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
