The creation of an instance of the Class, an String object is easy. You only need to put the characters inside quotation marks:

String myString = "Hello World!";

For the use of the methods you can use the prefix: String or sometimes the value of the string itself.

A property:

Length

And the methods:

Compare(somestring, otherstring, boolean)

Compares two specified String objects, ignoring or honoring their case.

Concat(somestring, otherstring)

IndexOf(somechar)

Returns the position of the first occurrence of "somechar" (or somestring). This research can be made from an initial position to an end position.

IndexOf(somechar,init)

IndexOf(somechar ,init, end)

Insert(init,somestring)

Join(separator ,somearray)

The method Split does the reverse of Join

Split(somearray,separator)

LastIndexOf(somechar,init)

LastIndexOf(somechar ,init, end)

PadLeft(somelength)

PadRight(somelength)

Will add blanks to the string until we have "somelength".

Remove(init, quantityofchars)

Replace(oldchar, newchar)
