Proper if Statements: Help

[socboy6579]

Would i need to use else if statements for this

public static String GarageHolds(ArrayList<Garage> myCars)
	{
		if (myCars.size() < 25);
		return "below minimum";
		
		else if(myCars.size() >= 25 && myCars.size() <100);
		return "normal load";
		
		else if(myCars.size() >= 100);
		return "full";
	}

When i try just to use regualr if statements the last 2 statements become "unreachable". Could this be solved by using if else?

		if (myCars.size() < 25);

Remove the trailing semicolon(s) (also on the other lines with if-clauses).

kind regards,

Jos

thank you i figured it out.

public static String GarageHolds(ArrayList<Garage> myCars)
	{
		if (myCars.size() < 25){
		return "below minimum";
		
		} else if(myCars.size() >= 25 && myCars.size() <100){
		return "normal load";
		
		} else if(myCars.size() >= 100);
		return "full";
	}

Thank you. and one more question if you wuld be able to answer this

import java.util.ArrayList;
public class Garage {

	private static int milesDriven;
	private static int GallonsGas;
	
	public Garage(int MilesDrove, int AmtGallonsGas)
	{
		this.milesDriven=milesDriven;
		this.GallonsGas=GallonsGas;
	}
	
	public int getMilesDrove()
	{
		int returnMilesDrove= milesDriven;
		return returnMilesDrove;
	}
	
	public int getAmtGallonsGas()
	{
		int returnAmtGallonsGas= GallonsGas;
		return returnAmtGallonsGas;
	}
	
	public static void main(String[] args)
	{
		Garage auto1 = new Garage(5000, 2679);
		Garage auto2 = new Garage(4325, 1931);
		Garage auto3 = new Garage(2452, 978);
		Garage auto4 = new Garage(6742, 2979);
		Garage auto5 = new Garage(10000, 4503);
		
		ArrayList<Garage> myCars =  new ArrayList<Garage>();
		myCars.add(auto1);
		myCars.add(auto2);
		myCars.add(auto3);
		myCars.add(auto4);
		myCars.add(auto5);
		
		System.out.println(myCars.size());
	}
	
	public static int averageMiles(ArrayList<Garage> myCars)
	{
		int sum= 0;
		for(int i=0; i < myCars.size(); i++)
			sum+= myCars.get(i).getMilesDrove();
		return sum/myCars.size();
	}
	
	public static String GarageHolds(ArrayList<Garage> myCars)
	{
		if (myCars.size() < 25){
		return "below minimum";
		
		} else if(myCars.size() >= 25 && myCars.size() <100){
		return "normal load";
		
		} else if(myCars.size() >= 100);
		return "full";
	}
	
	public static int numGallons(ArrayList<Garage> myCars)
	{
		int sum=0;
		for(int i=0; i < myCars.size(); i++)
			sum+= myCars.get(i).getAmtGallonsGas();
		return sum;
	}
}

How would i call the averageMiles, GarageHolds, and the numGallons methods in the main method..

System.out.println(averageMiles(myCars))?
