The break statement is required in the default case of a switch selection structure?

Answer 1

Ends the case statement. Without it, any code after where the break; is supposed to be will get executed as well until it does encounter a break; or the end of the switch.

Code Example:

char cTest = 'a';

switch(cTest) {

case 'a':

/* Code here gets executed. */

case 'b': /

/* Code here gets executed. */

case 'c':

/* Code here gets executed. */

break;

case 'd':

/* Code here won't be executed. */

default:

/* Code here won't be executed. */

}

Answer 2

The break statement takes the flow of control out of the switch statement. Recall that each case element in the switch statement acts like a "goto" statement so, without the break statement, execution would simply continue to the next case. If that is what you intend, then don't use the break statement. Often, however, that is not what is intended, so break statements are necessary.

Answer 3

In Java, if you don't want to break out of the switch code-block you could 'return' to exit the method with the switch statement.

char ch = getChar();

switch(ch) {

case 'a':

// do something

break;

case 'b':

// do something else

return;

....

}

// break resumes here

Answer 4

False. Java does not require break statements anywhere in a switch structure. You may, however, get a warning.

Answer 5

The break statement when used in a switch takes the control outside the switch.
The control falls through all the cases unless the break statement is given.

Answer 6

The break statement is used to close the switch statement. If you do not have the break statement the switch statement would keep going on.

Answer 7

When the flow of execution passes through a break statement within a switch, execution passes to the statement that follows the switch.
