Java中从键盘输入多个整数的方法

import java.util.scanner;

import java.lang.math.*;

class test1{

     public static void main(string [] args){

      scanner sc= new scanner(system.in);

      int m;

      double n,result;

      while (sc.hasnextint()){

         n=sc.nextint();

         m=sc.nextint();

         result= 0 ;

         for ( int i= 0 ; i<m; i++){

             result += n;

             n = math.sqrt(n);

           }

       system.out.printf( "%.2f" ,result);

      }

     }

}

class test{

     public static void main(){

         scanner sc= new scanner(system.in);

         string input=sc.nextline();

         input=input.trim(); //去掉字符串首尾空格

         string[] temp=input.split( " " ); //按照指定字符串分割某个字符串并以字符串数组形式返回

         double n=integer.parsedouble(temp[ 0 ]);

         int m=integer.parseint(temp[ 1 ]);

         double result= 0 ;

         for ( int i= 0 ; i<m; i++){

             result += n;

             n = math.sqrt(n);

         }

         system.out.println(result);

     }
