How to use Scanner get store input in one integer

Question

How can I make it so the there will be the same number of questions as the user inputs the number of jobs. For example, lets say you had worked in 5 jobs, I want the program to ask the user to ask, Your salary for job 1 Job 2 Job 3 Job 4 Job 5, and so on. My code right now is.

 import java.util.Scanner;
public class Personal_Info {
public static void main(String[] args) {


     Scanner Scanner = new Scanner(System.in);

    int Salary1;
    int Salary2;
    int Salary3;
    int TotalJobs;
    int Average;
    String Name;
    int Largest;
    int Smallest;
    int Sum;


     System.out.print("What is your first name?: ");
    Name = Scanner.nextLine();

    System.out.print("How many jobs have you had?: ");
    TotalJobs = Scanner.nextInt();

    System.out.print("Enter income from job #1: ");
    Salary1 = Scanner.nextInt();

    System.out.print("Enter income from job #3: ");
    Salary2 = Scanner.nextInt();

    System.out.print("Enter income from job #3: ");
    Salary3 = Scanner.nextInt();
    Sum = Salary1 + Salary2 + Salary3;
    Average = Sum / TotalJobs;

     Largest = Salary1;
    Smallest = Salary1;

    if(Salary2 > Largest)
        Largest = Salary2;

    if(Salary3 > Largest)
        Largest = Salary3;

    if(Salary2 < Smallest)
        Smallest = Salary2;

    if (Salary3 < Smallest)
        Smallest = Salary3;

    System.out.println("Hello " + Name + "You've had " + TotalJobs + " jobs. " + "The highest paying job paid is " + Largest + ". The lowest paying job paid is "+ Smallest + ". The average is " + Average + ".");

but it wouldn't work cause it'll only ask the user three times, job 1, 2, and 3.

If I try,

for (int x = 0; x<TotalJobs; x++){ 
 System.out.print("How many jobs have you had?: "); 
 number = Scanner.nextInt();

I don't know how to get the highest/smallest/average from that stored value which would be 'number'.

Hope this will help You

    class SalaryCalculate{
    public static void main(String args[]){
    int totalJobs,jobcounter,maxSalary,minSalary,averageSalary=0;;
    int[] jobsincome;
    String name;
    Scanner sc= new Scanner(System.in);
    System.out.println("Enter your name");
    name=sc.nextLine();
    System.out.println("How many jobs you had");
    totalJobs= sc.nextInt();
    jobsincome= new int[totalJobs];
    for(int i=0;i<totalJobs;i++){
        jobcounter=i+1;
        System.out.println("Enter the income for your job "+jobcounter);
        jobsincome[i]=sc.nextInt();
        averageSalary=averageSalary+jobsincome[i];
    }
    jobsincome=average(jobsincome);
    maxSalary=jobsincome[totalJobs-1];
    minSalary=jobsincome[0];
    averageSalary=averageSalary/totalJobs;
    System.out.println("Hi "+name+" your min salary is "+minSalary+" max salary is "+maxSalary+" average salary is "+averageSalary);
    }
    public static int[] average(int jobsincome[]){
        int length=jobsincome.length;
        for(int i=0;i<length;i++){
            for(int j=i+1;j<length;j++){
                if(jobsincome[i]>jobsincome[j]){
                    int temp=jobsincome[j];
                    jobsincome[j]=jobsincome[i];
                    jobsincome[i]=temp;
                }
            }
        }
        return jobsincome;
    }
    }

Answer 2

Use an array.

Also only capitalize classes, not variables

System.out.print("How many jobs have you had?: ");
int totalJobs = scanner.nextInt();
int[] salaries = new int[totalJobs];

// Loop here 
// System.out.print("Enter income from job #"+x);
// salaries[x] = scanner.nextInt();

With this list, you can get the length directly and use separate loops for the sum, min, max. Or streams

With the sum and length, find an average

Answer 3

use an integer arraylist to keep salaries and loop through inputs

public static void main(String[] args)
{
    Scanner input = new Scanner(System.in);
    ArrayList<Integer> sallaries = new ArrayList<>();
    int TotalJobs;
    double average;
    String name;
    int largest;
    int smallest;

    System.out.print("What is your first name?: ");
    name = input.nextLine();


    System.out.print("How many jobs have you had?: ");
    TotalJobs = input.nextInt();

    for (int i= 0; i<TotalJobs ; i++){
        System.out.print("Enter income from job #"+(i+1)+" : ");
        sallaries.add(input.nextInt());
    }

    average = sallaries.stream().mapToInt(Integer::intValue).average().orElse(-1);

    largest = Collections.max(sallaries);
    smallest = Collections.min(sallaries);


    System.out.println("Hello " + name + "You've had " + TotalJobs + " jobs. " + "The highest paying job paid is " + largest + ". The lowest paying job paid is "+ smallest + ". The average is " + average + ".");
}
