Program Plan Intro
String class:
- The “String” class provides a number of methods that examines for a string inside of a string.
- The term “substring” refers to a string that denotes another string’s part.
- The “startsWith” method would determine whether calling string of object begins with a specific substring.
- The method returns “true” if string begins with specified substring, it returns “false” otherwise.
- The “endsWith” method would determine whether calling string would end with a specified substring.
- The method returns “true” if string ends with specified substring, it returns “false” otherwise.
- The “regionMatches” method would determine whether specified regions for two strings match.
- The first argument of this method can be “true” or “false” that indicates whether a case-insensitive comparison could be performed.
StringBuilder class:
- The “StringBuilder” class is same as “String” class except that contents of “StringBuilder” objects could be changed.
- It provides several methods that “String” class does not have.
- The “append” method accepts an argument that might be a primitive data type.
- It appends a string representation to contents of calling object.
- The “insert” method accepts two arguments, an integer that specifies position in string of calling object as well as value to be inserted.
- The “replace” method replaces the occurrences of one character with another character.
- The “toString” method converts a “StringBuilder” object in to a regular string.

How does the StringBuilder class’s replace method differ from the String class’s replace method?
True or False: The String class’s replace method can replace individual characters, but cannot replace substrings.
You will be able to pinpoint the position of the substring in which you are interested by using one of the string objects.

- In the class String, the substring method inserts a String into another String. -True or -Falsearrow_forwardName format: You must use String object and not StringBuffer or StringBuilder. Many documents use a specific format for a person's name. Write a program that take one Line as an input. Example: Scanner input = new Scanner(System.in); System.out.println(“Enter firstName middleName lastName separated by at least one blank, It may have more than one blank separating firstName middleName lastName."); Input sample : Pat Silly Doe || Note these are separated by at least one blank. String line = input.nextLine() Ex: If the input is: Pat Silly Doe the output is: Doe, P.S. If the input has the form: firstName lastName the output is: lastName, firstInitial. Ex: If the input is: Julia Clark the output is: Clark, J. Please submit the .java source file and the sample run in a text file.

Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output.arrow_forward
