Question

Java - i have the program working here, I just need help aligning the columns correctly because they do not center correctly. For example, all the names need to be in the far left (which is not happening as of this point)

import java.util.Scanner;
import java.text.DecimalFormat;

public class HealthCheck {

public static void main(String[]args) {

//variables
Scanner reader = new Scanner(System.in);
DecimalFormat f = new DecimalFormat("##.0");
String name;
int heartRate;
int respiratoryRate;
int height;
int weight;
int systolicPressure;
int diastolicPressure;
double BMI;
int score;

System.out.println("Name Heart Rate Resp Rate Height Weight BMI BP Score");

//input
while(reader.hasNext()){
name = reader.next();
heartRate = reader.nextInt();
respiratoryRate = reader.nextInt();
height = reader.nextInt();
weight = reader.nextInt();
systolicPressure = reader.nextInt();
diastolicPressure = reader.nextInt();

BMI = (((double)weight)* 0.453592d)/((((double)height)*0.0254) * (((double)height)*0.0254));

if(heartRate == 0 || respiratoryRate == 0 || height == 0 || weight == 0 || systolicPressure == 0 ||
diastolicPressure == 0) {
System.out.println("Invalid record");
}
else {
System.out.print(name+" ");
}

score = 1;
if(heartRate >= 60 && heartRate <= 100){
score++;
System.out.print(heartRate+" ");
}
else {
System.out.print("!!"+heartRate+" ");

}
if(respiratoryRate >= 12 && respiratoryRate <= 18) {
score++;
System.out.print(respiratoryRate+" ");
}
else {
System.out.print("!!"+respiratoryRate+" ");
}

System.out.print(height+" ");
System.out.print(weight+" ");
System.out.printf(f.format(BMI)+" ");

if((systolicPressure >= 90 && systolicPressure <= 120)&&(diastolicPressure >= 60 && diastolicPressure<=80)) {
score++;
System.out.print(systolicPressure+"/" +diastolicPressure+" ");
}
else {
System.out.print("!!"+systolicPressure+"/" +diastolicPressure+" ");
}

for(int i=0; i System.out.print("*");
}
System.out.println();
}
}

Explanation / Answer

Use a format specifier to print data with specific format of a specific width. Define width of each column before printing it. An integer and string example is given below:

String formatInt = "%5d"; // To print 5 digit integers

System.out.format(formatInt, VARIABLE_TO_BE_PRINTED);

String formatStr = "%-50s"; // To print 50 characters string

System.out.format(formatStr, VARIABLE_TO_BE_PRINTED);

In this code add below statements:

For printing name:

String formatStr = "%-20s"; // Assuming max length of a name is 20 chars

System.out.format(formatStr, name);

All the other columns are of width 3 so print as below:

String formatInt = "%3d";

System.out.format(formatInt, heartRate);

System.out.format(formatInt, respiratoryRate);

System.out.format(formatInt, height);

System.out.format(formatInt, weight);

System.out.format(formatInt, diastolicPressure );

System.out.format(formatInt, systolicPressure);
