Java continue Statement

In Java, the continue statement is used to skip the rest of the loop's current iteration and move on to the next iteration. It is often used with for, while, and do-while loops. In this tutorial, we will cover the basics of the continue statement in Java and how to use it with different types of loops.

Using continue with a for Loop

In a for loop, the continue statement can be used to skip the current iteration and move on to the next one. This is particularly useful when you want to perform an action only for specific elements in a collection or array.

Example:

public class ContinueExample {
    public static void main(String[] args) {
        for (int i = 1; i <= 10; i++) {
            // Skip even numbers
            if (i % 2 == 0) {
                continue;
            }
            System.out.println(i);
        }
    }
}

Output:

Using continue with a while Loop

Similarly, you can use the continue statement in a while loop to skip the current iteration and move on to the next one.

Example:

public class ContinueExample {
    public static void main(String[] args) {
        int i = 0;
        while (i < 10) {
            i++;
            // Skip even numbers
            if (i % 2 == 0) {
                continue;
            }
            System.out.println(i);
        }
    }
}

Output:

Using continue with a do-while Loop

The continue statement can also be used in a do-while loop to skip the current iteration and move on to the next one.

Example:

public class ContinueExample {
    public static void main(String[] args) {
        int i = 0;
        do {
            i++;
            // Skip even numbers
            if (i % 2 == 0) {
                continue;
            }
            System.out.println(i);
        } while (i < 10);
    }
}

Output:

In summary, the continue statement in Java is used to skip the rest of the current iteration in a loop and move on to the next one. It can be used with for, while, and do-while loops to control the flow of the loop based on specific conditions.

Using continue statement in loops in Java

The continue statement is used to skip the rest of the loop body and move to the next iteration.

for (int i = 1; i <= 5; i++) {
    if (i == 3) {
        continue; // Skip iteration when i is 3
    }
    System.out.println("Iteration: " + i);
}

Examples of Java continue statement

Here's an example where the continue statement is used to skip odd numbers in a loop:

for (int i = 1; i <= 10; i++) {
    if (i % 2 != 0) {
        continue; // Skip odd numbers
    }
    System.out.println("Even number: " + i);
}

Skipping iterations with Java continue statement

In this example, the continue statement is used to skip iterations where the value is less than 5:

for (int i = 1; i <= 10; i++) {
    if (i < 5) {
        continue; // Skip iterations with i < 5
    }
    System.out.println("Iteration: " + i);
}

Nested loops and continue statement in Java

The continue statement can be used in nested loops to skip the current iteration of the inner loop and move to the next iteration of the outer loop.

for (int i = 1; i <= 5; i++) {
    for (int j = 1; j <= 3; j++) {
        if (j == 2) {
            continue; // Skip inner loop iteration when j is 2
        }
        System.out.println("i: " + i + ", j: " + j);
    }
}

Infinite loop prevention with continue in Java
The continue statement can be used to prevent infinite loops by adding a condition that allows the loop to skip to the next iteration.
```
int count = 0;
while (count < 5) {
    if (condition) {
        count++;
        continue; // Skip to the next iteration
    }
    // Loop body
}
```

Java labeled continue statement

Java supports labeled continue statements, allowing you to specify which loop to continue when dealing with nested loops.

outerLoop:
for (int i = 1; i <= 3; i++) {
    for (int j = 1; j <= 3; j++) {
        if (j == 2) {
            continue outerLoop; // Continue the outer loop
        }
        System.out.println("i: " + i + ", j: " + j);
    }
}
