Ruby String Operations

Both concatenation and multiplication can be performed on strings.

Concatenation:

• Strings can be joined together using any of the following methods:

  • + operator
  • << operator
  • .concat method

"Hello" + " World" + "!"
# returns:
Hello World!

"Hello" << " World!"
# returns:
Hello World!

string1 = "Hello"
string2 = " World!"
string1.concat(string2)
# returns:
Hello World!

Multiplication:

• Strings can be multiplied by an integer value using the * operator.

"Hello" * 3
# returns:
HelloHelloHello
