The max() method returns the maximum value among the specified arguments.
Example
class Main {
public static void main(String[] args) {
// compute max of 88 and 98
System.out.println(Math.max(88, 98));
}
}
// Output: 98
Syntax of Math.max()
The syntax of the max() method is:
Math.max(arg1, arg2)
Here, max() is a static method. Hence, we are accessing the method using the class name, Math.
max() Parameters
The max() method takes two parameters.
- arg1/arg2 - arguments among which maximum value is returned
Note: The data types of the arguments should be either int, long, float, or double.
max() Return Value
- returns the maximum value among the specified arguments
Example 1: Java Math.max()
class Main {
public static void main(String[] args) {
// Math.max() with int arguments
int num1 = 35;
int num2 = 88;
System.out.println(Math.max(num1, num2)); // 88
// Math.max() with long arguments
long num3 = 64532L;
long num4 = 252324L;
System.out.println(Math.max(num3, num4)); // 252324
// Math.max() with float arguments
float num5 = 4.5f;
float num6 = 9.67f;
System.out.println(Math.max(num5, num6)); // 9.67
// Math.max() with double arguments
double num7 = 23.44d;
double num8 = 32.11d;
System.out.println(Math.max(num7, num8)); // 32.11
}
}
In the above example, we have used the Math.max() method with int, long, float, and double type arguments.
Example 2: Get a maximum value from an array
class Main {
public static void main(String[] args) {
// create an array of int type
int[] arr = {4, 2, 5, 3, 6};
// assign first element of array as maximum value
int max = arr[0];
for (int i = 1; i < arr.length; i++) {
// compare all elements with max
// assign maximum value to max
max = Math.max(max, arr[i]);
}
System.out.println("Maximum Value: " + max);
}
}
In the above example, we have created an array named arr. Initially, the variable max stores the first element of the array.
Here, we have used the for loop to access all elements of the array. Notice the 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.
