Answer 1

Explanation:

1. Answer :-

● Name your variables based on the terms of the subject area, so that the variable name clearly describes its purpose.

● Create variable names by deleting spaces that separate the words. ...

● Do not begin variable names with an underscore.

● Do not use variable names that consist of a single character.

2. Answer :-

Coercion means forcing a person to do something that they would not normally do by making threats against their safety or well-being, or that of their relatives or property. ... For example, pointing a gun at someone's head or holding a knife to someone's throat is an actual physical threat.

3. Answer :-

ceil() and Math. round() methods differ in a way that the former round off a number to its nearest integer in upward direction of rounding(towards the greater value) whereas the latter round off a number to its nearest integer in downward direction of rounding(towards lower value).

4. Answer :-

import java.util.Scanner;

public class Kboat3Numbers

{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

System.out.print("Enter first number: ");

int a = in.nextInt();

System.out.print("Enter second number: ");

int b = in.nextInt();

System.out.print("Enter third number: ");

int c = in.nextInt();

if (a == b && b == c) {

System.out.println("All the numbers are equal");

}

else {

int g = a;

if (b > g)

g = b;

if (c > g)

g = c;

System.out.println("Greatest number: " + g);

}

}

}
