@tiasangmoi92
tiasangmoi92bạn nào pro xem giúp mình cái bài này với sao mình gán số a trực tiếp thì vòng for chạy đúng mà mình gán bằng cách nhập từ bàn phím thì phần nhập ở trong vòng for tự bỏ đi 1 lần lặp.
phần chạy nó hiện như sau

run:
nhap vao so a =
2
nhập vao sinh viên thứ 1
nhập vao sinh viên thứ 2
pham hoang
sinh viên thứ 1 là :
sinh viên thứ 2 là :pham hoang
build successful (total time: 11 seconds)

[mirandarkerr]

mình muốn hỏi là ở đoạn này :
int tuoi;
string ten;
scanner nhapdulieu = new scanner(system.in);

system.out.print("nhập tên: ");
ten = nhapdulieu.nextline();

system.out.print("nhập tuổi: ");
tuoi = nhapdulieu.nextint();

mình muốn nhập thêm địa chỉ và mình đã thêm như sau :

int tuoi;
string ten.diachi;
scanner nhapdulieu = new scanner(system.in);

system.out.print("nhập tên: ");
ten = nhapdulieu.nextline();

system.out.print("nhập tuổi: ");
tuoi = nhapdulieu.nextint();

system.out.print("nhập địa chỉ: ");
diachi = nhapdulieu.nextline();

system.out.println("
tên vừa nhập:" + ten);
system.out.println("tuổi vừa nhập: " + tuoi);
system.out.println("địa chỉ vừa nhập:" + diachi);

//đoạn in đậm là đoạn mình thêm vào

khi chạy ctr thì sau khi nhập tuổi ctr tự động kết thúc và in ra kết quả như này :

tên vừa nhập : abc.
tuổi vừa nhập : 25
dia chi vừa nhập :

nghĩa là ctr bỏ qua luôn bước nhập địa chỉ mà in ra nguyên cái câu : địa chỉ vừa nhập .

theo mình nghĩ chắc có vấn đề ở nextint của dòng nhập tuổi , khi mình thử cho đoạn nhập địa chỉ lên trước nhập tuổi thì ctr cho nhập như btg .
vậy các bạn có thể xem giúp mình xem muốn nhập địa chỉ sau khi nhập tuổi thì sửa code như thế nào cho đúng
