Example method specification: public static void writeLine(char ch, int n) public static void writeBlock(char ch, int n, int m)

3. Write a recursive Java method writeLine that writes a character repeatedly to form a line of n characters. For example, writeLine( 5) produces the line ** Then write a recursive method writeBlock that uses writeLine to write m lines of n characters each. For example, writeBlock(*',5,3) produces the output
