| void setup() { |
| // Open serial communications and wait for port to open: |
| Serial.begin(9600); |
| while (!Serial) { |
| ; // wait for serial port to connect. Needed for Leonardo only |
| } |
| |
| // send an intro: |
| Serial.println("\n\nString replace:\n"); |
| Serial.println(); |
| } |
| |
| void loop() { |
| String stringOne = "<html><head><body>"; |
| Serial.println(stringOne); |
| // replace() changes all instances of one substring with another: |
| // first, make a copy of th original string: |
| String stringTwo = stringOne; |
| // then perform the replacements: |
| stringTwo.replace("<", "</"); |
| // print the original: |
| Serial.println("Original string: " + stringOne); |
| // and print the modified string: |
| Serial.println("Modified string: " + stringTwo); |
| |
| // you can also use replace() on single characters: |
| String normalString = "bookkeeper"; |
| Serial.println("normal: " + normalString); |
| String leetString = normalString; |
| leetString.replace('o', '0'); |
| leetString.replace('e', '3'); |
| Serial.println("l33tspeak: " + leetString); |
| |
| // do nothing while true: |
| while(true); |
| } |
