The correct answer is: C. Literal type constant
A literal type constant is a constant that has a specific data type. This data type is determined by the form of the literal. For example, the literal 1 is an integer literal, and the literal “Hello” is a string literal.
However, there are some cases where a literal type constant can be forced to assume a data type other than the one its form indicates. This can happen when the literal is used in a context where a different data type is expected. For example, the following code will compile and print “1”:
int x = 1;
System.out.println(x);
However, the following code will not compile:
String x = 1;
System.out.println(x);
This is because the compiler expects the right-hand side of the assignment operator to be a string, but the literal 1 is an integer. To fix this, we can use a cast:
String x = (String) 1;
System.out.println(x);
The cast tells the compiler to treat the literal 1 as a string, and the code will compile and print “1”.
In conclusion, a literal type constant is a constant that has a specific data type. This data type is determined by the form of the literal. However, there are some cases where a literal type constant can be forced to assume a data type other than the one its form indicates. This can happen when the literal is used in a context where a different data type is expected.
