• No output

Consider the following code segment.

System.out.print("AP");

System.out.println("CS");

System.out.print("A");

Consider the following code segment.

System.out.print(I do not fear computers. ); // Line 1

System.out.println(I fear the lack of them.); // Line 2

System.out.println(--Isaac Asimov); // Line 3

The code segment is intended to produce the following output but may not work as intended.

I do not fear computers. I fear the lack of them.

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 line 1, print should be changed to println.

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

Consider the following code segment.

System.out.print(*); // Line 1

System.out.print("*"); // Line 2

System.out.println(); // Line 3

System.out.println("*"); // Line 4

The code segment is intended to produce the following output, but may not work as intended.
