JAVA generator overloading, instance generation, return method, improved for statement, ArrayList object array generation, array value added

1. Dog1.java – Class to be used when generating instances DogTest1.java – Class to create and print instances through Dog1 (object generation using ArrayList)

* Dog1 class // default generator (if not generated during generator overload), which receives and stores puppy names and dog types. Since the public Dog1(){};// member variable is declared private, a method to extract and deliver values through getter must be created.getter & setters // String形式の値を返すshowDogInfo() メソッドpublic String showDogInfo() {return name + “, ” +type; }Dog1.java Class

Dog1 showDogInfo() Method

// The basic form of the first contact for statement // The size of the array in the dogList is access via size ////// access to each index value via get(i);i++){System.out.println(dogList.get(i).showDogInfo()); }DogTest1.java 클래스
