The String Object: The Power of Concatenation
The String Object: The Power of Concatenation
You can "glue" strings together
You can "glue" strings together
This is called concatenation. Concatenation is the process of gluing Strings with any other data type, including objects, such as Strings. The process to concatenate must be done through the '+' operand.
> String x = "hello" // defining a String x
> String y = "world" // defining a String y
Let us create another variable, z that will concatenate the value of x and y by using the `+` operator.
> String z = x + y
> z
"helloworld"
But also, you can incorporate more Strings or variables in between,
> z = x+" "+y
"hello world"

MOD-2.C Describe the functionality and use of program code through comments.
MOD-2.C.1 Comments are ignored by the compiler and are not executed when the program is run.
MOD-2.C.2 Three types of comments in Java include /* */, which generates a block of comments, //, which generates a comment on one line, and /** */, which are Javadoc comments and are used to create API documentation.
