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