Question

Write a method called makeLine . The method receives an int parameter that is guaranteed not to be negative and a character . The method returns a String whose length equals the parameter and contains no characters other than the character passed. Thus, if the makeLine(5,':')will return ::::: (5 colons).

The method must not use a loop of any kind (for, while, do-while) nor use any String  methods other than concatenation. Instead, it gets the job done by examining its parameter , and

if zero returns an empty string

otherwise returns the concatenation of the specified character with the string returned by an appropriately formulated recursive call to itself.

Explanation / Answer

public String makeLine(int numberOfColons, char character)
{
if (numberOfColons == 0)
return "";
else
return character + makeLine(numberOfColons - 1, character);
}
