Question

CSSSKL 142 Lab 3 (Part 2)

In this exercise you will write a method that takes a "Scanner" object from main and uses it to ask the user to input tow integers using the keyboard, sums their square roots, and prints a statement based on what bucket the result is in. The possible buckets are "Less than 10", "Between 10 and 20", "Between 20 and 30", and "Great than 30." Negative integers should be rejected with the appropriate message printed to the user. The method is named "sqrtSumBucketer", and it should work as follows:

If user enters 23 16, then:

sqrtSumBucketer ( input ); //Should print " Less than 10"

If user enters 2 999, then

sqrtSumBucketer ( input ); //Should print " Greater than 30."

If you have any doubts, please give me comment...

import java.util.Scanner;

public class CSSS142Lab3_2{

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter two integers: ");

int n1 = in.nextInt();

int n2 = in.nextInt();

sqrtSumBucketer(n1, n2);

}

public static void sqrtSumBucketer(int n1, int n2){

int sum = n1+n2;

double sqrtValue = Math.sqrt(sum);

if(sqrtValue<10)

System.out.println("Less than 10");

else if(sqrtValue>=10 && sqrtValue<=20)

System.out.println("Between 10 and 20");

else if(sqrtValue>20 && sqrtValue<=30)

System.out.println("Between 20 and 30");

else{

System.out.println("Greater than 30");

}

}
