JAVA——20.创建对象数组

【数组】一组类型相同的数据

public class student{
               private String name;
               public student(){//不带参数的构造方法

               }

               public student(String name){
                   this.name=name;
               }
               public String getname(){
                   return name;
               }
               public static void main(String[] args){
                 student[] students=new student[3];//声明数组：student类[]->初始化数组：长度,初始化每一个元素
                 students[0]=new student("jack");
                 students[1]=new student("mary");
                 students[2]=new student("wendy");
                 for(int i=0;i<3;i++){
                         System.out.println(students[i].getname());
                  }
               }

}
