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 maximum and minimum of an array?

Logic to find maximum and minimum element in array Assume first array element as maximum and minimum both, say max = arr[0] and min = arr[0]. Iterate through array to find maximum and minimum element in array. Run loop from first to last array element i.e. 0 to size – 1.

  1. import java.util.*;
  2. public class SecondSmallestInArrayExample1{
  3. public static int getSecondSmallest(int[] a, int total){
  4. Arrays.sort(a);
  5. return a[1];
  6. }
  7. public static void main(String args[]){
  8. int a[]={1,2,5,6,3,2};

How do you find the smallest number with 3 numbers?

Program Explanation Get three inputs num1, num2 and num3 from user using scanf statements. Check whether num1 is smaller than num2 and num3 using if statement, if it is true print num1 is smallest using printf statement. Else, num2 or num3 is smallest. So check whether num2 is smaller than num3 using elseif statement.

  4. {
  5. int x = 20;
  6. int y = 50;
  7. //print the minimum of two numbers.
  8. System. out. println(Math. min (x, y));
