string - JAVA - reading from text file, recognizing new lines -

i have task read text file several lines, after need count every character's unicode value, sum of "hello" 532 , "how you" 1059 , on, every string begins on new line in .txt document , far good. every line need print own value, , way code works, adds every line's value , cant head around way stop when end of lxtine comes looks like: *read line *count char values *add *print them *start on next line, ,

import java.io.bufferedreader; import java.io.filereader; import java.io.ioexception; import java.io.reader; import java.lang.string; import java.util.arrays;  public class sumlines {      public static void main(string[] args) {          string filepath = "/home/lines.txt";          string readline;         int sum = 0;          try (bufferedreader bufferedreader = new bufferedreader(new    filereader(filepath))) {             while ((readline = bufferedreader.readline()) != null) {                 char[] array = new char[readline.length()];                 system.out.println(readline);                  (int = 0; < readline.length(); i++) {                      arrays.fill(array, readline.trim().charat(i));                     sum += (int) array[i];                      system.out.print(sum + " ");                 }             }         } catch (ioexception e) {             system.out.println("error.\n invalid or missing file.");             e.printstacktrace();         }        system.out.println("\n*** final " + sum);     } } 

if understood correctly, input:

hello how 

you output:

hello 532 how 1059  *** final 1591 

for this, need make modifications code:

• in addition calculating sum of characters values per line, keep sum of total of lines
• for each input line, print line followed sum of character values
• you don't need array @ all
• it's better trim input line once, instead of every character

like this:

    int total = 0;      try (bufferedreader bufferedreader = new bufferedreader(new    filereader(filepath))) {         string readline;         while ((readline = bufferedreader.readline()) != null) {             string trimmed = readline.trim();             int sum = 0;             (int = 0; < trimmed.length(); i++) {                 sum += (int) trimmed.charat(i);             }             system.out.println(readline + " " + sum);             total += sum;         }     } catch (ioexception e) {         system.out.println("error.\n invalid or missing file.");         e.printstacktrace();     }     system.out.println("\n*** final " + total);
