1. Looping Through Strings

2. String Loops Usually a for-loop – do you know why? Where would the loop start? Where would the loop stop?

3. What does it do? for(int i = 0; i< word.length(); i++){ char letter = word.charAt(i); System.out.println(letter); }

4. Running Totals Sometimes our “running total” or “accumulator” variable should be a string. Start it at “” Use concatenation to add to it

5. Creating a String String word = “Happy”; String newWord = “”; for(int i = 0; i< word.length(); i++){ char letter = word.charAt(i); newWord = newWord + letter; }

6. Practice Write a loop that takes a String and returns the string with all the e’s removed. For example, removeE(“elephant”) should return “lphant” public String removeE(String word) Write a loop that prints a word vertically. public void verticalPrint(String word) For example, verticalPrint(“Hey”) prints: H e y
