  6. 2. • What is printed? char a = ‘b’; char b = ‘a’; System.out.print(a);

  7. 3. • What is the value of number? double number = (1/3)*3;

  8. 4. • What is the value of number? int number = 3+2/5;

  9. 5. • What is the value of number? • int number = (int) 5.7;

  10. 6. • What word denotes the answer to a method?

  11. 7. • What line of Java declares and creates an object in the Student class with your name?

  12. 8. • Suppose I want to write a method to tell whether or not a number is positive. • What would the input and output types be?

  13. 9. • Suppose I want to write a method that takes a letter and whether or not it should be upper case and computes the new letter. • What should the input and output types be?

  14. 10. • What is special about a variable declared with the word “final”?

  24. 20. • What is the value of x at the end of the code? int x = 3; int y = 5; x = y; y = y+1;

  25. 21. • Suppose the Tiger class has this behavior: public int countTeeth() What line of code calls the countTeeth behavior on the Tiger tony?

  26. 22. • Suppose the Tiger class has this behavior: • public void grabMice(int mice) • What line calls the grabMice behavior on the Tiger tony for 3 mice?

  27. 23. What is the error? public int mystery(double a, double b){ if (a<b){ return a; } return b; }

  28. 24. • What does this method do? public int mystery(int a){ int answer = a%100; return answer; }

  29. 25. • What is the error? public int mystery(int a, int b){ if(a<b){ return a; } else if (a>=b){ return b; } }

  30. 26. What is x? int a = 3;int b = 5;int x;if (a<b){ x = 0;}else if (b<10){ x = 1;}else{ x = 2;}

  31. 27. What is x? int a = 3;int b = 5;int x;if (a<b){ x = 0;}if (b<10){ x = 1;}else{ x = 2;}

  32. 28. • Find and fix the error: arc(100,100,100,100, PI, 0);

  33. Write a method The above formula calculates a person’s BMI given their height in centimeters and weight in kilograms. Write a method to calculate a person’s BMI given their height and weight, but the weight is given in grams. (1 kilogram = 1000 grams). public double bmi(double wt, double ht){

  34. Write a method You need to write a program to help out your weekend business doing lawn care. You really need to buy $15 bags of grass seed, but if any money is left over, you also need some $2 bags of mulch. Write a method that takes as input how much money you have and prints how many bags of grass seed and mulch I can buy. For example, if I have 52 dollars, I can buy 3 bags of seed (that’s $45) and 3 bags of mulch ($6 more). public void purchaseOrder(int dollars) The line System.out.println(x) prints the value of the variable x.
