Chapter 9.3, Problem 9.15CP
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.
- The method “trim” denotes a built-in function that eliminates leading as well as trailing spaces in string.
Given code:
String str1 ="William ";
String str2 ="the";
String str3 ="Conqueror";
System.out.println(str1.trim() + str2.trim() +
str3. trim());
Explanation:
- The strings are been stored in variables “str1”, “str2” and “str3”.
- The strings are been trimmed using “trim()” method.
- The resultant strings are concatenated using “+” operator.
- The result of concatenation is been displayed.

Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."
