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
