Groovy: Iterate over the list

You can iterate over a list in below ways.

b.   using each function

c.    Using eachWithIndex function

Using for..in loop

HelloWorld.groovy

primes = [2, 3, 5, 7, 11]

for (i in primes){
 print i + " "
}

Output

2 3 5 7 11

Using each function

HelloWorld.groovy

primes = [2, 3, 5, 7, 11]

primes.each{
 // 'it' is an implicit parameter corresponding to the current element
 print it + " "
}

Output

2 3 5 7 11

Using eachWithIndex function

HelloWorld.groovy

primes = [2, 3, 5, 7, 11]

primes.eachWithIndex{ it, i -> 
 println i + " " + it
}

Output
