Question

Urgent : need to create a java code that has an utput like this

-----------------------------------------------------------------------

Gender % Under 30 % 30 or Over % Total

--------------------------------------------------------------------------------------------------

Female 44 17 61

Male 23 16    39'

--------------------------------------------------------------------------------------------------

Total 67 33 100

The percentages in the table are rounded to the nearest whole number and are percentages of all those who watch the show regularly. Thus, the sum of percentages in the last column of the table must be 100% (ignoring any rounding error).

Sample output

Please enter the person’s age (1..110): 25

Please enter the person’s gender (M/F): M

Please enter whether the person watches the show regularly (Y/N): Y

*displays table*

Do you want to enter another person’s details (Y/N)? if yes then loops

Answer 1

Here is the full code of file Main.java:

import java.util.Scanner;
import java.lang.Math;

public class Main
{
public static void main(String args[])
{
// Using Scanner for Getting Input from User
  
Scanner in = new Scanner(System.in);
int age = 0;
String gender = "";
String ans_show = "N";
String ans_again = "N";
int male_tot_under30 = 0;
int female_tot_under30 = 0;
int male_tot_above_or_equal30 = 0;
int female_tot_above_or_equal30 = 0;
int total_person = 0;
  
int per_u_m = 0;
int per_a_m = 0;
int per_u_f = 0;
int per_a_f = 0;
  
while(true) {
System.out.print("Please enter the person’s age (1..110):");
age = in.nextInt();
  
System.out.print("Please enter the person’s gender (M/F):");
gender = in.next().toUpperCase();
  
System.out.print("Please enter whether the person watches the show regularly (Y/N):");
ans_show = in.next().toUpperCase();
  
if(ans_show.equals("Y")) {
if(gender.equals("M")) {
if(age < 30) {
male_tot_under30++;
} else {
male_tot_above_or_equal30++;
}
} else if(gender.equals("F")) {
if(age < 30) {
female_tot_under30++;
} else {
female_tot_above_or_equal30++;
}
}
total_person = male_tot_under30 + male_tot_above_or_equal30 + female_tot_under30 +female_tot_above_or_equal30;
  
// Display the show_table
System.out.println("-----------------------------------------------------------------------");
System.out.println("Gender % Under 30 % 30 or Over % Total");
System.out.println("------------------------------------------------------------------------");
  
if(total_person > 0) {
per_u_f = Math.round(((float)female_tot_under30/total_person)*100);
per_a_f = Math.round(((float)female_tot_above_or_equal30/total_person)*100);
}
System.out.println("Female " + per_u_f + " " + per_a_f + " " + (per_u_f + per_a_f));
  
if ((male_tot_under30 + male_tot_above_or_equal30) > 0) {
per_u_m = Math.round(((float)male_tot_under30/total_person)*100);
per_a_m = Math.round(((float)male_tot_above_or_equal30/total_person)*100);
}
System.out.println("Male " + per_u_m + " " + per_a_m + " " + (per_u_m + per_a_m));
  
System.out.println("------------------------------------------------------------------------");
System.out.print("Total " + (per_u_m+per_u_f) + " " + (per_a_m+per_a_f) + " ");
if ((per_u_m + per_a_m + per_u_f + per_a_f) > 100 ) {
System.out.print("100\n");
} else {
System.out.print((per_u_m + per_a_m + per_u_f + per_a_f) + "\n");
}
}
  
System.out.print("Do you want to enter another person’s details (Y/N):");
ans_again = in.next().toUpperCase();
  
//System.out.println("You entered.." + age + gender + ans_show + ans_again);
//System.out.println("male female " + male_tot_under30 + " " + male_tot_above_or_equal30 + " " + female_tot_under30 + " " + female_tot_above_or_equal30);
  
if(ans_again.equals("N")) {
System.out.println("....Program ends here....");
break;
}
}
}
}

After compilation run the Main class
The sample output as below

Please enter the person’s age (1..110):6
Please enter the person’s gender (M/F):M
Please enter whether the person watches the show regularly (Y/N):Y
-----------------------------------------------------------------------
Gender % Under 30 % 30 or Over % Total
------------------------------------------------------------------------
Female 0 0 0
Male 100 0 100
------------------------------------------------------------------------
Total 100 0 100
Do you want to enter another person’s details (Y/N):Y
Please enter the person’s age (1..110):66
Please enter the person’s gender (M/F):F
Please enter whether the person watches the show regularly (Y/N):Y
-----------------------------------------------------------------------
Gender % Under 30 % 30 or Over % Total
------------------------------------------------------------------------
Female 0 50 50
Male 50 0 50
------------------------------------------------------------------------
Total 50 50 100
Do you want to enter another person’s details (Y/N):N
....Program ends here....
