**java.lang.Math **class comes with many methods to do simple basic numeric operations. One such one is **min()** method which returns the minimum of two numbers passed as parameter.

One advantage of** Math** class methods is that they are declared as **static** so that they can be called without the need of object creation.

Following is the **Math** class signature as defined in **java.lang** package.

**public final class Math extends Object**

**min()** method in **Math **class is 4 times overloaded accepting 4 different types of arguments.

**int min(int a, int b):**Returns minimum of two integer values passed as parameter.**long min(long a, long b):**Returns minimum of two long values passed as parameter.**float min(float a, float b):**Returns minimum of two float values passed as parameter.**double min(double a, double b):**Returns minimum of two double values passed as parameter.

Observe, the above methods data type of the returned value is the same as parameters.

###### Following example on "Find Minimum of Two Numbers min() Java "illustrates of the above four methods.

```
public class MathFunctionDemo
{
public static void main(String args[])
{
int a = 25, b = 50; // two integer values
long c = 50, d = 20; // two long values
float e = 25.5f, f = 10.4f; // two float values
double g = 20.3, h = 50.2; // two double values
System.out.println("Minimum of integer values 25 and 50 is " + Math.min(a, b));
System.out.println("Minimum of long values 50 and 20 is " + Math.min(c, d));
System.out.println("Minimum of float values 25.5 and 10.4 is " + Math.min(e, f));
System.out.println("Minimum of double values 20.3 and 50.2 is " + Math.min(g, h));
}
}
```
