Java Math min() 方法和示例
Java.lang.math.min()函数是Java中的一个内置函数,它返回两个数字中的最小值。参数采用 int、double、float 和 long。如果将负数和正数作为参数传递,则生成负数结果。如果传递的两个参数都是负数,则生成具有较高幅度的数字作为结果。
句法:
dataType min(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 minimum is returned
返回值:函数返回两个数字中的最小值。数据类型将与参数的数据类型相同。
下面给出了函数min() 的示例:
Java
// Java program to demonstrate the
// use of min() function
// two double data-type numbers are passed as argument
public class Gfg {
public static void main(String args[])
{
double a = 12.123;
double b = 12.456;
// prints the minimum of two numbers
System.out.println(Math.min(a, b));
}
}
Java
// Java program to demonstrate the
// use of min() 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 minimum of two numbers
System.out.println(Math.min(a, b));
}
}
Java
// Java program to demonstrate
// the use of min() 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 minimum of two numbers
System.out.println(Math.min(a, b));
}
}
Java
import static java.lang.Math.min;
class GFG {
public static void main(String[] args)
{
int a = 3;
int b = 4;
System.out.println(min(a, b));
}
}
输出:
12.123

public class Gfg {
public static void main(String args[])
{
int a = 23;
int b = -23;
// prints the minimum of two numbers
System.out.println(Math.min(a, b));
}
}
输出:
-23
Java
// Java program to demonstrate
// the use of min() 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 minimum of two numbers
System.out.println(Math.min(a, b));
}
}
输出:
-25
如果您想在代码中多次找到两个数字的最小值,那么每次编写完整的Math.min()往往很乏味。因此,一个更短且更省时的方法是直接将Java.lang.Math.min作为静态导入,然后只使用min()而不是完整的Math.min() 。
Java
import static java.lang.Math.min;
class GFG {
public static void main(String[] args)
{
int a = 3;
int b = 4;
System.out.println(min(a, b));
}
}
输出
