  3. What is Helloworld. (with no space between the two words)? • This would be the output of the following: s.o.p. (“Hello” + “world.”); Basics 1 Back to Board

  4. What is constant? • Variables that will not change in your program should be of this type. Basics 2 Back to Board

  5. What is %? • This operator returns the remainder of a division problem. Back to Board Basics 3

  6. What is “ , ( , {? • These three symbols require a closing symbol if you want to use them without generating an error. Back to Board Basics 4

  7. What is print? • This method prints data on one continuous line. Back to Board Output1

  8. What is logical? • An error in a program that works but produces the incorrect result is this type of error? Output 2 Back to Board

  9. What is after the string is printed? • When using the println method at what point does the program return down a space. Output 3 Back to Board

  10. What is 2? • How many lines would be in our output from the following call to print? System.out.println System.out.print System.out.print System.out.println Back to Board Output 4

  11. What is string concatenation? • This allows us to split a character string that does not fit on one line of the program. String Literal 1 Back to Board

  12. What is 24 and 45 concatenated: 2445? • What will be the result of the following string concatenation: System.out.println (“24 and 45 concatenated:” + 24 + 45); String Literals 2 Back to Board

  13. What is \“? • This escape sequence provides a double quotation mark around a string. Back to Board String Literal 3

  14. What is compareTo? • Programmers use this to tell whether one string comes before another alphabetically. Back to Board String Literals 4

  19. What is a mathematical/arithmetic expression? • This type of expression is a combination of operators and operands. Back to Board Data 1

  20. What is 11? • The solution for the following expression would be what? result = 10 + (8 / 2 )%3 Data 2 Back to Board

  21. What is an integer? • When you divide an integer by an integer your answer is this type of number. Data 3 Back to Board

  22. What is 2.0? • What would the answer be to the following formula: Int x = 30 Int y = 12 Double z = x/y Data 4 Back to Board

  23. What is a cast? • We must use this when committing a narrowing conversion. Random 1 Back to Board
