Explain The ?  operator in Java ?

The value of a variable frequent depends on whether a particular boolean expression is or is not true and on nothing else. For example one general operation is setting the value of a variable to the maximum of two quantities. In Java you might write

if (a > b) {
max = a;
}
else {
max = b;
}

Setting a single variable to one of two states based on a single condition is like a general use of if-else in which a shortcut has been devised for it, the conditional operator, ?:. By using the conditional operator you can rewrite the above instance in a single line such as this:

max = (a > b) ? a : b;

(a > b) ? a : b; is an expression that returns one of two values, a or b. The condition, (a > b), is tested. If it is true the first value, a, is returned. If it is false, the second value, b, is returned. Whenever value is returned is dependent on the conditional test, a > b. The condition can be any expression that returns a boolean value.
