Modify the command-line argument example Hello.java, to handle a few command-line arguments. Ask the user to enter a name followed by a number. The program should print out the name N times, while N is the input number.
For example, if the command-line input is
Java Hello Jim R. Joseph 5
Then the output should be:
Jim R. Joseph
Jim R. Joseph
Jim R. Joseph
Jim R. Joseph
Jim R. Joseph
Now what I got was this which is incorrect
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner (System.in);
System.out.print("Enter the name: ");
String name = input.nextLine();
System.out.print("Enter the value of n: ");
int num = input.nextInt();
int j = 0;
while(j < num){
System.out.println(name);
j++;
}
}
}
But the correct way to do it is to use the command-line arguments to send in the name and number, instead of the Scanner. So you can retrieve the name from args[0] and number from args[3].

- In Java: Many documents use a specific format for a person's name. Write a program whose input is: firstName middleName lastName, and whose output is: lastName, firstName middleInitial. Ex: If the input is: Pat Silly Doe the output is: Doe, Pat S. If the input has the form firstName lastName, the output is lastName, firstName. Ex: If the input is: Julia Clark the output is: Clark, Julia import java.util.Scanner; public class LabProgram {public static void main(String[] args) {JAVA Write a program that allows a user to enter a series of numbers and displays frequency of each number. Implement the following: 1. The user can enter a maximum of 20 numbers or enter-1 to end the series (i.e. they can enter less than 20 numbers by entering -1) 2. Only numbers between 0-9 is allowed (or -1 ); if the user enters a number outside the valid input, inform the user and ask them to enter a valid number; keep repeating till a valid input is entered. Implement reading and validation of user input in a class "UserInput" - it should have a static method getNextNumber() that returns a valid integer. In your main program, use UserInput.getNextNumber() to read a valid input. 3. Display the frequency of each number in the output, in the following format Number: Frequency For example, if the user input is 0,0,1,2,2,4,5,8,8,8,9,9, -1 the output will be: 0: 2 1; 1 2: 2 3: 0 4: 1 5: 1 6: 0 7: 0 8: 3 9: 2Exercise 1 : Write a Java program that computes the sum of even numbers less than or equal to n where n is given by the user (without nesting the control statements). Exercise 2 : Write a Java application that computes the sum of even numbers and the product of odd numbers that are in the range [a, b] where a and b are given by the user (without nesting the control statements, to do so you have to use 2 separate loops).
- Please write a program which prints out the following story. The user gives a name and a year, which should be inserted into the printout. Please type in a name: Mary Please type in a year: 1572 Mary is a valiant knight, born in the year 1572. One morning Mary woke up to an awful racket: a dragon was approaching the village. Only Mary could save the village's residents. The story should change according to the input given by the user. Sample output 1In java Develop a function that takes two integers and returns the sum of the values from the first to the second (the two inputs may be in any order). Call the function at least twice with different arguments Develop a void function PrintLineOfChar that accepts a single character and an integer. The function prints a single line of the character repeated the integer number of times. Call the function at least twice with different arguments.Python Write a program that asks the user for two integers that will correspond to the numbering of the first and last lines, then a third integer that will correspond to the number of z before "zigzag" (not counting the first "z" of zigzag), then finally that displays a zig-zag following the following pattern: Exemple 1: Start Number: * user type 3 * End number: * user type 10 * Number of z: * user type 5 * zzzzzzigzag 3 4 zzzzzzigzag zzzzzzigzag 5 6 zzzzzzigzag zzzzzzigzag 7 8 zzzzzzigzag zzzzzzigzag 9 10 zzzzzzigzag (Even integers must be left-zigzag and odd integers must be right.) Example 2: Start number:* user type -2 * End Number:* user type 4 * Number of z: * user type 3 * -2 zzzzigzag zzzzigzag -1 0 zzzzigzag zzzzigzag 1 2 zzzzigzag zzzzigzag 3 4 zzzzigzag Example 3: Start Number:* user type 5 * End number:* user type 0 * Number of z: * user type 10 * (Nothing is displayed because 5>0)
- Homework 1. Write a program to have the user guess a number stored in the program. If he guesses right, tell him so. If he guesses wrong also tell him. 2. Write a program with a user interface which allows the user to enter 2 integers. It should then give him the option of adding them, subtracting them, multiplying them or dividing them. It should then print the result. 3. Write a program with a user interface to allow a user to enter a number and to tell him whether the number is even or odd. Use the truncating property of int to do this. 4. Write a program with a user interface which allows the user to enter two numbers. Check if the first number is a multiple of the second number. If it is tell the user; if it isn't tell him also. 5. Write a program in which the user inputs a letter and you print it back If the letter is already t it cap again for him. 6. Same a previous question, only this time if it is capital, print it lowercase. 7. Let the user enter 3 numbers. Print the numbers…in Java, Write a program that reads student scores, gets the best score, and then assigns grades based on the following scheme:• Grade is A if score is ≥ best − 10• Grade is B if score is ≥ best − 20;• Grade is C if score is ≥ best − 30;• Grade is D if score is ≥ best − 40;• Grade is F otherwise.The program prompts the user to enter the total number of students, then prompts the user to enter all of the scores, and concludes by displaying the grades. Here is a sample run: number of students: 4 scores are: 40.0, 55.0, 70.0, 58.0 Student 0 score is 40.0 and grade is C Student 1 score is 55.0 and grade is B Student 2 score is 70.0 and grade is A Student 3 score is 58.0 and grade is BWrite a program using java language that will do the following: 1.

Write a code that will randomly fill in the rooms between the range given in number 2. 4. Print the contents of the rooms 5. Find the room number of any number that is entered by the user Search the contents of the rooms 6. If the number entered is found, print its room number If the number entered is not in the room, print that it is not found

The program should ask theuser to enter three test scores and then assign the values entered to the variables. The programshould display the average of the test scores and the letter grade that is assigned forthe test score average. Use the grading scheme in the following table:For this assignment, write a program called Payday.java that will compute and print a person's paycheck. The program will ask the user for the number of hours they worked and their hourly payrate. It will ask the person if they are a union member, in which case 5% of the salary will be withheld for union dues. It will ask the person if the percentage they wish to set aside for their medical savings account. It will then apply a sliding tax scale, defined as follows: Greater than or equal to $2,500 $1,500 up to $2,500 $500 up to $1,500 Less than $500 25% 15% 10% 5% The program must then print a formatted paycheck that shows their gross pay, union deduction, medical deduction, taxes withheld, and net pay. Use a function to determine the tax rate. Use a different function to print the nicely formatted paycheck. Your program should operate like this: ********** ********** Payday V1.0 ***: ******** Enter name: Ray Klump Enter hours worked: 43.25 Enter hourly pay rate: 17.50 Are you a union…
