Answer:

myString=myString.toUpperCase();

Explanation:

In java to change all characters of a string to upper case we use .toUpperCase() method.It will convert string to upper case.

Implementation in java.

import java.util.*;

class Solution

{

public static void main (String[] args) throws java.lang.Exception

{

try{

Scanner scr=new Scanner(System.in);

System.out.print("Enter a string:");

String myString=scr.nextLine();

myString=myString.toUpperCase();

System.out.println("string in upper case : "+myString);

}catch(Exception ex){

return;}

}

Output:

Enter a string:hello

string in upper case : HELLO

Create and test a user-defined function named ufnFullName that combines the values of the two parameters named FirstName and Las

8090 [49]

Answer:

public static String ufnFullName(String Fname, String Lname){

String FullName = Fname+" "+Lname;

return FullName;

}

Explanation:

Using Java programming language, the function is created to accept two String parameters (Fname and Lname)

These are concatenated into a new String FullName and returned by the function

See below a complete code that prompts users to enter value for first and last names then calls this method to display the full name

import java.util.Scanner;

public class FullName {

public static void main(String[] args) {

System.out.println("Enter First Name");

Scanner in = new Scanner(System.in);

String Fname = in.next();

System.out.println("Enter Last Name");

String Lname = in.next();

System.out.println("Your Full Name is "+ufnFullName(Fname,Lname));

}

public static String ufnFullName(String Fname, String Lname){

String FullName = Fname+" "+Lname;

return FullName;

}

}

The following checksum formula is widely used by banks and credit card companies to validate legal account numbers: d0 + f(d1) +

Aleksandr [31]

Answer:

Here is the JAVA program:

import java.util.Scanner; //to import Scanner class

public class ISBN

{ public static void main(String[] args) { // start of main() function body

Scanner s = new Scanner(System.in); // creates Scanner object

//prompts the user to enter 10 digit integer

System.out.println("Enter the digits of an ISBN as integer: ");

String number = s.next(); // reads the number from the user

int sum = 0; // stores the sum of the digits

for (int i = 2; i <= number.length(); i++) {

//loop starts and continues till the end of the number is reached by i

sum += (i * number.charAt(i - 1) ); }

/*this statement multiplies each digit of the number with i and adds the value of sum to the product result and stores in the sum variable*/

int remainder = (sum % 11); // take mod of sum by 11 to get checksum

if (remainder == 10)

/*if remainder is equal to 10 adds X at the end of given isbn number as checksum value */

{ System.out.println("The ISBN number is " + number + "X"); }

else

// displays input number with the checksum value computed

{System.out.println("The ISBN number is " + number + remainder); } } }

Explanation:

This program takes a 10-digit integer as a command line argument and uses Scanner class to accept input from the user.

The for loop has a variable i that starts from 2 and the loop terminates when the value of i exceeds 10 and this loop multiplies each digit of the input number with the i and this product is added and stored in variable sum. charAt() function is used to return a char value at i-1.

This is done in the following way: suppose d represents each digit:

sum=d1 * 1 + d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5 + d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9

Next the mod operator is used to get the remainder by dividing the value of sum with 11 in order to find the checksum and stores the result in remainder variable.

If the value of remainder is equal to 10 then use X for 10 and the output will be the 10 digits and the 11th digit checksum (last digit) is X.

If the value of remainder is not equal to 10, then it prints a valid 11-digit number with the given integer as its first 10 digits and the checksum computed by sum % 11 as the last digit.
