Java do while loop

Created By: chatGPT

Java's do while loop is a control flow statement that allows code to be executed repeatedly based on a given boolean condition. Unlike the while loop, the do while loop guarantees that the code inside the loop will be executed at least once because the condition is checked after the execution. Here's how you can use it:
do {
    // code block to be executed
} while (condition);
In this structure, the code block is executed first, and then the condition is evaluated. If the condition is true, the loop will repeat. If it is false, the loop will terminate. Here is a simple example of a do while loop that counts from 1 to 5:
int count = 1;
do {
    System.out.println(count);
    count++;
} while (count <= 5);

In this code:

  • We declare an integer variable count initialized to 1.
  • The loop will print the value of count and increment it by 1.
  • The loop continues until count is greater than 5. As a result, this loop will output: 1 2 3 4 5

This demonstrates how the do while loop works by executing at least once before checking the condition.

Output:
1
2
3
4
5
