How is the java "and" symbol typed?

This article introduces the relevant knowledge of "java" and "how to type symbols". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

How did the java "and" symbol come out?

The "and" symbol in java can be typed using the Shift + number 7 on the keyboard. (not the number 7 on the keypad)

In Java, & & can be used as the operator of logical and to represent logical and (and). When the result of the expression on both sides of the operator is true, the whole operation result is true, otherwise, as long as one side is false, the result is false.

Examples of use:

Int a = 1 * * string b = "abc"; if (a & & b) {System.out.println ("both an and b are true")}

Knowledge expansion: the difference between & and &

"&" regardless of whether the first judgment condition is true or not, both conditions before and after the logical operator will be judged.

"&", the first condition is not true, the latter conditions are not judged; the first condition is established, continue to judge the second condition.
