What does the stringUtils Equals method do and how does it work?
I have a solution that currently uses the stringUtils1.Equals method, but I'm not entirely sure what it does as I cannot seem to find any information on it anywhere. Ive tried to determine what its purpose is, but as there is only 1 input (obj), how could it possibly be decided if it is equal to something if it has nothing to compare it to? what does the "obj" input name stand for, "object"?

Hi Ryan,
Yes obj stands for object.
this another method to check if this one obj exists or not :
See the logic:
ublic static boolean equals(String str1, String str2)
-
Compares two Strings, returning
trueif they are equal.nulls are handled without exceptions. Twonullreferences are considered to be equal. The comparison is case sensitive.StringUtils.equals(null, null) = true StringUtils.equals(null, "abc") = false StringUtils.equals("abc", null) = false StringUtils.equals("abc", "abc") = true StringUtils.equals("abc", "ABC") = false
