Add the following lines to StringExplorer to see for yourself that indexOf behaves as specified: int notFoundPsn = sample. indexOf("slow");

System. out. println("sample. indexOf(\"slow\") = " + notFoundPsn);

Read the description of indexOf(String str, int fromIndex). Notice that there are two indexOf methods, however, they have different parameters. What are the differences between indexOf(String str)text annotation indicator and indexOf(String str, int fromIndex)text annotation indicator? The substring method also occurs twice. Read the description so you understand the difference between the two.

Review the methods in the following table. Notice the parameters and return type of each method. Look at the method descriptions in the String API. Once you understand what each method does, add lines to StringExplorer that illustrate each of the methods in the table. Include comment lines that state each method you are demonstrating as shown in the two examples.

Think about a recent customer service experience - either positive or negative. write a brief summary of that experience. now think about those four characteristics we look for in customer service representatives. how did the representative in your example stack up? write down your answer and give specific examples.

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
