     Scanner s=new Scanner(System.in); 
    System.out.println("Enter the Acc no:"); 
    int ano=s.nextInt(); 
    Class.forName("oracle.jdbc.driver.OracleDriver"); 
    Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE","scott","tiger"); 
    Statement st=con.createStatement(); 
    int n=st.executeUpdate("delete from ACCOUNT1 where ACCNO="+ano); 
    if(n==1) 
     System.out.println("account deleted succesfully"); 
    else 
     System.out.println("account doesnt exist"); 
    st.close(); 
    con.close(); 
    }
