    Default 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)
    			if(name2Char < name1Char && name2Char < name3Char)
    			if(name3Char < name1Char && name3Char < name2Char)
    		if(name1Char > name2Char && name1Char > name3Char)
    			if(name2Char > name1Char && name2Char > name3Char)
    			if(name3Char > name1Char && name3Char > name2Char)
    		name1CharStr = firstChar.charAt(0);
    		name2CharStr = secondChar.charAt(0);
    		name3CharStr = thirdChar.charAt(0);
    		if(name1Char==name1CharStr || name1Char==name3CharStr)
    			if(name2Char==name1CharStr || name1Char==name3CharStr)
    		System.out.println(firstChar + secondChar + thirdChar);

    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.
