Java program to Implement Mathematical functions defined in Java Math class

• Max(parameters) Method- Return the maximum value
  • Static int max(int x, int y)
  • Static long max(int x, int y)
  • Static double max(int x, int y)
  • Static float max(int x, int y)
• Min(parameters) method- Return the minimum value
  • Static int min(int x, int y)
  • Static int min(int x, int y)
  • Static int min(int x, int y)
  • Static int min(int x, int y)

Java Program:
import java.lang.*;
import java.util.*;

public class minmax
{
  public static void main(String args[])
  {
  int x=10,y=20;
  int x=Math.min(x,y);
  System.out.println("Minimum value between 10 & 20 is "+z);
  int x=Math.max(x,y);
  System.out.println("Maxmimum value between 10 & 20 is "+z);
  }
}

output:
 Minimum value between 10 & 20 is 10
 Maximum value between 10 & 20 is 20

Absolute Method Defined by Java Math class

• abs(parameter):- Return the absolute value of argument
  • static int abs(int arg)
  • static long abs(long arg)
  • static float abs(float arg)
  • static double abs(double arg)

Java program to use absolute method:
import java.util.*;
import java.lang.*;
public class absolute
{
 public static void main(String args[])
 {
  double a=1.500;
  double z=Math.abs(a);
  System.out.println("Absolute of 1.500 is")
 }
}
output:
Absolute of 1.500 is 1.5

Round off method defined in Java Math class

• round(parameter):- return arguments rounded value.
  • static int round(float args)
  • static int round( double args)

import java.util.*;
import java.lang.*;
class Round
{
 public static void main(String args[])
 double a=1.50,b=1.49;
 double z=Math.round(a);
 System.out.println("Round value of 1.50= "+z);
 double x=Math.round(a);
 System.out.println("Round value of 1.49= "+x);
}
}

Output:
Round value of 1.50= 2.0
Round value of 1.49= 1.0

Other Methods Defined in Java Math class

• sqrt()- Used to return the Square root of the number.
  • Syntax :- static double sqrt(double arg)
• pow()- Used to return power of given number.
  • Syntax :- static double pow(double y, double x)

Java program:
import java.lang.*;
import java.util.*;
public class example
{
 public static void main(String args[])
{
 int a=16,b=2;
 double z=Math.sqrt(a);// to find square root
 System.out.println("Square of Number is:-" +z);
 double x=Math.pow(a,b);
 System.out.println("Power of given Number:-");
}
}

Output:
Square root of Number is:- 4
Power of given Number:-256
