One tuff parsing question?

Question

I read in three lines of data.
This is what the data looks like:
Joe|22|math|A
Ladan|21|english|C
Kyle|22|accounting|F
Can someone please show me code that will return a string that looks like this...
return String Results = "math|english|accounting";

Answer 1

Try this:
BufferedReader br=new BufferedReader(new InputStreamReader(inputStream));
String nextLine="";
String retStr="";
StringBuffer sBuf=new StringBuffer();
char pChar='|';
int pLoc=2;
while((nextLine=br.readLine())!=null) {
try {
retStr=doStuff(nextLine, pLoc, pChar);
catch(Exception ex) {
System.out.println("Error parsing a line");
continue;
sBuf.append(retStr);
sBuf.append(pChar);
String lastStr=sBuf.toString();
lastStr.substring(0, lastStr.length()-1);
public String doStuff(String thLine, int pLoc, char pChar)
throws Exception {
//pLoc is the index of the token to find
//pChar is the delimiter character
int lLen=thLine.length();
int stInd=0;
int fiInd=-1;
for(int count=0;;count++) {
stInd=thLine.indexOf(pChar, stInd);
if(stInd==-1)
throw new Exception();
if(count==pLoc) {
fiInd=thLine.indexOf(pChar, stInd+1);
if(fiInd==-1)
return thLine.substring(stInd+1, thLine.length());
return thLine.substring(stInd+1, fiInd);
stInd+=1;
}
