仅按一种类型创建多个 Java 对象
java programming java8object oriented programming
您可以轻松创建对象列表。请考虑以下示例，我将创建一个 Employee 对象数组并在 for 循环中打印其详细信息。
import java.lang.reflect.InvocationTargetException;
import java.util.ArrayList;
import java.util.List;
public class Tester implements Cloneable {
private int data;
public int getData() {
return data;
}
public void setData(int data) {
this.data = data;
}
public Tester(int data){
this.data = data;
}
public static void main(String[] args) {
List<Tester> testerList = new ArrayList<Tester>();
testerList.add(new Tester(1));
testerList.add(new Tester(2));
testerList.add(new Tester(3));
testerList.add(new Tester(4));
for(Tester tester : testerList){
System.out.println(tester.getData());
}
}
}
