I have no idea what for loops are.. Can someone explain to me what for loops are and what they are used for? Also, can you give me other different types of loops?

So, could i use this for loop for my lives? I want it to show my lives, as my actor has three lives before it is game over? Where should i implement the code that you have given above in my game?
The code that you have gave me, i have used it but it didn't come up as incorrect but it also didn't do any changes to my game as well?
Show how and where you implemented it.
Since the number of lives can change as the player loses them, the code may need to be executed multiple times. Therefore, placing the code in a separate method would be the thing to do. Have it remove any icons previously placed before adding the new number of lives. In the world class, you could have this:
Then, in the world constructor, you would have:
to initially display the number of lives remaining. In the world act method, you could have something like the following:
public void adjustlives(int amount)
{
lives += amount;
removeObjects(getObjects(Life.class));
for (int i=0; i<lives; i++) addObject(new Life(), 50+i*30, 50);
}adjustLives(3);
if (player.getWorld() != this)
{
adjustLives(-1);
if (lives < 0) gameOver(); else resetLevel();
}OK, I have added the top part of the code within my level1 class, but at the moment nothing has occurred. I don't know what you mean by world constructor. I don't know where i should implement the rest of the code. At the moment, as you can see below, i have only done this:
public class level1 extends levels
{
int lives;
private static final int GAP = 30; // This will allow a specific gap between each 'Person'
private void createRows()
{
int y = 80; // This is the location the row will start from in the world from the y axis
while(y <= 700) // This is to adjust how many rows of people will there be in the world
{
createRows(y); // This is to create how many row of person you want depending on the y axis
y = y + 240 + GAP; // This is the calculation for the spaces between each Persons in the World
}
}
private void createRows(int y)
{
int x = 50; // This is the location the row will start from in the world from the x axis
while(x < 900) // if the ‘x’ are less than or equal to 900
{
addObject (new person(), x, y); // A new Person will be created at the coordinated that has been created at
x = x + 150 + GAP; // This is the calculation for the spaces between each row of people in the World
}
}
public void adjustlives(int amount)
{
lives += amount;
removeObjects(getObjects(HealthBar.class));
for (int i=0; i<lives; i++) addObject(new HealthBar(), 50+i*30, 50);
}Okay. First, let me correct a typo in what is now your line 25 above, which should be:
Now, your world constructor should begin like this:
You may or may not have some parameters between the parenthesis.
Curiously, I am not sure why you named the class that creates objects that represent lives 'HealthBar'.
public void adjustLives(int amount)
public level1()
