Please help me solve this with java .... just the HangMan HangMan instruction class : • HangMan is a game in which a player tries to guess a word based on a given hint. For example, if the given hint is “movie”, then the player must guess a movie name. If the given hint is a “country”, then the player must guess a country name, and so on.• The game starts by showing a message on the screen that shows the hint and all letters in the word but obscured as dashes (-). Then, the game will allow the player to guess 5 letters. If the player gives a letter that actually exists in the word, then this letter will be revealed. Afterwards, the game will ask the player to give the answer. If the given answer is correct, then the game will show a message that the player has won 5 points. Otherwise, the game will show a message that the player has lost. Below is one possible game scenario, in which the word is “iron man”, and the hint is “movie”. Note that the text in green color is the…

4.34 LAB: Draw upside down triangle (JAVA) Write a program in java that outputs a right triangle of asterisks given the height as input. Each line ends with a blank space. Ex: If the input is: 3 the output is: * * * * * * Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); /* Type your code here. */ }}
4.31 LAB: Months until payoff (JAVA) Write a program in java that reads a loan amount, payment amount, and interest rate as inputs and outputs the number of payments required until the loan is paid. Interest is added to current balance before a payment is applied. Ex: If current balance is $100.00 and the interest rate is 0.02, the new balance is $102.00 before a payment is applied. All values are doubles. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); /* Type your code here. */ }}

Java - How do I output this statement as a horizontal statement with a newline? Everytime I use System.out.println, it makes the entire output vertical instead of horizontal. Program below. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { int x; int y; Scanner scan = new Scanner(System.in); x = scan.nextInt(); y = scan.nextInt(); if(y >= x){ for(int i=x; i<=y; i = i + 5) { System.out.print(i+ " "); (The problem line) } } else{ System.out.print("Second integer can't be less than the first."); } }}
