2Learning Goals•Be able to write string algorithms that operate on each character. •Be able to build up new strings from existing strings using built-in String methods.
3Plan For Today•Recap: Characters and Strings•Looping over Strings•Practice: Reversing a String•Practice: Palindromes•Practice: Caesar Cipher

6CharA charis a variable type that represents a single character or "glyph".charletterA= 'A';charplus = '+';charzero = '0';charspace = ' ';charnewLine= '\n';chartab = '\t';charsingleQuote= '\'';charbackSlash= '\\';
7CharUnder the hood, Java represents each charas an integer(its "ASCII value"). •Uppercase letters are sequentially numbered•Lowercase letters are sequentially numbered•Digits are sequentially numberedcharuppercaseA= 'A';// Actually 65charlowercaseA= 'a';// Actually 97charzeroDigit= '0';// Actually 48
