Question

Consider the examples below:

A. a string.
B. 'a string'.
C. "a string".
D. "1234".
E. integer.

Which could be the value of a Java variable of type String?

a. A and B.
b. B and E.
c. B and C.
d. C and D.

Answer 1

In Java, the values that could be Strings are those enclosed in double quotes. Hence, the correct examples of String values are 'a string' enclosed in double quotes and "1234".

Step-by-step explanation:

The question asks which of the given examples could be the value of a Java variable of type String. In Java, a String is a sequence of characters enclosed in double quotes. Therefore, the correct answer to the question is "c. B and C".

• B. 'a string': This is not a valid String in Java, as single quotes are used for a char type, which can only hold one character.
• C. "a string": This is a correct example of a String in Java as it is enclosed in double quotes.
• D. "1234": This is also a valid String in Java; although the characters are digits, they are enclosed in double quotes, making it a String.
• E. integer: The word 'integer' without quotes is not a valid Java String, as it would be seen as a variable name or a type.
