我被分配去做一个程序，用户可以在整个大学（每门课程）的每个部分输入学生。我似乎无法在for循环中显示用户输入的值，（我决定声明某个课程每年的数组）我只是java的新手，对不起，如果它不可读

    String[] name1a = new String [2000];
 System.out.println("\nDo you want to add students or view student?\nA.ADD\nB.DISPLAY");
                      System.out.println("Enter the letter of your choice");
                     view=input.next().charAt(0);

                    if (view=='a' || view=='A')
                     {System.out.println("\nThe following are the section/s for "+yearlvl.get(yrlvl-1));
                     for (int i = 0; i < Sections1a.size(); i++) {
                     System.out.println((i+1)+"."+Sections1a.get(i));
                      }//section names display
                     System.out.println("Enter the number of the section");
                     int picksection1a=input.nextInt()*60;
                     input.nextLine();
                     System.out.println("How many students do you want to add?");
                     int studnum1a=input.nextInt();
                     input.nextLine();

                     for (int counter=picksection1a; counter<(picksection1a+studnum1a); counter++)
                      {  System.out.println("Student #"+(counter+1)+": ");
                         name1a[counter]=input.nextLine();

                      }//for counter
                     }//if view A
                     else if (view=='B' || view=='b')
                        { System.out.println("\nThe following are the section/s for "+yearlvl.get(yrlvl-1));
                     for (int i = 0; i < Sections1a.size(); i++) {
                     System.out.println((i+1)+"."+Sections1a.get(i));
                      }//section names display
                     System.out.println("Enter the number of the section");
                     int viewsection1a=input.nextInt()*60;
                     input.nextLine();
                        int dec=1;
                     for (int display=viewsection1a ; display<(viewsection1a+60); display++)
                     {
                         System.out.println("Student #"+dec+": "+name1a[display]);


//it only shows null,the values I inputted doesn't show up


                         }
                        }//else if view b

我希望程序显示60个值。 （我的意思是输入的值，其余60个空值）
