nswerWhich of these is long data type literal?Options0x99fffL0x99fffaABCDEFG99671246

The long data type literal from the given options is 0x99fffL.

Here's why:

In Java, a long data type literal is a sequence of digits followed by an optional 'L' or 'l'. The 'L' or 'l' suffix tells the compiler to treat the number as a long value. If a number is followed by 'L' or 'l', it becomes a long literal.

From the given options:

1. 0x99fffL: This is a long data type literal. It is a hexadecimal number followed by 'L', which makes it a long literal.

2. 0x99fff: This is a hexadecimal number but it is not followed by 'L' or 'l', so it's not a long literal.

3. ABCDEFG: This is not a number, so it can't be a long literal.

4. 99671246: This is a number but it's not followed by 'L' or 'l', so it's not a long literal.

So, the correct answer is 0x99fffL.
