The correct answer is: D. All of the above
The break statement is used to exit from a loop or switch statement. It can be used in any type of loop, including for, while, and do-while loops. It can also be used in a switch statement.
When the break statement is encountered, the control flow of the program immediately exits the loop or switch statement. The next statement after the loop or switch statement is executed.
For example, the following code shows how to use the break statement to exit from a for loop:
for (int i = 0; i < 10; i++) {
if (i == 5) {
break;
}
System.out.println(i);
}
This code will print the numbers from 0 to 4, because the break statement causes the loop to exit when i is equal to 5.
The following code shows how to use the break statement to exit from a while loop:
int i = 0;
while (i < 10) {
if (i == 5) {
break;
}
System.out.println(i);
i++;
}
This code will also print the numbers from 0 to 4, because the break statement causes the loop to exit when i is equal to 5.
The following code shows how to use the break statement to exit from a do-while loop:
int i = 0;
do {
if (i == 5) {
break;
}
System.out.println(i);
i++;
} while (i < 10);
This code will also print the numbers from 0 to 4, because the break statement causes the loop to exit when i is equal to 5.
The following code shows how to use the break statement to exit from a switch statement:
switch (x) {
case 1:
System.out.println("x is 1");
break;
case 2:
System.out.println("x is 2");
break;
case 3:
System.out.println("x is 3");
break;
default:
System.out.println("x is not 1, 2, or 3");
}
This code will print the message “x is 1” because the break statement causes the switch statement to exit when x is equal to 1.
The break statement is a powerful tool that can be used to control the flow of your program. It is important to use it carefully, however, because it can cause your program to behave unexpectedly if you are not careful.
