Exam 9: Text Processing and More About Wrapper Classes

When you are writing a program with String objects that may have unwanted spaces at the beginning or end of the strings, use this method to delete them.

The term ________ commonly is used to refer to a string that is part of another string.

This is the process of converting a wrapper class object to a primitive type.

Which of the following statements will print the maximum value an int variable may have?

Look at the following code. Integer myNumber; MyNumber = 5; Which of the following is TRUE about the second statement?

To convert the double variable, d = 543.98, to a string, use the following statement:

What is the value of str after the following code has been executed? String str; String sourceStr = "Hey diddle, diddle, the cat and the fiddle"; Str = sourceStr.substring(12,17);

The process of breaking a string down into tokens is known as what?

To convert the string, str = "285.74" to a double, use the following statement:

Look at the following code: Integer myNumber = new Integer(5); Int var = myNumber; Which of the following is TRUE about the second statement?

What will be the value of matches after the following code has been executed? Boolean matches; String str1 = "The cow jumped over the moon."; String str2 = "moon"; Matches = str1.endsWith(str2);

What is the term used for the character that separates tokens?

This character is one that appears at the end, or right side, of a string, after the non-space characters:

Look at the following statement: StringBuilder str = new StringBuilder(25); What will the StringBuilder constructor do?

What will be printed after the following code is executed? String str = "abc456"; Int m = 0; While ( m < 6 ) { If (!Character.isLetter(str.charAt(m))) System.out.print( Character.toUpperCase(str.charAt(m))); M++; }

Sometimes a string will contain a series of words or other items of data separated by spaces or other characters. In programming terms, items such as these are known as what?

The no-arg constructor for a StringBuilder object gives the object enough storage space to hold this many characters.

What would be the results of executing the following code? StringBuilder str = new StringBuilder("Little Jack Horner "); Str)append("sat on the "); Str)append("corner");

What will be the tokens in the following statement? String str = "red$green&blue#orange"; String[] tokens = str.split("[$&#]");

The following statement correctly creates a StringBuilder object. StringBuilder str = "Caesar Salad";
