What is the startsWith() method?

Rating:

The startsWith() method of the String class checks whether a given string starts with a specified string or not. It returns boolean true if the string matches, otherwise returns false.

The general form of this method declaration is as follows:

boolean startsWith (String str)

Here, str specifies the string being tested.

For example:

Football.startsWith ("Foo")

returns true as the string starts with Foo.

The other form of the startsWith() method declaration is as follows:

boolean startsWith(String str, int startIndex)

Here, startIndex specifies the starting index of the invoking string at which the search will begin.

For example, Football ("ball", 4)

returns true, as the string, ball, starts from the specified index, i.e., 4.
.
Note: This method is case-sensitive, i.e., it differentiates between java and JAVA.
