Answer #1

1) Answer is option (a). an object definition, containing the data function elements necessary to create an object
why because, the class is described as one or more objects.object is an instance of the class. so the option 'a' is the answer.

2)Answer is option (c).method class
why because Method class gives data about a single method in a class.

3)Answer is option (c). Boolean
why because, Boolean variables consist of only two values, ie, true or false.
other options do not belong to this question. because double datatype consists of floating-point numbers, string consist of variables, and int datatype consists of integers.

4)Answer is option (c).double
why because, as we said earlier that, double datatype consists of floating-point numbers. other options do not belong to this question. because Boolean variables consist of only two values, ie, true or false, string consist of variables, and int datatype consist of integers.

5)Answer is option (d). char
why because, char datatype consists of characters with single-byte or multibyte.other options are not belongs to this question. because double datatype consists of floating-point numbers, string consists of variables, and int datatype consists of integers.

6)Answer is option (d). char
why because, char datatype consists of characters with single-byte or multibyte, and it is enclosed within single quotes.other options do not belong to this question. because int datatype consists of integers, Boolean variables consist of only two values, ie, true or false, string consists of variables.

7)Answer is an option (a). string
why because, string consist of variables, other options do not belong to this question. because char datatype consists of characters with single-byte or multibyte, double datatype consists of floating-point numbers, and int datatype consists of integers.

8)Answer is option (d). int
why because int datatype consists of integers. other options do not belong to this question. because Boolean variables consist of only two values, ie, true or false, double datatype consists of floating-point numbers, and string consists of variables.

9)Answer is option (c). boolean
why because, Boolean variables consist of only two values, ie, true or false.
other options do not belong to this question. because double datatype consists of floating-point numbers, string consist of variables, and int datatype consists of integers.

10)Answer is option (a).to hold values in the memory of the computer
why because variables are stored on the stack area or heap area and local variables are stored on the stack area.so other options do not belong to this question.
