Syntax 1

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

Parameters
  • 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.
Returns

true if the specified subregion of this string exactly matches the specified subregion of the string argument; false otherwise.

Description

Tests if two string regions are equal.

If toffset or ooffset is negative, or if toffset+length is greater than the length of this string, or if ooffset+length is greater than the length of the string argument, then this method returns false.

Syntax 2

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

Parameters
  • ignoreCase
    if true, ignore case when comparing characters.
  • 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.
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.

Description

Tests if two string regions are equal.

If toffset or ooffset is negative, or if toffset+length is greater than the length of this string, or if ooffset+length is greater than the length of the string argument, then this method returns false.
