Write a function that takes in the radius as input and returns the circumference of a circle.
import java.util.*;
public class Solutions {
public static Double getCircumference(Double radius) {
return 2 * 3.14 * radius;
}
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
Double r = sc.nextDouble();
System.out.println(getCircumference(radius));
}
}
Find the maximum & minimum number in an array of integers.
[HINT : Read about Integer.MIN_VALUE & Integer.MAX_VALUE in Java]
Take an array of numbers as input and check if it is an array sorted in ascending order.
Eg : { 1, 2, 4, 7 } is sorted in ascending order.
{3, 4, 6, 2} is not sorted in ascending order.
Write a program to enter the numbers till the user wants and at the end it should display the count of positive, negative and zeros entered.
