java小白 这段代码显示这个错误 不太明白 求大神指教！
import java.util.Scanner;
public class Operators {
public static void main(String[] args){
Scanner s = new Scanner(System.in);
//整数操作
System.out.print("Enter integer 1>2 ");
int i1 = s.nextInt();
System.out.print("Enter integer 2>4 ");
int i2 = s.nextInt();
System.out.println(i1+i2);
System.out.println(i1%i2);
System.out.println(i1<<i2);
System.out.println(i1>>i2);
System.out.println(i1>>>i2);
System.out.println(i1&i2);
//……
//小数操作
System.out.print("Enter decimal 1>2.4");
double d1 = s.nextDouble();
System.out.print("Enter decimal 2> 5.6");
double d2 = s.nextDouble();
System.out.println(d1+d2);
System.out.println(d1*d2);
System.out.println(d1-d2);
System.out.println(d1%d2);
//……
//boolean操作
System.out.print("Enter boolean 1 > true");
boolean b1 =s. nextBoolean();
System.out.print("Enter boolean 2 > False");
boolean b2 = s.nextBoolean();
System.out.println(b1&b2);
System.out.println(b1|b2);
System.out.println(b1^b2);
System.out.println(!b2);
}
