How to use "continue" in groovy's each loop

Question

I am new to groovy (worked on java), trying to write some test cases using Spock framework. I need the following Java snippet converted into groovy snippet using "each loop"

Java Snippet:

List<String> myList = Arrays.asList("Hello", "World!", "How", "Are", "You");
for( String myObj : myList){
    if(myObj==null) {
        continue;   // need to convert this part in groovy using each loop
    }
    System.out.println("My Object is "+ myObj);
}

Groovy Snippet:

def myObj = ["Hello", "World!", "How", "Are", "You"]
myList.each{ myObj->
    if(myObj==null){
        //here I need to continue
    }
    println("My Object is " + myObj)
}

question from:https://stackoverflow.com/questions/41465691/how-to-use-continue-in-groovys-each-loop

Answer 1

Either use return, as the closure basically is a method that is called with each element as parameter like

def myObj = ["Hello", "World!", "How", "Are", "You"]
myList.each{ myObj->
    if(myObj==null){
        return
    }
    println("My Object is " + myObj)
}

Or switch your pattern to

def myObj = ["Hello", "World!", "How", "Are", "You"]
myList.each{ myObj->
    if(myObj!=null){
        println("My Object is " + myObj)
    }
}

Or use a findAll before to filter out null objects

def myList = ["Hello", "World!", "How", "Are", null, "You"]
myList.findAll { it != null }.each{ myObj->
    println("My Object is " + myObj)
}
