Hello @margam mamatha
,
Try to use this code:
Apex Class:
public class MyIterable implements Iterable<String> {
Private List<String> strings;
// Constructor to initilize the list of strings
public MyIterable(List<String> strings)
{
this.strings = strings;
}
// Implementing the iterator method
public Iterator<String> iterator(){
return strings.iterator();
}
}
Test Class:
@IsTest
public class MyIterableTest {
@IsTest
static void testIterableForLoop(){
// Create a list of strings
List<String> strings = new List<String> {'Hello', 'World'};
// Create an Instance of MyIterable
MyIterable myIterable = new MyIterable(strings);
// Use a for loop to iterate over the MyIterable instance
for(String str: myIterable){
//Print each string to the debug log
System.debug(str);
}
}
}
After saving the Apex Class and Test Class, click "Run Test".
