Il metodo di String equalsIgnoreCase

equalsIgnoreCase

public boolean equalsIgnoreCase(String anotherString)

Compares this String to another String, ignoring case considerations. Two strings are considered equal ignoring case if they are of the same length and corresponding characters in the two strings are equal ignoring case.

Two characters c1 and c2 are considered the same ignoring case if at least one of the following is true:

• The two characters are the same (as compared by the == operator)
• Applying the method Character.toUpperCase(char) to each character produces the same result
• Applying the method Character.toLowerCase(char) to each character produces the same result

Parameters:

anotherString - The String to compare this String against

Returns:

true if the argument is not null and it represents an equivalent String ignoring case; false otherwise

Esempio:

String nome="Mario";
... nome.equalsIgnoreCase("Mario")  ritorna true
... nome.equalsIgnoreCase("Maria")  ritorna false
... nome.equalsIgnoreCase("maRiO")  ritorna true
... nome.equalsIgnoreCase("maRiA")  ritorna false
