1、输入的a是整数：
package test;
import java.util.Scanner;

public class aaaa {
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
System.out.println("请输入a：");
int a = s.nextInt();
double b = 0.0;
b = result(a,b);
System.out.println("结果b="+b);
}
private static double result(int a,double b) {
b = Math.round(15/(32*a))+21;
return b;
}

}

2、输入的a是小数或整数
package test;
import java.util.Scanner;

public class aaaa {
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
System.out.println("请输入a：");
double a = s.nextDouble();
double b = 0.0;
b = result(a,b);
System.out.println("结果b="+b);
}
private static double result(double a,double b) {
b = Math.round(15/(32*a))+21;
return b;
}

}
