Java Break and Continue

Java break and continue statements are used to control the flow of a loop.

The break statement is used to exit a loop prematurely, while the continue statement is used to skip an iteration of a loop.

Break Statement

The break statement is used to exit a loop prematurely and transfer control to the next statement outside the loop.

The break statement can be used with for, while, and do-while loops.

Here's an example of how to use the break statement in a for loop:

for (int i = 0; i & lt; 10; i++) {
    if (i == 5) {
        break;
    }
    System.out.println(i);
}

In this example, the loop will iterate 10 times, but when the value of i is equal to 5, the loop will exit and the next statement outside the loop will be executed.

The output of this code will be:

0
1
2
3
4

It's important to use the break statement carefully, as it can make your code hard to understand and maintain if not used appropriately.

Continue Statement

The continue statement is used to skip an iteration of a loop and proceed to the next iteration.

The continue statement can be used with for, while, and do-while loops.

Here's an example of how to use the continue statement in a for loop:

for (int i = 0; i & lt; 10; i++) {
    if (i == 5) {
        continue;
    }
    System.out.println(i);
}

In this example, the loop will iterate 10 times.

When the value of i is equal to 5, the current iteration of the loop will be skipped and the next iteration will begin.

The output of this code will be:

0
1
2
3
4
6
7
8
9

It's important to use the continue statement carefully, as it can make your code hard to understand and maintain if not used appropriately.

Labeled Break and Continue

In Java, you can use labels to provide a name for a specific loop or switch statement.

You can then use the labeled break or continue statement to exit or skip iterations of the labeled loop.

Here's an example of how to use a labeled break statement:

outer: for (int i = 0; i & lt; 3; i++) {
    for (int j = 0; j & lt; 3; j++) {
        if (j == 1) {
            break outer;
        }
        System.out.println("i = " + i + "; j = " + j);
    }
}

In this example, the labeled break statement with the label outer will exit both the inner and outer loops.

The output of this code will be:

i = 0; j = 0

And here's an example of how to use a labeled continue statement:

outer: for (int i = 0; i & lt; 3; i++) {
    for (int j = 0; j & lt; 3; j++) {
        if (j == 1) {
            continue outer;
        }
        System.out.println("i = " + i + "; j = " + j);
    }
}

In this example, the labeled continue statement with the label outer will skip the current iteration of the outer loop.

The output of this code will be:

i = 0; j = 0
i = 1; j = 0
i = 2; j = 0

It's important to use labeled break and continue statements carefully, as they can make your code hard to understand and maintain if not used appropriately.

In conclusion, Java break and continue statements provide a way to control the flow of a loop.

The break statement is used to exit a loop prematurely, while the continue statement is used to skip an iteration of a loop.

Labeled break and continue statements allow for specific loops to be exited or skipped.

It's important to use these statements carefully, as they can make your code hard to understand and maintain if not used appropriately.
