Question

Write a Java program that will ask the user for his/her salary (numerical integer salary) and then convert this numerical salary into income class. The following is a guideline to the income class used. The numeric range within parenthesis maps to the preceding class. If the user gave you a number greater than 700,000 or less than 10,000, you should print a message that the input is invalid. In this code, DO NOT USE && OPERATOR. You should use if-else.

Income Mapping

Very high (200,000 to 700,000)

High (150,000 to 199,999)

Upper Middle (100,000 to 149,999)

Middle (70,000 to 99,999)                                                                                                                                           

Lower Middle (50,000 to 69,999)       

Low (20,000 to 49,999)     

Very Low (10,000 to 19,999)  

Sample input and output:

Please input your salary: 85000

Your income class is a middle.

Answer 1

Java code:

import java.util.Scanner;
public class Main{
   public static void main(String[] args){
   Scanner input=new Scanner(System.in);
   //initializing salary
   int salary;
   //asking for salary
   System.out.print("Please input your salary: ");
   //accepting salary
   salary=input.nextInt();
   //checking if the salary is greater than 700000
   if(salary>700000)
   //printing Input is invalid
   System.out.println("Input is invalid");
   //checking if the salary is greater than 200000
   else if(salary>=200000)
   //printing Very high
   System.out.println("Your income class is a Very high.");
   //checking if the salary is greater than 150000
   else if(salary>=150000)
   //printing High
   System.out.println("Your income class is a High.");
   //checking if the salary is greater than 100000
   else if(salary>=100000)
   //printing Upper Middle
   System.out.println("Your income class is a Upper Middle.");
   //checking if the salary is greater than 70000
   else if(salary>=70000)
   //printing Middle
   System.out.println("Your income class is a Middle.");
   //checking if the salary is greater than 50000
   else if(salary>=50000)
   //printing Lower Middle
   System.out.println("Your income class is a Lower Middle.");
   //checking if the salary is greater than 20000
   else if(salary>=20000)
   //printing Low
   System.out.println("Your income class is a Low.");
   //checking if the salary is greater than 10000
   else if(salary>=10000)
   //printing Very Low
   System.out.println("Your income class is a Very Low.");
   else
   //printing Input is invalid
   System.out.println("Input is invalid");
   }
}
