In Java, underscores can be used to separate groups of digits in an integer literal for better readability. Therefore, the correct way to write 100,000 as an int literal in Java is 100_000. Option A is a valid integer 100,000 but not a valid integer literal. Option B is not a valid integer literal; it uses a dot instead of an underscore to separate the digits. Option D is also a valid integer literal but with a suffix 'L' indicating a long type, not an int type.
