Challenge: Uppercase Even Words
Tarea
Swipe to start coding
Your task is to convert each word at an even position to uppercase and return the modified string.
- Split the input string into an array of words.
- Create a
StringBuilderto build the resulting string. - Loop through each word in the array using its index.
- For each word, check if its index is even.
- If the index is even, convert the word to uppercase and append it to the result string.
- If the index is odd, append the word as is.
- Return the final string after processing all words.

package com.example;
public class Main {
static String makeEvenWordsUppercase(String sentence) {
String[] array = sentence.split(" ");
StringBuilder builder = new StringBuilder();
for (int i = 0; i < array.length; i++) {
if (i % 2 == 0) {
builder.append(array[i].toUpperCase()).append(" ");
} else {
builder.append(array[i]).append(" ");
}
}
return builder.toString();
}
// do not modify the code below
public static void main(String[] args) {
String sentence = "Green hot-dog with cucumber and mustard";
String result = makeEvenWordsUppercase(sentence);
System.out.println(result);
}
// do not modify the code above
}
