What is the job of this question mark "?" in java?

Answer 1

It's called 'ternary operator'.
The general form of writing the ternary operator is next:

condition ? true : false

For example:

System.out.println(5 > 2 ? "A" : "B");
will output "A"

and

System.out.println(5 > 7 ? "A" : "B");
will output "B"

There can be write more complicated kind of the ternary operator, but it doesn't change its matter.

I hope you easy understand example above.

Good luck 😉

Answer 2

The conditional operator, ?: , is a shorthand for an if-then-else construction that does one of two different things depending upon the result of a boolean expression.

The expression:

variable = booleanExpr ? value1 : value2;

has the same effect as:

if( booleanExpr ) {
    variable = value1;
} else {
    variable = value2;
}
