## How do you find the smallest number in Java?

1. public static void main(String[] args) {
2. System. out. println(“The largest number of the two numbers is ” + Math. max(num1,num2));
3. System. out. println(“The smallest number of the two numbers is ” + Math. min(num1,num2));

## How do you find the first digit of a number?

To finding first digit of a number is little expensive than last digit. To find first digit of a number we divide the given number by 10 until number is greater than 10. At the end we are left with the first digit.

## How do you find the maximum and minimum of an array?

Below is the step by step descriptive logic to find maximum or minimum in array. Input size and element in array, store it in some variable say size and arr . Declare two variables max and min to store maximum and minimum. Assume first array element as maximum and minimum both, say max = arr and min = arr .

## How do you find the largest and smallest number without using an array?

If you are sure that your input will only be a positive number then you can initialize the largest with zero instead of Integer. MIN_VALUE. The program is simple, just take input from the user about how many numbers and then uses a for loop to get that many numbers as input by using Scanner. nextInt() method.

## How do you find the greatest number in an array?

2. Run the for loop till the user-defined size to insert the element at each location. 3. Considering the first element of the array to be the largest, compare all the remaining elements of the array, and change the largest value if assumed largest element is smaller than the element being compared.

## How do you find the smallest number?

Steps to find the smallest number.

1. Count the frequency of each digit in the number.
2. Place the smallest digit (except 0) at the left most of required number. and decrement the frequency of that digit by 1.
3. Place all remaining digits in ascending order from left to right.

## What is the biggest number in Java?
