java - 求 int 和 double 的最大值？

Question

如何获取给定 int 和 double 值的最大值？

package _pasted_code_;
import java.util.Scanner;

public class extra {

    public static void main(String[] args) {
        double x = 2.0;
        double y = 3.0;
        double z = 5.67;
        int a = 3;
        int b = 9;
        double answer = max(x, y);
        System.out.println("The largest number is: " + answer);
        double answer = max(x, y, z);
        int max = max(a, b);
    }   

  public static double max(double num1, double num2) { 
    if (num1 > num2)
      return num1;
    else
      return num2;
  }

  public static int max (int x, int y) {

      if (x > y)
          return x;
        else
          return y;
  }

  public static double max(double num1, double num2, double num3) {
    if ((num1 > num2) && (num1 > num3))
      return num1;
    else
      return num2;
    else  
      return num3;
  }
}

Answer 1

您可以使用Math.max(double a, double b) 和 Math.max(int a, int b)

示例:

public static int max(int x, int y) {
    return Math.max(x, y);
}
public static double max(double num1, double num2) { 
    return Math.max(num1, num2);
}
public static double max(double num1, double num2, double num3) {
    return Math.max(Math.max(num1, num2), num3);
}
