meaning of while loop in Java

In Java programming language,while Is a loop statement that repeatedly executes a block of code based on specified conditions.

Syntax:

<code class="java">while (condition) {
    // 循环体
}</code>

How it works:

• First, the while statement is evaluated Conditions in brackets (condition).
• If the condition is true, execute the code block in the loop body.
• After executing the loop body, the program returns to the condition and evaluates it again.
• If the condition is still true, continue executing the loop body.
• If the condition becomes false (that is, false), the loop stops.

Example:

The following example shows how to print the numbers 1 to 10 using a while loop:

<code class="java">int i = 1;
while (i <= 10) {
    System.out.println(i);
    i++;
}</code>

In this example:

• Variable i is initialized to 1.
• while The loop evaluates the condition i <= 10.
• As long as the condition is true, the loop body will be executed and the number i will be printed.
• After each loop, i will be incremented by 1.
• When i becomes 11, the condition becomes false and the loop stops.
