write a method in class  String  that returns the reserved version of the current  String(in java)  here's the method signature public static int ceiling (double num) {      return num <=0? (int) num : (int) num +1; }

Java allows for methods to be chained together. Consider the following message from the captain of a pirate ship: String msg1 = " Maroon the First Mate with a flagon of water and a pistol! ";   We want to change the message to read the message msg1:   String msg2= “Maroon the Quartermaster with a flagon of water.”   Three changes need to be made to adjust the string as desired:   Trim the leading and trailing whitespace. Replace the substring First Mate with Quartermaster. Remove "and a pistol!" Add a period at the end of the sentence. A “chaining1” method which will apply in sequence 4 operations to perform the above. We will use the trim, replace, and substring methods, in this order. Thus the chaining1 method will receive a string msg1 and return a string msg2. Make sure msg2 is printed. A “chaining2” method which will apply the 4 operations above in one single statement. Thus the chaining2 method will receive a string msg1 and return as string msg2. Make sure msg2 is printed

Computer Programming Java  Write a method named FirstHalf that receives a String parameter named word and then returns the first half of the string. You are guaranteed as a precondition that word has an even length greater than 1.
