The break statement is used to stop current iteration of loop or end Switch-case block. The switch statement is similar to a series of IF statements on the same expression. This means that the other relational operators such as greater than are rendered unusable in a case.
There's no need to preemptively save the result in a variable either. The switch statement is Java’s multi-way branch statement. Without having to worry about the function being re-evaluated for every case. I think this fact needs a little bit more attention, so here's an example:
Java switch statement code#
The difference between a series of if statements and the switch statement is that the expression you're comparing with, is evaluated only once in a switch statement. The switch statement executes one or several code blocks, similar to the else if statement, depending on which of its so-called case statements are true. This is listed in the documentation above, but it's a bit tucked away between the paragraphs.
