1. Given an integer n, think how you can print n '*'' characters to console using a recursive method. Then write a Java method that takes n as a parameter and prints n '*'' characters. 2. Given an input integer n, write a program that prints a number triangle of the form: 11212312312341234n 3. Write a recursive method that asks for an integer m greater than 1 , and prints integers m to 1 , separated by single spaces. For example, if you input 10, the output should be 10987654321
