Question

My DB generates 3000 lines for each process and I must count some values for a report.
the generated file is like this :

CREATE TTL:NAME=SMO:0/TTS:0/UPL:1,BLQ=TRUE,NAND:TRUE,EBSPWRC=ADAPTIVE,EMSPWRC=ADAPTIVE
CREATE GPL,ASSLAPD=TSM:37/LPDLM:0,
CREATE GPL,ASSLAPD=TSM:38/LPDLM:5,
CREATE GPL,ASSLAPD=TSM:41/LPDLM:1,
CREATE GPL,ASSLAPD=TSM:21/LPDLM:8,
CREATE TTL:NAME=SMO:0/TTS:0/UPL:1,BLQ=FALSE,NAND:FALSE,EBSPWRC=ADAPTIVE,EMSPWRC=ADAPTIVE
CREATE GPL,ASSLAPD=TSM:37/LPDLM:4,
CREATE GPL,ASSLAPD=TSM:21/LPDLM:1,
CREATE TTL:NAME=SMO:0/TTS:0/UPL:1,BLQ=TRUE,NAND:TRUE,EBSPWRC=ADAPTIVE,EMSPWRC=ADAPTIVE
CREATE GPL,ASSLAPD=TSM:38/LPDLM:1,
CREATE GPL,ASSLAPD=TSM:41/LPDLM:1,
CREATE GPL,ASSLAPD=TSM:21/LPDLM:7,

Actually I want to count CREATE GPL if the BLQ and NAND be true,
Also I wrote this method that read the file line by line :

public void getGPLCount(File f) throws Exception { 
    BufferedReader br = new BufferedReader(new FileReader(f));
    String line;
    while ((line = br.readLine()) != null) {
        if (line.startsWith("CREATE TTL:NAME=") && line.contains("BLQ=TRUE") && line.contains("NAND:TRUE"))
        //___//
    }
}

thnaks for your help …

It appears as if Thomas’s answer is close, but misunderstood what you wanted. I’m just modifying his snippet.

Something like this:

int counter = 0;
boolean countLines = false;
while ((line = br.readLine()) != null) {
  if (line.startsWith("CREATE TTL:NAME=") && line.contains("BLQ=TRUE") && line.contains("NAND:TRUE")) {
    countLines = true;
  } else if (line.startsWith("CREATE TTL:NAME=") && !(line.contains("BLQ=TRUE") || line.contains("NAND:TRUE"))){
    countLines = false;
  } else if( line.startsWith("CREATE GPL") && countLines )  {
    counter++;
  }
}

So start counting every time we get BOTH BLQ=true AND Nand=true, and stop the counter if we get a TTL line missing one (or both) of those. Is this the logic you want?

UPDATE:

Matthew’s solution is also correct, but in pseudocode. Translating to Java:

int counter = 0;
boolean countLines = false;
while ((line = br.readLine()) != null) {
  // test for TTL line
  if (line.startsWith("CREATE TTL:NAME=")) { 
    countLines = (line.contains("BLQ=TRUE") && line.contains("NAND:TRUE"))
  // if TTL told us to count and it's a GPL line
  } else if(countLines && line.startsWith("CREATE GPL"))  {
    counter++;
  }
}

His answer is cleaner because he doesn’t duplicate the startsWith("CREATE TTL:NAME=") like I did. In my defense, I was trying to get you a working java example and Thomas was extremely close to what you wanted.
