Java Programming

Hi,

Is there a faster way of reading in an entire file than the method I am currently reading

BufferedReader allData10 = new BufferedReader(new InputStreamReader    
	 (new FileInputStream(new File(locy)),"UTF8"));  
	 
       String combine = "";
       String S;
       System.out.println("getO2");
       while ((S = allData10.readLine()) != null ){
    	 combine +=  (S +"\n");   	  
	       }

I don't need to read a line at a time, so wondering if this can be vastly improved.
