java 的是switch语句报错

Question

这是代码

import java.io.*;
public class Score2 {
	public static void main(String args[])throws IOException
	{
		BufferedReader input=new BufferedReader(new InputStreamReader(System.in));
			System.out.println("Please input s=");
			String str=input.readLine();
			int s=Integer.parseInt(str);
			int flag=s/10;
			System.out.println(flag);
			swtich(flag)
			{
				case 0:
				case 1:
				case 2:
				case 3:
				case 4:
				case 5:
				case 6:System.out.println("不及格");break;
				case 7:System.out.println("及格");break;
				case 8:System.out.println("中");break;
				case 9:System.out.println("良");break;
				case 10:System.out.println("优");break;
				default:System.out.println("Error!");break;
			}
	}
}

这是显示的错误

    Syntax error on tokens, Label expected instead
    Syntax error on token "case", assert expected
    Syntax error on token "case", assert expected

仔细看看 switch拼错了
