int i1 = 12, i2 = 18;

   Tester(){  

       

   }

   void tester_method(){

       System.out.println(57.2*(i1/i2)+1);

       System.out.println(57.2*((double)i1/i2)+1);

       System.out.println(15 - i1 * ( d1 * 3) + 4);

       System.out.println(15 - i1 * (int)( d1 * 3) + 4);

       System.out.println(15 - i1 * ( (int)d1 * 3) + 4);

   }

}

I think this is what you're looking for. Best of luck.
