Java Math max() 方法和示例

Java.lang.math.max()函数是Java中的一个内置函数,它最多返回两个数字。参数采用 int、double、float 和 long。如果将负数和正数作为参数传递,则生成正数结果。如果传递的两个参数都是负数,则生成具有较低幅度的数字作为结果。

句法:

dataType max(dataType num1, dataType num2)
The datatypes can be int, float, double or long.

Parameters : The function accepts two parameters num1 and num2 
among which the maximum is returned

返回值:函数返回最多两个数字。数据类型将与参数的数据类型相同。

下面给出了函数max() 的示例

// Java program to demonstrate the use of max() function
// when two double data-type numbers are
// passed as arguments
public class Gfg {
  
    public static void main(String args[])
    {
        double a = 12.123;
        double b = 12.456;
  
        // prints the maximum of two numbers
        System.out.println(Math.max(a, b));
    }
}

输出:

12.456
// Java program to demonstrate the use of max() function
// when one positive and one negative
// integers are passed as argument
public class Gfg {
  
    public static void main(String args[])
    {
        int a = 23;
        int b = -23;
  
        // prints the maximum of two numbers
        System.out.println(Math.max(a, b));
    }
}

输出:

23
// Java program to demonstrate the use of max() function
// when two negative integers are passed as argument.
public class Gfg {
  
    public static void main(String args[])
    {
        int a = -25;
        int b = -23;
  
        // prints the maximum of two numbers
        System.out.println(Math.max(a, b));
    }
}

输出:

-23
