Groovy: Default arguments to a method

Groovy support default arguments to a method.

Example

def printMe(String name, int age = 23, String organization="ABC Corporation"){

       println "name : $name, age : $age, organization : $organization"

}

As you see the definition of printMe method, I specified 23 as default value to age and "ABC Corporation" is the default value for the argument organization. If you do not provide any values to age and organization, then the default values are used.

HelloWorld.groovy

def printMe(String name, int age = 23, String organization="ABC Corporation"){
 println "name : $name, age : $age, organization : $organization"
}

printMe("Krishna")
printMe("Krishna", 30)
printMe("Krishna", 30, "Umbrella Labs")

Output

name : Krishna, age : 23, organization : ABC Corporation

name : Krishna, age : 30, organization : ABC Corporation

name : Krishna, age : 30, organization : Umbrella Labs

Note

No mandatory parameter can be defined after a default parameter
