    Default calling method question.

    *i am having trouble with calling methods and need to grasp the concept in order to pass a class.
    the program was supposed to collect from the user their systolic, diastolic, ldl and hdl and then the compute ratio method
    was supposed to calculate the ratio of ldl/hdl. and im not sure what's wrong.

    import javax.swing.JOptionPane;
    import java.util.Scanner;
    public class checkup
    {
    public static void main(String[] args)
    {
    String name;
    int patientnumber=335;
    int systolic = 85;
    int diastolic=120;
    int ldl=30;
    int hdl=60;
    public int getsystolic()
    {
    return systolic;
    }
    public int getdiastolic()
    {
    return diastolic;
    }
    public int getldl()
    {
    return ldl;
    }
    public int gethdl()
    {
    return hdl;
    }
    Scanner inputDevice = new Scanner(System.in);

    System.out.print("Please enter your systolic >>");
    systolic = inputDevice.nextInt();

    System.out.print("Please enter your diastolic >>");
    diastolic = inputDevice.nextInt();

    System.out.print("Please enter your ldl >>");
    ldl = inputDevice.nextInt();

    System.out.print("Please enter your hdl >>");
    hdl = inputDevice.nextInt();

    }

    public static int computeRatio(int ldl, int hdl)
    {

    int result=0;
    result = ldl/hdl;
    return result;

    }
    }

    im not sure what's wrong.
    Can you describe "what's wrong"? If you are getting error messages, copy the full text and paste it here.
    If the program's results are wrong, post the results and add some comments saying what is wrong and what the results should be.

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    I can't see where you are calling the computeRatio() method from main.

    I apologize I am new to this. and here are the errors.
    and my instructor is not being very helpful.


    ----jGRASP exec: javac -g checkup.java
    checkup.java:43: illegal start of expression
    public int getsystolic()
    ^
    checkup.java:43: ';' expected
    public int getsystolic()

    public int gethdl()
    ^
    checkup.java:56: ';' expected
    public int gethdl()
    ^
    8 errors



    So where exactly do i need to call the method. outside of both of the classes.

    First you need to correct the compiler errors. Check that all the {}s are properly paired and in the correct locations.
    The compiler has gotten lost at line 43.
    If you don't understand my answer, don't ignore it, ask a question.
