In the Java programming language, the break statement is used to exit or terminate the execution of a loop or a switch statement. It is primarily used to control the flow of the program and allows you to prematurely exit a loop or skip the remaining code in a switch statement.
The break statement can be used in the following contexts:
- Loop statements (such as
for,while, ordo-while): When thebreakstatement is encountered within a loop, the loop is immediately terminated, and the program execution continues with the next statement after the loop.
for (int i = 0; i < 10; i++){ if (i == 5){ break; // terminates the loop when i reaches 5}System.out.println(i);}
i becomes 5, the break statement is encountered, and the loop terminates.- Switch statements: The
breakstatement is used to exit the switch block. When abreakstatement is encountered within a switch case, the program execution jumps to the end of the switch block.
switch (day)
{
case 1: System.out.println("Monday"); break; case 2: System.out.println("Tuesday"); break; case 3: System.out.println("Wednesday"); break; default: System.out.println("Invalid day"); }In the above example, when day is 3, the "Wednesday" message is printed, and then the break statement is encountered, causing the program to exit the switch block.Note that if a break statement is omitted in a switch case, the program will continue executing the following cases until a break statement is encountered or until the end of the switch block is reached. This behavior is known as "fall-through" and can be intentionally used in some cases.
Overall, the break statement is a control flow statement in Java that allows you to exit loops or switch statements prematurely and continue with the next statement after the loop or switch.
