Errata, 5th Edition

• p136, Ch. 2: Exercise 2.21 StarFigure2 shows the wrong expected output. The output should be:
  

  Height 3	Height 6
  ////////\\\\\\\\ ////********\\\\ ****************	////////////////////\\\\\\\\\\\\\\\\\\\\ ////////////////********\\\\\\\\\\\\\\\\ ////////////****************\\\\\\\\\\\\ ////////************************\\\\\\\\ ////********************************\\\\ ****************************************

  (thanks to Megan Gustafson Melloy and Bill Iverson)
• p185, Ch. 2: The code for Projectile2.java has some negative symbols "-" that are erroneously appearing as "2". Line 7 of the program has 29.81 which should be -9.81 and line 31 has 22.0 which should be -2.0. (thanks to Eric Summer, APCS teacher at Da Vinci School, El Paso, TX)
• p387, Ch. 5: Exercise 5.4 randomX has a small typo. It says "prints a lines" when it should say "prints lines".
• p528, Ch. 7: Exercise 7.6 stdev has the wrong formula for the standard deviation due to a printing error. The formula should be:
  
  (thanks to James Livingston)
• p719, Ch. 10: Exercise 10.16 clump has minor formatting errors in its output. The last sentence of the problem description should be:
  
  Your method should change the list to store ["(four score)", "(and seven)", "(years ago)", "our"].
• p972, Ch. 15: Exercise 15.22 fromCounts should be more explicit about the fact that the method builds and returns a new ArrayIntList. The first two sentences of the exercise text should read, "Write a method called fromCounts that constructs and returns a new ArrayIntList of values given an existing ArrayIntList of counts. Assume that the ArrayIntList that is passed as a parameter stores a sequence of integer pairs that each indicate a count and a number."

Errors that occur only in the digital version:

• Ch.3G Ex.11: Says to modify your program to draw the "outputs" shown, but only one output is shown. There should be 3 outputs.
• Ch.9 Self Check 16: The Lake class is missing. It should in the problem description after the Ocean class.

Many thanks to Jonathan Sanders of the University of Washington for verifying and reporting several errors.
