Groovy: List all the properties of a class

Using meta field ‘properties’ of an instance, you can list all the properties of a class.

HelloWorld.groovy

class Employee {
 String name
 int id
}

Employee emp1 = new Employee()
employeeProperties = emp1.properties.keySet();

println "Properties of the class Employee are : "
for(prop in employeeProperties){
 println "$prop"
}

Output

Properties of the class Employee are :

class

id

name

Let’s add one field ‘organization’ (Filed is not a property) and confirm that it is not part of employee properties.

HelloWorld.groovy

class Employee {
 String name
 int id
 
 public String organization
}

Employee emp1 = new Employee()
employeeProperties = emp1.properties.keySet();

println "Properties of the class Employee are : "
for(prop in employeeProperties){
 println "$prop"
}

Output

Properties of the class Employee are :

class

id

name
