Write a program whose input is two integers and whose output is the two integers swapped. Place the values in an array, where x

Aliun [14]

Answer:

import java.util.Arrays;

public class swap{

public static void main(String []args){

int [] arr = {2,4};

swapValues(arr);

}

public static void swapValues(int[] values){

int temp;

System.out.println(Arrays.toString(values));

temp=values[0];

values[0]=values[1];

values[1] =temp;

System.out.println(Arrays.toString(values));

}

Explanation:

In the program above, we created the method swapValues that receives an array of integers as parameters. in the method definition, we created a temp variable that is used to swapp the element at index 0 and index 1. Java's Arrays.to string method is used to print the array before and after the swap.

How to write a program that prompts the user to input two POSITIVE numbers — a dividend (numerator) and a divisor (denominator).

fomenos

Answer:

num1 = int(input("Numerator: "))

num2 = int(input("Denominator: "))

if num1 < 1 or num2<1:

print("Input must be greater than 1")

else:

print("Quotient: "+str(num1//num2))

print("Remainder: "+str(num1%num2))

Explanation

The next two lines prompts the user for two numbers

num1 = int(input("Numerator: "))

num2 = int(input("Denominator: "))

The following if statement checks if one or both of the inputs is not positive

if num1 < 1 or num2<1:

print("Input must be greater than 1")-> If yes, the print statement is executed

If otherwise, the quotient and remainder is printed

else:

print("Quotient: "+str(num1//num2))

print("Remainder: "+str(num1%num2))

Write an if statement that assigns 10,000 to the variable bonus if the value of the variable goodsSold is greater than 500,000.

aev [14]

Answer:

if(goodsSold>500000){

bonus = 10000;

}

Explanation:

A complete Java program that prompts user to enter value for goodsSold is given below:

import java.util.Scanner;

public class num14 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter goods Sold: ");

int goodsSold = in.nextInt();

int bonus =0;

if(goodsSold>500000){

bonus=10000;

}

System.out.println("You bonus for "+goodsSold+" is "+bonus);

}
