Learn Java Programming - String Class Tutorials replace(...)
The replace() method is overloaded and has two different signatures. The replace(char oldChar, char newChar) simply returns a string with all characters that match the first parameter oldchar replaced with the character specified by the second parameter newChar. For example:
String s = "Don't bring these to the airport: pocket knife; liquid bleach; gasoline; guns; etc.";
String version1 = s.replace(';', ',');
System.out.println( version1); // Don't bring these to the airport: pocket knife, liquid bleach, gasoline, guns, etc.
The replace(CharSequence target, CharSequence replacement) simply returns a string with all substrings that match first parameter target replaced with the substring specified by the second parameter replacement. For example:
String u = "The quick brown fox jumps over the lazy dog.";
u = u.replace("the", "my");
System.out.println(u); // The quick brown fox jumps over my lazy dog.
