Question

1. Write a Java program to compute the income after tax of an employee based on the following rule of tax rate. Assuming the salary is $22000, display the tax and the income after tax.

• 12% if salary ≥ 25,000
• 5% if salary < 10,000
• Otherwise 8% will be applied

2. Write a Java program to compute and display the sum of the numbers that can be both divisible by 6 and 8 from 1 to 500.

3. Suppose there is a list of 15 integers: 38, 15, 29, 148, 72, 64, 116, 99, 284, 223, 117, 202, 63, 114, 96. Write a program that can i) display the even integers in ascending order and display their sum; ii) display the odd integers in ascending order and display their sum. (Hint: Use Arrays class to sort array items)

1Answer:

code:

import java.lang.*;
import java.util.*;
class Tax{
   public static void main(String[] args){
       Scanner sc = new Scanner(System.in);
       System.out.print("Enter the amount : ");
       int amount = sc.nextInt();
       double tax, income;
       if(amount >= 25000){
           tax = (12 * amount) / 100.0;
       }else if(amount < 10000){
           tax = (5 * amount) / 100.0;
       }else{
           tax = (8 * amount) / 100.0;
       }
       System.out.println("Tax is : " + tax);
       System.out.println("Income is : " + (amount - tax));
   }
}

output:

import java.util.*;
class Sum{
   public static void main(String[] args){
       int sum = 0;
       int i;
       for(i=1;i<=500;i++){
           if((i % 6 == 0) && (i % 8 ==0)){
               sum = sum + i;
           }
       }
       System.out.println("The sum is : " + sum);
   }
}

3Answer:

code:

import java.lang.*;
import java.util.*;
public class EvenOdd{
public static void main(String[] args){
int arr[] = new int[15];
int i, evenSum = 0, oddSum = 0;
Scanner sc = new Scanner(System.in);
System.out.println("Enter the array elements : ");
for(i=0;i<15;i++){
arr[i] = sc.nextInt();
}
Arrays.sort(arr);
System.out.println("Even");
for(i=0;i<15;i++){
if(arr[i] % 2 == 0){
evenSum = evenSum + arr[i];
System.out.println(arr[i]);
}
}
   System.out.println("Even sum is : " + evenSum);
   System.out.println("odd");
    for(i=0;i<15;i++){
if(arr[i] % 2 != 0){
    oddSum = oddSum + arr[i];
System.out.println(arr[i]);
}
}
System.out.println("Odd sum is : " + oddSum);
}
}

output:
