Chapter 9, Problem 4FTE

Explanation of Solution

Given statements:

//Tokenize a string that is delimited

//with semicolons. The string has 3 tokens

String str = "one;two;three"; //Line 1

String tokens = str.split(";"); //Line 2

System.out.println(tokens); //Line 3

Error in the given statement:

Tokenizing string:

  • It is a process of breaking down the string into the components called tokens.
  • The string can be split using the split method which breaks the string using the delimiter for breaking it.
  • The split method is used for the tokenizing the string.

Error #1:

The “tokens” variable must reference the array of tokens that is returned by the method “split ()” in “Line 2”. So the statement must be rewritten as:

String[] tokens = str...

True or FalseWhen you call a string object’s Split method, the method divides the string into two substrings and returns them as an array of strings.
Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
public String firstAndLast(String str) { //declare and create your first char   //declare and create your second char   //return your first and last char as a String      }
