Java - String regionMatches() Method

public boolean regionMatches(int toffset,
                             String other,
                             int ooffset,
                             int len)

or

public boolean regionMatches(boolean ignoreCase,
                             int toffset,
                             String other,
                             int ooffset,
                             int len)

• toffset -- the starting offset of the subregion in this string.
• other -- the string argument.
• ooffset -- the starting offset of the subregion in the string argument.
• len -- the number of characters to compare.
• ignoreCase -- if true, ignore case when comparing characters.

• It returns true if the specified subregion of this string matches the specified subregion of the string argument; false otherwise. Whether the matching is exact or case insensitive depends on the ignoreCase argument.
