In Java, the "break" statement is a control statement that is used to terminate the execution of a loop, a switch statement or a labeled block.
When used inside a loop (such as a for loop, while loop or do-while loop), the "break" statement causes the loop to immediately terminate and the program control is transferred to the statement immediately following the loop.
For example, consider the following code snippet:
for (int i = 1; i <= 10; i++) {
if (i == 5) {
break;
}
System.out.println(i);
}
In this code, the loop will iterate from 1 to 10, but when the value of i becomes 5, the "break" statement will be executed and the loop will be terminated. So, the output of this code will be:
1
2
3
4
When used inside a switch statement, the "break" statement causes the program control to exit the switch statement. If the "break" statement is not used, the program will continue executing the statements in the following cases until it reaches a "break" statement or the end of the switch block.
Overall, the "break" statement is a useful tool for controlling the flow of a program in Java.
