  29. Define: Index Arrays – 100 (solution) The Index is the location of the element in the array. Other names for index are position and subscript.

  30. Define: Element Arrays – 200 (solution) The Element is the actual item stored in a position in the array.

  31. The way to find out how many elements are in the array Arrays – 300 (solution) arrayName.lengthwhere arrayName is the name of the array

  32. Write the code to copy the elements of array a into array b Arrays – 400 (solution) for(int i=0; i<a.length; i++) { b[i] = a[i];}

  33. Write code to find the middle of array a and replace it with an asterisk “*” Arrays – 500 (solution) a[a.length/2] = “*”;

  34. 2 * 5 + 5 / 2 Math - 100 (solution) 10 + 2 = 12

  35. 2 % 5 + 5 / 2 Math – 200 (solution) 2 + 2 = 4

  36. (2 * 2 + 6) % 3 Math – 300 (solution) ( 4 + 6) % 3 ( 10 ) % 3 = 1

  37. (7 + 2) * 5 + 1 Math – 400 (solution) 9 * 5 + 1 45 + 1 = 46

  38. 4 + (2 + 5 * 3) % 2 Math – 500 (solution) 4 + (2 + 15 ) % 2 4 + ( 17 ) % 2 4 + 1 = 5

  39. int average = 93;System.out.println(“My average is ” + (double) average); Printing/Comments – 100 (solution) My average is 93.0

  40. System.out.println(“\tI like Apples\n A LOT!”); Printing/Comments – 200 (solution) I like ApplesA LOT!

  41. System.out.println(“\\*This is not\n a comment *\\”); Printing/Comments – 300 (solution) \*This is not a comment *\

  42. System.out.println(“\\\n I am ready \n for break. \\\\ ”); Printing/Comments – 400 (solution) \ I am ready for break. \\

  43. System.out.println(“\\\“Happy \n Birthday!*\””); Printing/Comments – 500 (solution) \”Happy Birthday!*”

  44. Casting Vocab – 100 (solution) Casting is used to temporarily change data types:int score = (int) 83.4; yields 83double dScore = (double) 83; yields 83.0

  45. Modulus Vocab – 200 (solution) Modulus is used to get the remainder when dividing 2 numbers. In Java, % is used:int rem = 9 % 2; yields 1

  46. Concatenation Vocab – 300 (solution) Concatenation is used to combine strings together:String name = “John”;int grade = 87;String s = name + “ made a “ + grade;

  47. SNUL Vocab – 400 (solution) SNUL is an acronym which is useful when sorting strings:Spaces / special charactersNumbersUppercase charactersLowercase charactersSpaces are lower than numbers, etc.

  48. Instantiation Vocab – 500 (solution) Instantiation is used to create a new object:Student stu = new Student(“Tom”, 100);Robot karel = new Robot(1,1,West,0);

  49. Zero out an array Code – 100 (solution) for(int i =0; i<a.length; i++) { a[ i ] = 0; }

  50. Sum of an array Code – 200 (solution) int sum = 0;for(int i =0; i<a.length; i++) { sum += a[ i ]; }
