- Method Detail
  - close
```
public void close()
```
    Close the input file.
  - eof
```
public boolean eof()
```
    Returns whether or not end-of-file has been reached.
    
    Returns:
    
    true if end-of-file has been reached, false otherwise.
  - readLine
```
public java.lang.String readLine()
```
    Read a line from the input file. Will return null if boolean eof() returns true.
    
    Returns:
    
    The line read as a String. The line-feed character is not returned.
  - readLineInt
```
public int readLineInt()
```
    Read a line consisting of a single int from the input file. If boolean eof() returns true, then this method will throw a RuntimeException.
    
    Returns:
    
    The line read as an int.
  - readLineDouble
```
public double readLineDouble()
```
    Read a line consisting of a single double from the input file. If boolean eof() returns true, then this method will throw a RuntimeException.
    
    Returns:
    
    The line read as a double.
  - readLineTokens
```
public java.lang.String[] readLineTokens()
```
    Read a line from the input file. If boolean eof() returns true, then this method will throw a RuntimeException.
    
    Returns:
    
    The line read as an array of tokens.
  - readLineInts
```
public int[] readLineInts()
```
    Read a line from the input file. If boolean eof() returns true, then this method will throw a RuntimeException.
    
    Returns:
    
    The line read as an array of ints.
  - readLineDoubles
```
public double[] readLineDoubles()
```
    Read a line from the input file. If boolean eof() returns true, then this method will throw a RuntimeException.
    
    Returns:
    
    The line read as an array of doubles.
  - loadFileAsStringList
```
public java.util.ArrayList<java.lang.String> loadFileAsStringList()
```
    Return the lines of the file in an ArrayList<String>.
    
    Returns:
    
    The lines of the file as an ArrayList<String>.
  - loadFileAsStringArray
```

```
    Return the lines of the file in a String [].
    
    Returns:
    
    The lines of the file as a String [].
  - loadFileAsIntegerList
