  1. POWhy am I getting an EOF Exception in Java?
    text
    copied!<p>I wrote the following method to read a file, search for a certain character "$", and return a boolean indicating whether it is present or not. For some reason, I keep getting a EOFException at line 224, where it simply says "s = raf.readUTF". All I'm doing is reading the records and adding them to an array list. Here is the code:</p> <pre><code> public boolean buildComparisonArray(String passedPath) throws FileNotFoundException, IOException{ ArrayList&lt;String&gt; comparisonArray = new ArrayList&lt;String&gt;(); boolean unwantPresent = false; File file = new File(passedPath); RandomAccessFile raf = new RandomAccessFile(file, "r"); raf.seek(0); long num = 0; long fileSize = 0; int record = 0; fileSize = raf.length(); record = 160; num = fileSize/record; String s = "", s2 = "", s3="",s4="",s5="",s6="",s7="",s8=""; long currentPositionOfFilePointer; for(int i=0; i&lt;num; i++){ currentPositionOfFilePointer = raf.getFilePointer(); System.out.println("Current: "+currentPositionOfFilePointer); s = raf.readUTF(); comparisonArray.add(s); System.out.println("Found in file: "+s); for(int j=0; j&lt;20-s.length();j++){ raf.readByte(); } s2 = raf.readUTF(); comparisonArray.add(s2); System.out.println("Found in file: "+s2); for(int j=0; j&lt;20-s2.length();j++){ raf.readByte(); } s3 = raf.readUTF(); comparisonArray.add(s3); System.out.println("Found in file: "+s3); for(int j=0; j&lt;20-s2.length();j++){ raf.readByte(); } s4 = raf.readUTF(); comparisonArray.add(s4); System.out.println("Found in file: "+s4); for(int j=0; j&lt;20-s2.length();j++){ raf.readByte(); } s5 = raf.readUTF(); comparisonArray.add(s5); System.out.println("Found in file: "+s5); for(int j=0; j&lt;20-s2.length();j++){ raf.readByte(); } s6 = raf.readUTF(); comparisonArray.add(s6); System.out.println("Found in file: "+s6); for(int j=0; j&lt;20-s2.length();j++){ raf.readByte(); } s7 = raf.readUTF(); comparisonArray.add(s7); System.out.println("Found in file: "+s7); for(int j=0; j&lt;20-s2.length();j++){ raf.readByte(); } s8 = raf.readUTF(); comparisonArray.add(s8); System.out.println("Found in file: "+s8); for(int j=0; j&lt;20-s2.length();j++){ raf.readByte(); } } raf.close(); for(String j: comparisonArray){ if(j.contains("$")){ unwantPresent = true; }else if(!j.contains("$")){ unwantPresent = false; } } return unwantPresent; } </code></pre> <p>All i'm trying to do is read through a random access file of one line and check whether or not the "$" symbol is present. </p>
