using java other than 1,2,3,4,5 inputs will be discarded Volts [4] is an array that will only save voltages that are in the range of 1V-5V. Your program will continue to ask for a voltage input and save it in the array given that is in the range and if until the array is full. Display the voltage values in the array

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…
IN JAVA - Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. End with a newline. Ex: If the input is: -15 10 the output is: -15 -10 -5 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last. BASE CODE: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { /* Type your code here. */ }}
In Java please. Reimplement the TrafficLight class using a simple counter that is advanced in each call to next. If the traffic light was initially green, the counter has values 0 1 2 3 4 5 6 … .

This is java. Please help me. And please add comments in the code
A simple plant -see the figure- can be constructed using simple Java instructions.a. Write a java code to construct the above shape.b. A list of such plant on the same line can be easily constructed using suitable Java geometric transformations -see the figure- develop a java code to make such line of plants. c. Many successive lines can also be constructed to create a field of plants, develop a java code to implement the plants field. d. Using suitable rendering, you can assign different random colors -of course all of the colors are of green grades- to each plant, develop a java code to implement such coloring. e. Using suitable randomization, rotate each plant in d) to mimic the situation that some plants are not totally vertical. f. Using suitable randomization, write a java code to assign a different size to each plant. g. If we want to change the direction of the full scene in f) with an arbitrary angle, write a java code to do that. h. Snapshot the output in g)java Code
