Bodiless loops in Java

Concept

• In Java, a loop may not have an associated body, as a null statement is syntactically valid.

Utility

• Bodyless loops can be used for operations that are completely handled in the loop expression.

-Example of a loop without a body

• The example below adds the numbers 1 to 5 using a for loop without a body:

class Empty3 {
    public static void main(String args[]) {
        int i;
        int sum = 0;
        // soma os números até 5
        for (i = 1; i 



<p>The program output is: Sum is 15</p>

<p><strong>Loop analysis</strong></p>

<p>The sum is performed completely within the for loop expression.<br>
The iteration expression sum += i++ does the addition and increment of i:<br>
sum += i++;</p>

<p><strong>Breaking down the expression</strong></p>

• This expression can be understood as two parts:
• sum = sum + i; - Add i to sum. i++; - Increments i.

Importance

• Instructions of this type are common in professional Java programs.
• Understanding and breaking down these expressions makes understanding the code easier.
