Question: Write a static method called acronym that takes as a parameter a String containing a phrase and that returns an acronym for the phrase. For
Write a static method called "acronym" that takes as a parameter a String containing a phrase and that returns an acronym for the phrase. For example, the following call:
acronym("self contained underwater breathing apparatus")
should return "SCUBA".
The acronym is formed by combining the capitalized first letters of each word in the phrase. Words in the phrase will be separated by some combination of spaces or tabs. There might be extra spaces at the beginning or end of the phrase. The String will not contain any characters other than spaces, and letters, and is guaranteed to contain at least one word.
import java.util.*;
public class Acronym {
public static void main(String[] args) {
System.out.println(acronym(" automatic teller machine ")); // "ATM"
System.out.println(acronym("personal identification number")); // "PIN"
System.out.println(acronym("computer science")); // "CS"
System.out.println(acronym("merry go round")); // "MGR"
System.out.println(acronym("All my Children")); // "AMC"
System.out.println(acronym("Troubled Assets Relief Program")); // "TARP"
System.out.println(acronym("quite confusing punctuation ")); // "QCP"
System.out.println(acronym(" loner ")); // "L"
}
// *** Your method code goes here ***
} // End of Acronym class

There are 3 Steps involved in it
To solve this problem you need to write a static method called acronym inside a Java class which takes a string input representing a phrase and returns the acronym formed by the capitalized first letter of each word Heres how you can proceed with the solution StepbyStep Solution 1 Trim Extra Spaces Use the trim method to eliminate any leading or trailing spaces from the phrase 2 Split the Phrase Split the phrase into individual words Since the words can be separated by spaces or tabs use a regular expression that accounts for both s The s matches any whitespace character and the ensures it matches one or more times allowing it to handle multiple spaces and tabs 3 Extract and Capitalize First Letters Create an empty StringBuilder or String that will hold the acronym Iterate over the array of words extract the first character of each word convert it to uppercase using toUpperCase and append it to your acronym string 4 Return the Acronym Once all words have been processed and their first letters capitalized and concatenated convert the StringBuilder to a String and return ...
