Answer 1

import java.util.Scanner;
public class PoorRich {
public static void group(double total){
if(total>=10000.00){
System.out.println("rich");
}
else{
System.out.println("poor");
}
}
public static void main(String[] args){
double total=0;
Scanner input= new Scanner(System.in);
System.out.println("enter the number of siblings:");
int siblings=input.nextInt();

double[] income = new double[siblings];

System.out.println("enter income of the family:");

for(int i=0; i<siblings; i++) {
income[i] = input.nextDouble();

total +=income[i];
}
group(total);
}
}

//I test this check it once working 100%
//For execution it asks input lines for example: "5 8000 4000 6000 3000 1000" then submit for the 5 member of total: 22000 >10000 you will get output as rich

Answer 2

All the best👌

Answer 3

Hey i changed total=total+income[i];
Now for 3 siblings 2000,1000,4500 total is 7500 the output is poor

Answer 4

Here it is
You are giving 3 siblings
Then after in array you are specifically income for each sibling
Income[1st sibling,2 sib, 3 sib]=[2000,1000,4500]
Total will be 2000+1000+4500
But 7500 is less than 10000
So output is poor

Answer 5

but it show error when i put [size_of_array];
public class PoorRich {
public static void main(String[]args){

double total;

Scanner input= new Scanner(System.in);
System.out.println("enter the number of siblings:");
int siblings=input.nextInt();

double[]income = new double[size_of_array];

System.out.println("enter income of the family:");

for(int i=0; i<siblings; i++) {
income[i] = input.nextDouble();
}
total = income * siblings;
group(total);
}
public static void group(double total){
if(total>=10000.00){
System.out.println("rich");
}
else{
System.out.println("poor");
}
}
}

like this?

Answer 6

Aaaaa i dont get it😭😔 why we must specify array when user already enter the number of siblings?

Answer 7

It still have error on

total = income*siblings;
group(total);

Answer 8

It's work, but double and int cant be solved, right? So, I need to change the datatype?
