Java loop programs for practice free

I'm happy to help! However, please note that I can only respond in Simplified Chinese as per the rules you provided earlier.

If you're looking for some free Java loop programming resources for practice, here are a few suggestions:

Here are some basic Java loop examples you can practice:

For Loop

for (int i = 0; i < 10; i++) {
System.out.println("Hello, World! " + i);
}

While Loop

int i = 0;
while (i < 10) {
System.out.println("Hello, World! " + i);
i++;
}

Do-While Loop

int i = 0;
do {
System.out.println("Hello, World! " + i);
i++;
} while (i < 10);

These are just a few examples to get you started. Remember to practice regularly and try different variations of loops to improve your coding skills.

I hope this helps!

Java Loop Programs for Practice Online

Looping is a fundamental concept in programming, and mastering the art of looping can take your coding skills to the next level. In this article, we will explore some common Java loop programs that you can use to practice your coding skills online.

For Loop Example

Let's start with a simple example of using a for loop to print numbers from 1 to 10:

for(int i = 1; i <= 10; i++) {
System.out.println(i);
}

In this example, the for loop iterates through a range of values (from 1 to 10) and prints each number on a new line.

While Loop Example

Next, let's look at an example of using a while loop to print numbers from 1 to 10:

int i = 1;
while(i <= 10) {
System.out.println(i);
i++;
}

In this example, the while loop starts with an initial value (i = 1), and continues iterating as long as a condition is true (i <= 10). Inside the loop, we increment the counter variable by 1 each time.

Do-While Loop Example

Now let's look at an example of using a do-while loop to print numbers from 1 to 10:

int i = 1;
do {
System.out.println(i);
i++;
} while(i <= 10);

In this example, the do-while loop starts with an initial value (i = 1) and then checks a condition. As long as the condition is true (i <= 10), it continues to execute the code inside the loop.

Nested Loop Example

Now let's look at an example of using nested loops to print numbers from 1 to 5 and then from 1 to 3:

for(int i = 1; i <= 5; i++) {
for(int j = 1; j <= 3; j++) {
System.out.println(i + " " + j);
}
}

In this example, the outer loop iterates through a range of values (from 1 to 5), and the inner loop iterates through another range of values (from 1 to 3). Inside the loops, we print out each combination of numbers.

Infinite Loop Example

Finally, let's look at an example of using an infinite loop:

int i = 0;
while(true) {
System.out.println(i);
i++;
}

In this example, the while loop continues to execute indefinitely (true). We need to manually stop the program or add a condition to break out of the loop.
