ct answerLiterals in java must be appended by which of these?OptionsLDIL and I

The correct answer is L and D. In Java, when you have a long literal, you append it with an 'L' or 'l'. For example, long num = 15000L;. Similarly, for a double literal, you append it with a 'D' or 'd'. For example, double num = 100.5D;. However, it's important to note that for integer literals, you don't need to append them with 'I' or 'i'.

Literals in Java are basic representations of integer, floating-point, and character data types. In Java, integer literals are of int data type by default. To specify long data type we append 'L' or 'l' at the end. Similarly, for floating-point literals, we append 'D' or 'd' for double and 'F' or 'f' for float.

So, the correct answer is 'L' and 'D'.
