Thread: I'm getting a random, stringindexoutofbounds exception

This seems like some java error. I see no error with this code - in fact, it was working perfectly just a while before that. The line before the last line gives me this error: stringindexoutofboundsexceptions: String index out of range : 7, even before I compile the program and input the input.

public class person_manager {
 
	static File file = new File("C:\\Documents and Settings\\Administrator\\My Documents\\sorted_list.txt");
	static File file2 = new File("C:\\Documents and Settings\\Administrator\\My Documents\\the_person_modification_database.txt");
	static StringBuffer contents = new StringBuffer();
	static BufferedReader reader = null;
	static BufferedReader reader1 = null;
	static int count = 0;
	static int count1 = 0;
	static int listlength = 0;
	static String[] list = null;
	static String temp1 = null;
	static Path file1 =  FileSystems.getDefault().getPath("C:\\Documents and Settings\\Administrator\\My Documents\\", "sorted_list.txt");
	static person[] people_array = null;
	static int arraysize = 0;
//63
	public static void main(String[] args) throws IOException {
 
		try {
       	       		reader = new BufferedReader(new FileReader(file2));
			reader1 = new BufferedReader(new FileReader(file2));
 
	       		String text = null;
 
 
 
		        // repeat until all lines are read
 
            		while ((text = reader.readLine()) != null) {
		                contents.append(text).append(System.getProperty("line.separator"));
				count++;
            		}
 
			list = new String[count];
			people_array = new person[count/6];
			arraysize = count/6;
			count = 0;
 
			while ((temp1 = reader1.readLine()) != null) {
 
 
			if (temp1.substring(0, 2).compareTo("na") == 0 )
			{
 
			people_array[count1] = new person();
			people_array[count1].name=temp1.substring(5, temp1.length());}		
 
			try {
			if (temp1.substring(0, 2).compareTo("he") == 0 )
			{people_array[count1].height=Integer.parseInt(temp1.substring(7, temp1.length()));}
			} catch (NumberFormatException f) {people_array[count1].height=0;}
			try {
			if (temp1.substring(0, 2).compareTo("we") == 0 && (temp1.substring(6, 7).compareTo("-") != 0)  )
			{
			people_array[count1].weight=Integer.parseInt(temp1.substring(7, temp1.length()));}
			} catch (NumberFormatException f) {people_array[count1].weight=0;}
 
			if (temp1.substring(0, 2).compareTo("ey") == 0)
			{people_array[count1].eyecolor=temp1.substring(10, temp1.length());}
 
			if (temp1.substring(0, 7).compareTo("weight-") == 0)
			{people_array[count1].weight_status=temp1.substring(14, temp1.length());}

That never happens. All the lines in the file have 7 characters or more.

With an error like:
stringindexoutofboundsexceptions: String index out of range : 7,
...something happened. Time to do some debugging and see what happened where. Use a debugger or some printlns and verify your assumptions.

One day it just stopped working. Perhaps there is something wrong with the compiler.
