일단 student class를 만들고 main을 만들었는데
student에서 tostring으로 name + age를 아웃풋 할 수 있게하고
main에서 s1 즉 name+age를 가진 값을 만들었는데 1번 프로그램으로하면 잘되는데
System.out.println("What is name");
Scanner sc1 = new Scanner(System.in);
name1 = sc1.next();
s1.setName("Name of Student : " + name1 + " , Age of Student : ");
System.out.println("What is age");
Scanner sc2 = new Scanner(System.in);
age1 = sc2.nextInt();
s1.setAge(age1);
부분을 loop안에 넣으면 아웃풋이
What is name
rick
What is age
13
What is name
anto
What is age
15
What is name
jeff
What is age
18
Student info:
Name of Student : Name of Student : jeff , Age of Student : , Age of Student : 18
Student info:
Name of Student : Name of Student : jeff , Age of Student : , Age of Student : 18
Student info:
Name of Student : Name of Student : jeff , Age of Student : , Age of Student : 18
Name is jeffage is 18
이렇게 되여 그러니깐 student info에 나오는 student이름이랑 나이가 마지막에 넣었던 값이에요
arrary ST[0],ST[1],ST[2]가 각각 나와야 하는데 왜 이렇게 나오는 거죠??
