在Groovy中返回多个参数

List<Integer> getNumbers() {
    def num1 = 10
    def num2 = 20
    return [num1, num2]
}
def result = getNumbers()
def num1 = result[0]
def num2 = result[1]
println "num1: $num1, num2: $num2"

Map<String, String> getUserInfo() {
    def name = "John Doe"
    def age = "25"
    return [name: name, age: age]
}
def result = getUserInfo()
def name = result.name
def age = result.age
println "name: $name, age: $age"

class Person {
    String name
    int age
    
    Person(String name, int age) {
        this.name = name
        this.age = age
    }
}

Person getPersonInfo() {
    def name = "John Doe"
    def age = 25
    return new Person(name, age)
}

def result = getPersonInfo()
def name = result.name
def age = result.age
println "name: $name, age: $age"
