Java.lang.math.max()函数是Java中的内置函数，该函数最多返回两个数字。参数以int，double，float和long的形式接受，如果传递负数和正数作为参数，则生成正数结果。如果两个参数传递的都是负数，那么将生成幅度较小的数字。
用法:
dataType max(dataType num1, dataType num2)
The datatypes can be int, float, double or long.
参数： The function accepts two parameters num1 and num2
among which the maximum is returned
返回值：该函数最多返回两个数字。数据类型将与参数相同。
下面给出的是函数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
