java - 扫描仪输入新的扫描仪(文档)； <--------错误；预期

Question

我正在尝试进行编译，但似乎收到一条错误消息，指出我在具有;的行上缺少;。我还查看了代码，自己也看不到错误。我希望你能指出正确的方向:)

import java.io.*;
import java.util.*;


public class marks
{

    private String  asses;
    private int  mark;


    public marks()
    {


    }


    public void createFile() throws Exception
    {
        File doc;
        doc = new File ("marks.txt");
        if(!doc.exists()){
            doc.createNewFile();
            System.out.println("A New File Has been Created");
          }
    else {
     System.out.println ("File Already Exists");
    }
 }

 public void enterMarks()
 {
   Scanner input new Scaner(doc); <---------- Error ; expected 

   while (input.hasNext()){
       String asses = input.next();
       int mark = input.nextInt();
       System.out.println( asses +" "+ mark);
    }
 }
}
