Question

USE JAVA. Just a basic code. We these in Blue J

2) Write a while loop that lets the user enter a number. The number should be multiplied by 10 and the result stored in the variable product. The loop should iterate as long as product contains a value less than 100. 3) Write a do-while loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The user should be asked if he or she wishes to perform the operation again. If so, the loop should repeat. Otherwise, it should terminate.

Quesiton 2:

Here is code:

import java.util.Scanner;

Scanner cin = new Scanner(System.in);

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

int product = cin.nextInt();

while (product < 100) {

product = product * 10;

}

System.out.println("Product value is : " + product);

}

}

Output:

Here is code:

import java.util.Scanner;

public class Sum {

public static void main(String[] args) {

Scanner cin = new Scanner(System.in);

int choice;

do {

System.out.print("Enter number #1 : ");

int num1 = cin.nextInt();

System.out.print("Enter number #2 : ");

int num2 = cin.nextInt();

System.out.println("The sum of numbers are : " + (num1 + num2));

System.out.print("Do you like to continue (1/0) : ");

choice = cin.nextInt();

} while (choice == 1);

}

}

Output:
