Thread: Personality Test Grader Help

Hi. I am supposed to make a computer program that is designed to grade the classic myersBriggs test. There is a text file that i have to import the information from and then use it to determine the personailty with four dimensions. I am having major issues with this problem. Any help would be appriciated.

public class MyersBrigg
{		
	private static int JP = 0;
	private static int TF = 0;
	private static int SN = 0;
	private static int IE = 0;
	public static String[][] answers;
 
public String[][] getArray() throws IOException
{	
	// Open the file
	PrintWriter outputFile = new PrintWriter("C:/MB.txt");
 
	// Write the array elements to the file
	for (int row = 0; row < answers.length; row++)
	{
		for (int col = 0; col < answers[row].length; col++)
			outputFile.println(answers[row][col]);
	}
 
	// Close the file
	outputFile.close();
 
	return answers;
}
 
public void getAnswers()
{
	int row = 1;
 
	if ( row < answers.length);
	{
		int col = 0;
 
		if ( col < answers[row].length);
		{
			if (answers[row][col].equalsIgnoreCase("B"))
			{	
				IE++;
				col++;
			}
 
			if (answers[row][col].equalsIgnoreCase("B"))
			{	
				SN++;
				col++;
			}
 
			if (answers[row][col].equalsIgnoreCase("B"))
			{	
				SN++;
				col++;
			}
 
			if (answers[row][col].equalsIgnoreCase("B"))
			{	
				TF++;
				col++;
			}
 
			if (answers[row][col].equalsIgnoreCase("B"))
			{	
				TF++;
				col++;
			}
 
			if (answers[row][col].equalsIgnoreCase("B"))
			{	
				JP++;
				col++;
			}
 
			if (answers[row][col].equalsIgnoreCase("B"))
			{	
				JP++;
				col++;
			}
 
		}
	}
	row += 2;
}
 
 
public static String[] getPersonality(String answer)
{
 
	// Create String Array object
	String[] personality = new String[4];
 
		if (IE < 4)
			personality[0] = "I";
		else 
			personality[0] = "E";
 
		if (SN < 5)
			personality[1] = "S";
		else 
			personality[1] = "N";
 
		if (TF < 5)
			personality[2] = "T";
		else
			personality[2] = "F";
 
		if (JP < 5)
			personality[3] = "J";
		else
			personality[3] = "P";
 
		return personality;
}	
public static String printAnswers(String answer)
{
	int A_IE = 20 - IE;
	int A_SN = 20 - SN;
	int A_JP = 20 - JP; 
	int A_TF = 20 - TF;
 
    String answers = A_IE + "A-" + IE +"B " + A_SN +"A-" + SN +"B " 
    		+ A_JP + "A-" + JP + "B " + A_TF + "A-" + TF + "B";
 
	return answers;
}
public static String printPercents(String answer)
{
    String percents = "[" + IE/10 + ", " + SN/20 + ", " + JP/20 + ", " + TF/20 + "]";
 
    return percents;
}
}
 
 
and my main class is as follows
 
public class TestResults
{
	public static void main(String[] answer)
	{
		int row = 0;
		int col = 0;
 
		for (row = 0; row < MyersBrigg.answers.length; row++);
		{
			for (col = 0; col < MyersBrigg.answers[row].length; col++)
				System.out.println(MyersBrigg.answers[row][col]);
 
				row++;
				System.out.println(MyersBrigg.printAnswers(MyersBrigg.answers[row][col]));
				System.out.println(MyersBrigg.printPercents(MyersBrigg.answers[row][col]) +
						MyersBrigg.getPersonality(MyersBrigg.answers[row][col]));			
		}
		System.out.println("There are no more test to score!");
	}
}

I am fairly new to this. and am getting an error in my main thread. first it was a nullPointerException. and then a no method error. Now i am gettin this
Exception in thread "main" java.lang.Error: Unresolved compilation problem:

at TestResults.main(TestResults.java:13)

Please help me guys!

Yes i am getting compliation errors. heres what the console in eclipse says.

Exception in thread "main" java.lang.Error: Unresolved compilation problem:

at TestResults.main(TestResults.java:13)

which I believe is the line that is the main

public static void main(string[] args)

I hope this works. and makes it look more correct with line numbers. i tried using the format you suggested. I am VERY new to this. and I am unaware of how to find the errors from the compiler. Within eclipse there says there are no errors on the left when typing the code, but it just wont run correctly.

Thanks in advance for any help!

How do I see the compiler errors. sorry I am very new to this. and cant figure out how to find that.

I am using eclipse and if you mean the problems it displays next to the javadoc and console there are no warnings or errors. no syntax errors. nothings I can see. but thanks for the help anyways. I will do what I can to figure things out ..
