list1 = list1.leftShift(11)
println "list1 : $list1"

list1.add(13)

list1.addAll([17, 19])
println "list1 : $list1"

list1 = list1.plus(29)
println "list1 : $list1"

Output

list1 : [2, 3, 5]
list1 : [2, 3, 5, 7]
list1 : [2, 3, 5, 7, 11]
list1 : [2, 3, 5, 7, 11, 13]
list1 : [2, 3, 5, 7, 11, 13, 17, 19]
list1 : [2, 3, 5, 7, 11, 13, 17, 19, 23]
list1 : [2, 3, 5, 7, 11, 13, 17, 19, 23, 29]
