Question

Complete the class LoopyText. The constructor has been completed and provided to you in Codecheck. • public LoopyText(String theText) Constructs an object of Loopy Text and stores the Text inside the object. The parameter the Text is a string with zero or more words separated by single spaces. • public String getEverySecondCharacter() Returns a string consisting of every other character, starting with the character at index 0. If the string is the empty string return the empty String. public int uppercaseCount() Returns the number of uppercase letters in the text. public String firstLetters () Returns a string consisting of the first character of every word in the string. If the string is the empty string return the empty String.

Given code:

/**
* Provides some methods to manipulate text
*
*/
public class LoopyText
{
private String text;
  
/**
* Creates a LoopyText object with the given text
* @param theText the text for this LoopyText
*/
public LoopyText(String theText)
{
text = theText;
}
  
//Your methods here
}

Given tester code:

/**
* Tests the methods of LoopyText.
* @author Kathleen O'Brien
*/
public class LoopyTextTester
{
public static void main(String[] args)
{
LoopyText loopy = new LoopyText("Java for All");
System.out.println(loopy.getEverySecondCharacter());
System.out.println("Expected: Jv o l");
  
loopy = new LoopyText("Today is the First Day of the Rest of your LIFE");
System.out.println(loopy.getEverySecondCharacter());
System.out.println("Expected: Tdyi h is a fteRs fyu IE");
  
loopy = new LoopyText("");
System.out.println(loopy.getEverySecondCharacter());
System.out.println("Expected: ");
}
}

Answer 1

LoopyText.java

public class LoopyText
{
private String text;
  
/**
* Creates a LoopyText object with the given text
* @param theText the text for this LoopyText
*/
public LoopyText(String theText)
{
text = theText;
}
  
//Your methods here

public String getEverySecondCharacter() {
   String s = "";
   for(int i=0;i<text.length();i++) {
       if(i%2 == 0) {
           s = s + text.charAt(i);
       }
   }
   return s;
}
}

LoopyTextTester.java

/**
* Tests the methods of LoopyText.
* @author Kathleen O'Brien
*/
public class LoopyTextTester
{
public static void main(String[] args)
{
LoopyText loopy = new LoopyText("Java for All");
System.out.println(loopy.getEverySecondCharacter());
System.out.println("Expected: Jv o l");
  
loopy = new LoopyText("Today is the First Day of the Rest of your LIFE");
System.out.println(loopy.getEverySecondCharacter());
System.out.println("Expected: Tdyi h is a fteRs fyu IE");
  
loopy = new LoopyText("");
System.out.println(loopy.getEverySecondCharacter());
System.out.println("Expected: ");
}
}

Output:

Jv o l
Expected: Jv o l
Tdyi h is a fteRs fyu IE
Expected: Tdyi h is a fteRs fyu IE

Expected:
