Thread: Very basic coding question, I'd appreciate feedback.

Hi guys, I'm brand-new to Java, self-teaching. If one of the wizards could tell me what I'm doing wrong here, or ideally give me a better way to solve this problem, I'd be eternally appreciative.
The challenge is incredibly simple, but I only want to use functions, classes or objects that I've referenced in the code below - there's not point me using more advanced functions when I haven't learnt them yet.
The idea is to ask for 3 names from the user, sort them and return them in alphabetical order to the user. I want to use the scanner class for input.
My issue is that my code below has compilation errors which I don't understand.

//Sorted names
//Ask the user to enter three names
//Return the names in alphabetic order
 
import javax.swing.JOptionPane;
import java.util.Scanner;
 
public class Challenge007Prompt
{
	public static void main(String args[])
	{
		String name1, name2, name3;
		char name1Char, name2Char, name3Char;
		char name1CharStr, name2CharStr, name3CharStr;
		String firstChar, secondChar, thirdChar;
 
		Scanner keyboard = new Scanner(System.in);
 
		System.out.println("Please enter the first name");
		name1 = keyboard.nextLine();
		System.out.println("First name is: " + name1);
 
		System.out.println("Please enter the second name");
		name2 = keyboard.nextLine();
		System.out.println("Second name is: " + name2);
 
		System.out.println("Please enter the third name");
		name3 = keyboard.nextLine();
		System.out.println("Third name is: " + name3);
 
		name1Char = name1.charAt(0);
		name2Char = name2.charAt(0);
		name3Char = name3.charAt(0);
 
 
		if(name1Char < name2Char && name1Char < name3Char)
			firstChar=name1;
		else
			if(name2Char < name1Char && name2Char < name3Char)
				firstChar=name2;
		else
			if(name3Char < name1Char && name3Char < name2Char)
				firstChar=name3;
 
		if(name1Char > name2Char && name1Char > name3Char)
			thirdChar=name1;
		else
			if(name2Char > name1Char && name2Char > name3Char)
				thirdChar=name2;
		else
			if(name3Char > name1Char && name3Char > name2Char)
				thirdChar=name3;
 
		name1CharStr = firstChar.charAt(0);
		name2CharStr = secondChar.charAt(0);
		name3CharStr = thirdChar.charAt(0);
 
		if(name1Char==name1CharStr || name1Char==name3CharStr)
			secondChar=name1;
		else
			if(name2Char==name1CharStr || name1Char==name3CharStr)
			secondChar=name2;
		else
			secondChar=name3;
 
		System.out.println(firstChar + secondChar + thirdChar);
 
		System.exit(0);
	}
}

What are the compilation errors? Also, please use the highlight tags when posting code.

You might also want to look at the compareTo() function of the String class.
