The equalsIgnoreCase() method compares two strings irrespective of the case (lower or upper) of the string. This method returns true if the argument is not null and it represents an equivalent String ignoring case, else false.
str2.equalsIgnoreCase(str1); Here str1 and str2 both are the strings which we need to compare.
str1: This is a string which needs to be compared.
This method returns true if the argument is not null and it represents an equivalent String ignoring case, else false.
Input : str1 = "pAwAn"; str2 = "PAWan" str2.equalsIgnoreCase(str1); Output :true Input : str1 = "powAn"; str2 = "PAWan" str2.equalsIgnoreCase(str1); Output :false Explenation: powan and pawan are different strings.
str2 is equal to str1 = true str2 is equal to str3 = false
