Java Math Mathematical Methods
The Java Math min() method returns the smallest value among the specified parameters.
The syntax of the min() method is:
Math.min(arg1, arg2)
Note：min() is a static method. Therefore, we can access this method using the Math class name.
arg1 / arg2 - Parameter for returning the minimum value
NoteNote: The data types of each parameter should be int, long, float, or double.
Returns the minimum value among the specified parameters
class Main {
public static void main(String[] args) {
//Math.min() with int parameter
int num1 = 35;
int num2 = 88;
System.out.println(Math.min(num1, num2}); // 35
/with long parameter/Math.min()
long num3 = 64532L;
long num4 = 252324L;
System.out.println(Math.min(num3, num4}); // 64532
//Math.min() with float parameter
float num5 = 4.5f;
float num6 = 9.67f;
System.out.println(Math.min(num5, num6}); // 4.5
//Math.min() with double parameter
double num7 = 23.44d;
double num8 = 32.11d;
System.out.println(Math.min(num7, num8}); // 23.44
}
}In the above example, we use the Math.min() method with int, long, Float, and Double type parameters.
class Main {
public static void main(String[] args) {
//Create an int array
int[] arr = {4, 2, 5, 3, 6};
//Assign the first element of the array as the minimum value
int min = arr[0];
for (int i = 1; i < arr.length; i++) {
//Compare all elements with min
//Assign the minimum value to min
min = Math.min(min, arr[i]);
}
System.out.println("Minimum value: " + min);
}
}In the above example, we created an array named arr.Array. Initially, the variable min stores the first element of the array.
Here, we use a for loop to access all elements of the array. Note this line,
min = Math.min(min, arr[i])
The Math.min() method compares the variable min with all elements of the array and assigns the minimum value to min.
