APCS UNIT 1

Consider the following code segment.

What is printed as a result of executing the code segment?

• Hello!!!

• Hello System.out.println!!!

• Hello

  !!!

• Hello System.out.println

  !!!

• Nothing is printed because the text "System.out.println" cannot appear inside a print statement.

  
  

Which of the following changes can be made so that the code segment produces the intended output?

• Changing print to println in line 1 only

• Changing print to println in line 2 only

• Changing print to println in line 3 only

• Changing print to println in lines 2 and 3 only

• Changing print to println in lines 1, 2, 3, and 4

Which line of code, if any, causes an error?

• Line 1

• Line 2

• Line 3

• Line 4

• The segment works as intended

What is printed as a result of executing the code segment?

Which change, if any, can be made so that the code segment produces the intended output?

• In line 1, print should be changed to println.

  
  

• In lines 2 and 3, println should be changed to print.

  
  

• The statement System.out.println() should be inserted between lines 2 and 3.

  
  

• In lines 1, 2, and 3, the text that appears in parentheses should be enclosed in quotation marks.

  
  

• No change is needed; the code segment works correctly as is.

  double d = 1.5;

  final double c = 0.0;

• final double pi = 3.14159;

  final double d = 1.5;

  final double c = 0.0;
