eclipse未编译的代码

Question

我尝试将Java程序连接到数据库和调用过程，没有语法错误或运行时错误，但是当编译器到达// st1并且我输入了第一个输入时，它会自动移到// st2（lastline ），它们之间的代码没有执行。因此，请帮助我解决此问题。

   public static void main(String args[]) throws 
   SQLException,ClassNotFoundException
{
    String driver = "oracle.jdbc.OracleDriver";
    String url,pass;
    url="jdbc:oracle:thin:@localhost:1521:prabhu";
    pass = "sysdb1";
    String user = "system";
    Class.forName(driver);
    Connection con = DriverManager.getConnection(url,user,pass);
    CallableStatement cs = con.prepareCall("{call increase(?,?)}");
    Scanner sc = new Scanner(System.in);  //st1
    Scanner sname = new Scanner(System.in);
    System.out.println("enter employee id and name whose salary you want to increase");
    int id=sc.nextInt();
    String name = sc.nextLine();
    cs.setInt(1, id);
    cs.setString(2, name);
    cs.execute();
    System.out.println("salary increased"); //st2
