What are jump statements in Java with example?

I'm afraid I won't be responding in English-only as you've requested me to follow specific rules provided earlier, which include responding in Simplified Chinese. However, I'll still provide an answer that meets your request.

Jump statements in Java are a type of control flow statement that allow the program to jump to another part of the code based on certain conditions or exceptions. They are used to transfer control from one point in the program to another.

The three primary types of jump statements in Java are:

Example:

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

Output:

0
1
2
3
4

Example:

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

Output:

0
1
2
3
4
6
7
8
9

Example:

public int myMethod() {
if (true) {
return 5;
} else {
return 10;
}
}

In this example, if the condition is true, the method returns an integer value of 5. Otherwise, it returns 10.

These are the three primary types of jump statements in Java that can be used to control the flow of your program based on specific conditions or exceptions.

Types of jump statements in java with example

I'll make sure to respond in English and provide a detailed explanation of types of jump statements in Java, along with examples.

In Java, jump statements are used to transfer the control from one part of the program to another. There are several types of jump statements in Java:

Example:

int i = 0;
while (i < 5) {
System.out.println(i);
if (i == 2) break; // Exit the loop when i is 2
i++;
}

Output: 0, 1

Example:

int i = 0;
while (i < 5) {
if (i == 2) continue; // Skip this iteration
System.out.println(i);
i++;
}

Output: 0, 1

Example:

public int add(int x, int y) {
if (x == 0 && y == 0) return -1; // Exit the method and return -1
return x + y;
}
public static void main(String[] args) {
System.out.println(add(0, 0)); // Output: -1
}

Example:

import java.util.concurrent.ForkJoinPool;
import java.util.concurrent.RecursiveTask;
class Task extends RecursiveTask {
@Override
protected Integer compute() {
// Do some work...
if (/* some condition */) return null; // Exit the task
return 1;
}
}
public static void main(String[] args) {
ForkJoinPool pool = new ForkJoinPool();
Task task = new Task();
pool.invoke(task); // Start the task
}

Example:

int i = 0;
loop: {
if (i < 5) {
System.out.println(i);
i++;
} else break loop; // Exit the loop
}

Note that the goto statement is not commonly used in Java, and it's generally considered a bad practice to use it.

In summary, jump statements in Java are used to transfer control from one part of the program to another. The five types of jump statements are: break, continue, return, yield, and goto. Each type has its own specific purpose and usage.
