Answer 1

 –Xmx1G # incorrect: en dash
 -Xmx1g # correct: hyphen-minus

JVM arguments considered hyphen to consider JVM arguments. If you are using MAC book, It could be easily delusional for view

A hyphen, -, separates words in phrases, as in “least-used product” and is used for line breaks in books and other matter.

An em dash, —, is used to set off a phrase—one in the middle of the sentence—that’s not quite a parenthetical, but it isn’t so germane as to be set off by commas. It’s also used as a sort of pause to emphasize something—something important at the end of a sentence.

An en dash, –, separates ranges for dates, numbers, and quantities—like 9–5 and January–August. It’s also used for certain kinds of connections, directions, and contrasts, such as standing in for “versus” in Lincoln–Douglas debates or in place name pairing like Alsace–Lorraine, where both are separate places being referred to together.
