Question

This was a quiz that I submitted earlier in the semester but I had not received full points due to a coding mistake. Below, I will provide the instructions and the code that needs to be changed in order for the program to work. Any place that has a "// Student Code Here" or "// Test Your Methods Here" must be changed accordingly.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------INSTRUCTIONS:Step 1Fill in the doubleOrNothing method, which takes an int as a parameter. If the number is less than 100, return that number doubled. Otherwise, return zero.For example, passing 4 to this method would return 8, but passing 104 to this method would return 0.Step 2Fill in the formatPercentmethod, which takes a double as a parameter that represents a percent value between 0 and 1. This method returns a String that is the percentage between 0 and 100 percent, with one place following the decimal before a '%'.For example, passing the double '.85' would return the string "85.0%".Step 3Fill in the everyOtherChar method, which takes a String parameter called word*. This method returns an int which computes the sum of the ASCII values of *every other* character in the parameter word, starting with the first character.For example, passing the word "yam" into the method would tally the ASCII value of the characters 'y' and 'm', which have ASCII values of 121 and 109 respectively, so the method would return 230.Test Your MethodsTest your methods by calling them within main. You may run your program in Develop mode as many times as you would like, but you may only submit your program once.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------CODE:public class quiz1 { // Step 1 public static int doubleOrNothing(int num) {e // student code here } // Step 2 public static String formatPercent(double percent) { // student code here } // Step 3 public static int everyOtherChar(String word) { // student code here } public static void main(String [] args) { // test your methods here! }}

Answer:

The methods is completed as follows

See attachment for .java source file

Program starts here

import java.util.*;

public class quiz1

{

public static int doubleOrNothing(int num)

{

 if(num<100)

 {

  num*=2;

 }

 else{

  num = 0;

 }

 System.out.println(num);

 return num;

}

public static String formatPercent(double percent)

{

 percent*=100;

 System.out.println(percent+"%");

 return percent+"%";

}

 

public static int everyOtherChar(String word)

{

 char first = word.charAt(0);

 char last = word.charAt(word.length() - 1);

 int ascii = (int)first + (int)last;

 System.out.print(ascii);

 return ascii;

}

public static void main(String [] args)

{

 //Testing doubleOrNothing method

 int num;

 Scanner input = new Scanner(System.in);

 System.out.print("Enter any integer number: ");

 num = input.nextInt();

 System.out.print("Result of doubleOrNothing method\n:");

 doubleOrNothing(num);

 

 //Testing formatPercent method

 double percent;

 System.out.print("Enter any number between 0 and 1: ");

 percent = input.nextDouble();

 System.out.print("Result of formatPercent method\n:");

 formatPercent(percent);

 

 //Testing everyOtherChar method

 String word;

 System.out.print("Enter any string: ");

 word = input.next();

 System.out.print("Result of everyOtherChar method\n:");

 everyOtherChar(word);

}

}
