How I do search for the string CTG from a file that is read as a string? And then give a count of how many times it shows up? For example, how would I add code to do this in here or anywhere in general:
public String readStrFromFile(){
FileResource readFile = new FileResource();
String DNA = readFile.asString();
//System.out.println("DNA: " + DNA);
return DNA;
}//end readStrFromFile() method;
You can use Regular expression
String DNA = readFile.asString();
Pattern pattern = Pattern.compile("CTG");
Matcher matcher = pattern.matcher(DNA);
while(matcher.find()){
System.out.println(matcher.group() + " at " + matcher.start());
}
Or if the file is so big, you should use KMP algorithm or similar.
Edit :
You can have a counter for it.
int count = 0;
while(matcher.find()){
count++;
System.out.println(matcher.group() + " at " + matcher.start());
}
System.out.println("Number of count : " + count);
