need some help

// below is my first program with more than one method am having trouble debugging it though. I am new to both programming and java. any help is appreciated.

import java.util.Scanner;

public class checkup
{
private int patientNumber;
private int bloodPressSys;
private int bloodPressDia;
private int ldl;
private int hdl;

public static void main (String[] args)
{
int patientNumber;
int bloodPressSys;
int bloodPressDia;
int ldl;
int hdl;
Scanner inputDevice = new Scanner (System.in);

System.out.print("Please enter a patient number: " );
patientNumber = inputDevice.nextInt();
System.out.print("Please enter patient's Systolic Blood Pressure: " );
bloodPressSys = inputDevice.nextInt();
System.out.print("Please enter patient's Diastolic Blood Pressure: " );
bloodPressDia = inputDevice.nextInt();
System.out.print("Please enter patient's LDL Cholesterol: " );
ldl = inputDevice.nextInt();
System.out.print("Please enter patient's HDL Cholesterol: " );
hdl = inputDevice.nextInt();
}
public static double computeRatio (String[] args)
{
double computeRatio;
computeRatio = (ldl % hdl);
return computeRatio;
}

public static void explainRatio ()
{
System.out.println (" HDL is known as Good Cholesterol. Any ratio of 3.5 or lower is considered optimum. ");
}

public static double patientInfo (String[] args)
{
System.out.println("Patient number is " + patientNumber +
" Systolic Blood Pressure is " + bloodPressSys +
" Diastolic Blood Pressure is " + bloodPressDia +
" Cholesterol number is " + computeRatio + explainRatio);
}
}

I'm not sure what you need help with. Is the program crashing? Does it give some sort of error? Does it melt your computer?

Let us know what the problem is and we're much more likely to be able to help.
