I have this function to check if some words appear in a specific line, and then surround them with a given char.
The code above works like a charm, however since the words in the string array "words" are always low case, the words will be lower case as well. How can i fix this issue ?
The inputs:
BufferedReader in = "Hello, my name is John:";
char c = '*';
String [] words = {"hello","john"};
The desired output:
BufferedWriter out = "*Hello*, my name is *John*:";
The actual output:
BufferedWriter out = "*hello*, my name is *john*";
The code:
public void replaceString(BufferedReader in, BufferedWriter out, char c, String[] words){
String line_in = in.readLine();
while (line_in != null) {
for (int j = 0; j < words.length; j++) {
line_in = line_in.replaceAll("(?i)" + words[j], bold + words[j]
+ bold);
}
out.write(line_in);
out.newLine();
line_in = in.readLine();
}
}
Use
line_in.replaceAll("(?i)(" + words[j] + ")", bold + "$1" + bold);
