<p>In this article, you will learn how to use continue construct and continue labels in Kotlin.</p>
<p><span style="display: inline !important; float: none; background-color: #ffffff; color: #2c3338; cursor: text; font-family: 'Noto Serif',Georgia,'Times New Roman',Times,serif; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; line-height: 1.2em; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">Sometimes it is useful to force an early iteration of a loop. That is, you might want to continue running the loop but stop processing the remaining code in its body for this particular iteration. In such case we can use <span style="color: #0000ff;"><strong>continue</strong> </span>statement.</span></p>
<h3><span style="color: #000080;"><strong>Kotlin continue example</strong></span></h3>
<p><span style="display: inline !important; float: none; background-color: #ffffff; color: #2c3338; cursor: text; font-family: 'Noto Serif',Georgia,'Times New Roman',Times,serif; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; line-height: 1.2em; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">The continue statement is used to skip the iteration of the nearest enclosing loop (for, while, and do&#8230;while loop).</span></p>
<p>Basically, continue is used to repeat the loop for a specific condition. It skips the remaining statements and continues with the next iteration of the loop.</p>
<h4><span style="color: #0000ff;"><strong>Syntax</strong></span></h4>
<p>Syntax of <span style="color: #008000;"><strong>continue</strong> </span>in for loop:</p>
<pre>for (iteration through iterator) {
 <strong><span style="color: #008000;">//codes</span></strong>
 if (test-expression) {
 continue
 }
 <strong><span style="color: #008000;">//codes</span></strong>
}</pre>
<p>If<strong><span style="color: #0000ff;"> test-expression </span></strong>is evaluated to <span style="color: #008000;"><strong>true</strong></span>, <strong><span style="color: #008000;">continue</span> </strong>statement is executed which skips the remaining statements inside the loop and continues with the next iteration of the loop.</p>
<h4><span style="color: #0000ff;"><strong>Example</strong></span></h4>
<p>The below program will print even numbers between 1 to 10.</p>
<pre>fun main(args: Array<;String>;) {

 for (n in 1..10) {

 if (n % 2 != 0)
 <span style="color: #008000;"><strong>continue</strong></span>

 print(" $n ")

 }
}</pre>
<h4><span style="color: #0000ff;"><strong>Output</strong></span></h4>
<pre>2 4 6 8 10</pre>
<h4><span style="color: #0000ff;"><strong>Example explained:</strong></span></h4>
<p>In the above example, when n = { 1, 3, 5, 7, 9 } :</p>
<ul>
<li><span style="color: #008000;"><strong>If</strong></span> condition <strong><span style="color: #0000ff;">( n % 2 ! = 0 )</span></strong> is checked<strong>, </strong>yields <strong><span style="color: #008000;">true</span>.</strong>Then<strong>, </strong>continue statement is executed, which skips the execution of <strong><span style="color: #008000;">print(&#8221; $n &#8220;)</span></strong> statement.</li>
</ul>

<h3><span style="color: #000080;"><strong>Kotlin Labeled continue example</strong></span></h3>
<p>In Kotlin, <span style="color: #008000;"><strong>labeled</strong> </span>continue is used to skip the iteration of the desired loop when certain condition is satisfied. It can be done with the help of <span style="color: #008000;"><strong>labels</strong></span>.</p>
<p><strong><span style="color: #008000;">Label</span> </strong>starts with an identifier which is followed by <strong>‘ : ‘</strong>. e.g.-<span style="color: #008000;"><strong> inner@ , outer@</strong> </span>etc.</p>
