Ruby Language Strings Positioning strings
Example
In Ruby, strings can be left-justified, right-justified or centered
To left-justify string, use the ljust method. This takes in two parameters, an integer representing the number of characters of the new string and a string, representing the pattern to be filled.
If the integer is greater than the length of the original string, the new string will be left-justified with the optional string parameter taking the remaining space. If the string parameter is not given, the string will be padded with spaces.
str ="abcd"
str.ljust(4) => "abcd"
str.ljust(10) => "abcd "
To right-justify a string, use the rjust method. This takes in two parameters, an integer representing the number of characters of the new string and a string, representing the pattern to be filled.
If the integer is greater than the length of the original string, the new string will be right-justified with the optional string parameter taking the remaining space. If the string parameter is not given, the string will be padded with spaces.
str = "abcd"
str.rjust(4) => "abcd"
str.rjust(10) => " abcd"
To center a string, use the center method. This takes in two parameters, an integer representing the width of the new string and a string, which the original string will be padded with. The string will be aligned to the center.
str = "abcd"
str.center(4) => "abcd"
str.center(10) => " abcd "
