## How do you find the maximum of 5 numbers in Java?

**Find Largest Number in Array using Arrays**

- import java.util.Arrays;
- public class LargestInArrayExample1{
- public static int getLargest(int[] a, int total){
- Arrays.sort(a);
- return a[total-1];
- }
- public static void main(String args[]){
- int a[]={1,2,5,6,3,2};

## How do you find the maximum of a number in Java?

**To find the maximum value in an array:**

- Assign the first (or any) array element to the variable that will hold the maximum value.
- Loop through the remaining array elements, starting at the second element (subscript 1). When a larger value is found, that becomes the new maximum.

## How do you find the minimum of 5 numbers in Java?

**Let’s see another example to get the smallest element or number in java array using Arrays.**

- import java.util.*;
- public class SmallestInArrayExample1{
- public static int getSmallest(int[] a, int total){
- Arrays.sort(a);
- return a[0];
- }
- public static void main(String args[]){
- int a[]={1,2,5,6,3,2};

## How do you find min and max in java?

**Using Arrays.** **sort method to Find Maximum and Minimum Values in an Array**

- int[] nums={6,-1,-2,-3,0,1,2,3,4};
- Arrays. sort(nums);
- System. out. println(“Minimum = ” + nums[0]);
- System. out. println(“Maximum = ” + nums[nums. length-1]);

## How do you find the smallest digit in a number?

Take a number n as the input. An integer **function smallest_digit(int n)** takes ‘n’ as the input and returns the smallest digit in the given number. Now initialize min as the last digit of the given number. Iterate through the number and check if the number extracted is less than the minimum number.

## How do you find the greatest of 4 numbers?

**Algorithm**

- START.
- INPUT FOUR NUMBERS A, B, C, D.
- IF A > B THEN. IF A > C THEN. IF A > D THEN. A IS THE GREATEST. ELSE. D IS THE GREATEST.
- ELSE IF B > C THEN. IF B > D THEN. B IS THE GREATEST. ELSE. D IS THE GREATEST.
- ELSE IF C > D THEN. C IS THE GREATEST.
- ELSE. D IS THE GREATEST.

## What is Max in Java?

max() function is an inbuilt function in Java which **returns maximum of two numbers**. The arguments are taken in int, double, float and long. If a negative and a positive number is passed as argument then the positive result is generated.

## How do you find the minimum value in an ArrayList?

For finding minimum and maximum values from the ArrayList, we simply need **to find the first and last element of the ArrayList**, because the ArrayList is sorted in ascending order then the first element will be the smallest and the last element will be largest among all of the elements.

## What is math floor in Java?

Math. floor() **returns the double value that is less than or equal to the argument and is equal to the nearest mathematical integer**. Note: If the argument is Integer, then the result is Integer. If the argument is NaN or an infinity or positive zero or negative zero, then the result is the same as the argument.

## How do you find the minimum of two numbers in Java?

**min() function** is an inbuilt function in java that returns the minimum of two numbers. The arguments are taken in int, double, float and long. If a negative and a positive number is passed as an argument then the negative result is generated.

## How do you find the minimum in Java?

The **Java.** **lang.** **math.** **min()** is an inbuilt method in Java which is used to return Minimum or Lowest value from the given two arguments.

…**Example 1:**

- public class MinExample1.
- {
- public static void main(String args[])
- {
- int x = 20;
- int y = 50;
- //print the minimum of two numbers.
- System. out. println(Math. min(x, y));

## How do you check if an ArrayList is empty?

To check if an ArrayList is empty, you can use **ArrayList.** **isEmpty() method** or first check if the ArrayList is null, and if not null, check its size using ArrayList. size() method. The size of an empty ArrayList is zero.

## How do you find the minimum and maximum of numbers?

**HOW TO FIND MAXIMUM AND MINIMUM VALUE OF A FUNCTION**

- Differentiate the given function.
- let f'(x) = 0 and find critical numbers.
- Then find the second derivative f”(x).
- Apply those critical numbers in the second derivative.
- The function f (x) is maximum when f”(x) < 0.
- The function f (x) is minimum when f”(x) > 0.
