Complete the seperateDuplicateChars() method in SeperateDuplicates.java as follows: - The method takes a String str as a parameter and returns a new String. - The returned String should be exactly like str, but any identical characters that appear in a consecutive way must be separated by hyphens "-". - You may ONLY use the following methods from the String class: charAt(), substring() and length(). Other than uncommenting the code, do not modify the main method in Seperate Duplicates.java. Sample runs provided below. Argument String str "Hello" "Bookkeeper" "Yellowwood door" "Chicago Cubs" Return String "Hel-lo" "Bo-ok-ke-eper" "Yel-low-wo-od do-or" "Chicago Cubs"

Step 1: Method 1
Here's the implementation for seperateDuplicatesChars() method:
CODE:
public static String seperateDuplicatesChars(String str) {
StringBuilder result = new StringBuilder();
result.append(str.charAt(0));
for (int i = 1; i < str.length(); i++) {
if (str.charAt(i) != str.charAt(i - 1)) {
result.append(str.charAt(i));
} else {
result.append("-").append(str.charAt(i));
}
}
return result.toString();
