Exercises Four static methods

1. Write 4 overloading static methods to construct a String that compose a diamond: public static String diamond (); public static String diamond (int n); public static String diamond (int n, char flash); public static String diamond (int n, char flash, char blank); System.out.print( diamond() ) will output as left below:

System.out.print( diamond( 5 ) ) will output as right above. System.out.print( diamond( 7, ’$’ ) ) will output as left below:
System.out.print( diamond( 6, ’@’, ’.’ ) ) will output as right above.

2. Write a static methods that remove all the tabs (\t) in a String and substitute a tab with needed blanks. public static String noTabs (String s, int tabPosition); For example, noTabs( ”\tabcde\t1234\txyz\tABCDEFGHIJKLMN\tOK\n”, 8) will return the String: ”........abcde...1234....xyz.....ABCDEFGHIJKLMN..OK\n”. For clarity, using a . to present a blank. And noTabs( ”\tabcde\t1234\txyz\tABCDEFGHIJKLMN\tOK\n”, 4 ) will return the String: ”....abcde...1234....xyz.ABCDEFGHIJKLMN..OK\n”.
3. (jhtp10, Exercise 5.29) “The Twelve Days of Christmas” Song. Write an application that uses repetition and switch statements to print the song “The Twelve Days of Christmas.” One switch statement should be used to print the day (“first,” “second,” and so on). A separate switch statement should be used to print the remainder of each verse. Visit the website en.wikipedia.org/wiki/The_Twelve_Days_of_Christmas_(song) for the lyrics of the song. (12DaysOfChristmas.txt attached)
Typical switch statament is something like:
switch (integrelExpression) { // integerals, String, enum type case c1: // a constant .. break; // might be falling down case c2: .. break; .. case cn: .. break; default: .. break; }
