Groovy introduction: 1) no accessors method 2) gString 3) accessing object 4) equality operator not referring to memory address extra: can change the value to make wrong assertion just to show groovy trace

Introduction1.groovy

class Person {
    String name
    int age
}
 
//no accessors method
 
Person person = new Person()
person.name = "goku"
println "helloo ${person.name}"
assert person.name == "goku"
assert person["name"] == "goku"
 
person = new Person(name:"gohan")    //passing constructor value
assert person.name == "gohan"
println "helloo ${person.name}"
