如何从Java扫描器中获取整数输入

Question

我在java中有这段代码，代码工作得很好

public class MaximumTest {
   // determines the largest of three Comparable objects
   public static <T extends Comparable<T>> T maximum(T x, T y, T z)
   {                      
      T max = x; // assume x is initially the largest       
      if ( y.compareTo( max ) > 0 ){
         max = y; // y is the largest so far
      }
      if ( z.compareTo( max ) > 0 ){
         max = z; // z is the largest now                 
      }
      return max; // returns the largest object   
   }
   public static void main( String args[] )
   {
      System.out.printf(maximum( 3, 4, 5 ) );
   }
}

import java.util.Scanner;
 public class MammalInt {

     public static <T extends Comparable<T>> T maximum (T x, T y, T z){
     T max=x;
     if(y.compareTo(max)>0){
    max= y;
     }
     if (z.compareTo(max)>0){
         max=z;
     } return max;
     }
    public static void main(String[] args) {

        Scanner x=new Scanner(System.in);
        Scanner y=new Scanner(System.in);
        Scanner z=new Scanner(System.in);

        System.out.println(maximum(x,y,z));

    }
    }

你对这个问题有什么解决办法吗？？？

谢谢

扫描器对象不是输入。扫描程序为您提供了一个方法NextInt()来请求用户输入。

您的主要方法应该是这样的：

public static void main(String[] args) {

    Scanner sc =new Scanner(System.in);
    int x = sc.nextInt();
    int y = sc.nextInt();
    int z = sc.nextInt();

    System.out.println(maximum(x,y,z));

}
