Reading and Translating

Question

Hello.
I have a file which contains several lines in it.
What I'd like to do with it is to read it line by line and see if the line has a particular character in it. (for example, I'd like to find character "&" and replace it with "and" ) After examining every lines, i want to save the file in different name.
For this, I think I have to examine character by character(but im not sure how to do it).
Does anyone have some idea of how to examine characters for several lines?
Thanks for reading

Here is the method I use to translate...this method is called
public void translateFile(){
try {
fr = new FileReader (inputFile);
out = new FileWriter (outputFile);
catch (IOException e) {
System.err.println (e);
return;
try {
br = new BufferedReader (fr);
output = new PrintWriter (out);
int lineNumber= 1;
while ((line = br.readLine()) != null) {
examine(line); //each line is passed through this method
output.println(line);
lineNumber++;
output.close();
catch (IOException e) {
System.err.println (line);
System.err.println (e);
//method to examine each char
public String examine(String s){
char c;
char a ='&';
//how can I examine each like if it contains a character '&' and replace it to "and" , and put "and" into output???
return line;
}
