Edhesive in JAVA Write a method that takes a String parameter. If the String has a double letter (i. e. contains the same letter twice in a row) then it should return true. Otherwise, it should return false. This method must be named hasRepeat() and have a String parameter. This method must return a boolean.

The method is an illustration of loops and conditional statements.

Loops are used for repetitive operations, while the execution of a conditional statement is based on its truth value.

The hasRepeat() method in Java, where comments are used to explain each line is as follows:

   //This defines the hasRepeat() method

   public static boolean hasRepeat(String str){

       //This initializes the previous character

       char prevC = ' ';

       //This iterates through the characters of the string str

       for(int i = 0; i<str.length();i++){

           //This gets the current character

           char currC = str.charAt(i);

           //If the current character and the previous character are the same

           if(currC == prevC){

               //Return true

               return true;

           }

           //Assign the current character to the previous character

           prevC = currC;

       }

       //Return false, it the string contains no repetitive character

       return false;

   }

At the end of the method, the program returns true or false.
