Question 1. My friend concatenates. Should I report him to the authorities?

1.a. No. It's only illegal during the winter months

1.b. Yes, but not until I sell the story to TMZ.com first

1.c. No. All he's doing is pasting two strings together in a program

Concatenation is just another word for pasting, joining, melding, or otherwise connecting two strings together. It uses the + and += operators.

Question 2. Why is the word String capitalized, while int and others are not?

2.a. String is a full word, but int ain't

2.b. Like all objects in Java, String has a capitalized name

2.c. Poor quality control at Sun Microsystems

The types of objects available in Java are all capitalized, which is the main reason variable names have a lowercase first letter. It makes it harder to mistake them for objects.

Question 3. Which of the following characters puts a single quote in a string?

3.a. <quote>

3.b. \'

3.c. '

The single backslash is what begins one of the special characters that can be inserted into strings.
